After repeated tempering, quenching into steel.
China Baowu Masteel Group (hereinafter referred to as "Masteel") relies on the "Masteel spirit" that takes the lead, relies on hard work, self-accumulation, and rolling development to build China's first wheel hub, the first set of high-speed wire rod rolling mill, and "China's First Steel Stock"(A+ H-share listed company), the first hot rolled H-shaped production line, and the first heavy-duty H-shaped beam production line were born here.
On August 19, 2020, General Secretary Xi Jinping pointed out during an inspection and investigation at Masteel that we must grasp our own advantages, comply with the current trend of enterprise modernization development, and seize opportunities in the reform and development of modern enterprises, especially in the integrated development of the Yangtze River Delta., follow the trend, and make our own contribution to the integrated development of the Yangtze River Delta.
Standing at a new starting point, Magang people keep in mind the General Secretary's instructions, adhere to the original intention of serving the country with steel, bravely shoulder the mission of a manufacturing power, comply with the development trend of high-end, intelligent and green manufacturing, transform and upgrade secondary entrepreneurship, and embark on a new journey of high-quality development.

01 cross the cycle:From No. 9 Blast Furnace to Youte Steel Quality Base

Since its birth, Ma Steel has shouldered the mission of "serving the country with steel". Its predecessor, Ma 'anshan Ironmaking Plant, was included in the national "First Five-Year Plan" and became part of the basic pattern of the steel industry in New China that was "divided into north and south and supported at multiple points." With the support of builders from all over the country, at 18:05 on September 16, 1953, the first furnace of molten iron poured out in East China after the founding of New China. By the beginning of this century, Masteel had developed into a large-scale steel complex integrating iron, steel and steel products.
Entering the new era, Magang has taken the lead in actively participating in supply-side structural reforms and actively integrating into the integrated development of the Yangtze River Delta.
De-production capacity, the strong man breaks his wrist.
With the joint efforts of all steelworkers, China has become a "major steel country" with output ranking first in the world year after year. However, the large number of companies, disorderly competition, and low industrial concentration are still pain points in the industry.
From 2016 to 2018, Masteel Group "should do everything possible" to resolve excess production capacity, shut down all production lines in the old factory area, and achieve large-scale and modernization of the overall equipment. In the past three years, Masteel withdrew 2.24 million tons of iron-making production capacity and 2.69 million tons of steel-making production capacity, diverting and resettling more than 18,000 employees.
In the Masteel Exhibition Hall, there is quietly lying a "Permanent Suspension of Production Commemoration" iron plaque cast with the last hot iron of No. 9 blast furnace. The No. 9 blast furnace is the first modern blast furnace of more than 200 cubic meters in East China that was completed and put into operation in 1958. In the same year, Chairman Mao Zedong inspected Masteel and boarded the No. 9 blast furnace platform. April 23, 2018 was a rainy day. Dozens of workers at the scene watched as the fire of No. 9 blast furnace, which had been operating safely for 60 years, slowly went out.
"The blast furnace kindling put into construction and use by Masteel is all taken from the No. 9 blast furnace. Although the No. 9 blast furnace has stopped production, the spirit of Masteel it represents is still passed down from generation to generation." According to the staff of the exhibition hall, the No. 9 blast furnace will be permanently preserved as a patriotic education base and industrial site.
Promote concentration and take the lead in action.
After experiencing the tempering of de-production capacity, China's steel industry has become stronger. Under the trend of reduction and development in the steel industry, the survival of the fittest in the market is intensifying, and the reorganization and integration of steel enterprises is imperative.

从地图上看，马鞍山位于长三角地理几何中心，是安徽省融入沪苏浙的桥头堡。2019年9月，作为深化供给侧结构性改革、落实长三角一体化发展战略的重要举措，马钢集团与中国宝武集团实施战略重组。随着此后太钢集团、新钢集团等地方钢企相继加入，中国宝武成为产量全球第一的亿吨级世界级钢铁企业，改写了中国乃至世界钢铁业的格局。
在中国宝武以沿海为弓、以长江为箭的“弯弓搭箭”版图上，马钢肩负着建设中国宝武优特钢精品基地的新使命。
This is a mobilization order for high-quality development and starts a new journey of Masang's second entrepreneurship and transformation and development. “我们要牢记国之大者，勇当高质量发展的排头兵，增强核心竞争力，坚定不移打造后劲十足大而强的新马钢。”马钢集团党委书记、董事长丁毅表示。
“作为衡量一国钢铁工业制造水平的重要标志，特种钢材是建设现代化强国不可或缺的关键材料,也是技术含量和附加值最高、目前遭遇‘卡脖子’最严重的钢铁材料。”中国国际工程咨询有限公司专家学术委副秘书长陈子琦介绍，虽然中国钢材自给率已连年突破98%，但仍有大约70多种短板材料，其中有50多种是特钢。
长期以来，随着产能不断扩大，马钢形成了“大而全”的产品结构和产业链条，其好处在于东边不亮西边亮，有利于抵御市场波动的风险。但四面出击、不够聚焦，也导致长板不长、优势不彰。
**成为头部企业，才有头部效益。**好钢用到刀刃上，走极致专业化道路，是高质量发展的不二选择。加入中国宝武一盘棋，马钢得以谋篇布局，全力干好最擅长干的事。
钢铁市场是典型的周期性市场。自2022年下半年开始，在生产成本上升和市场供过于求的双重挤压下，包括马钢在内的多家钢铁生产企业业绩下滑，甚至陷入亏损。
“中国钢铁业正在进入深度调整期。”陈子琦分析，钢铁市场中长期进入存量竞争阶段，普钢领域已成竞争红海，钢铁企业必须打造自己的核心竞争力。
作为一家老钢铁企业，马钢习惯将市场的跌宕起伏视为增强企业质地的淬炼。只有把自己锤炼成一块“特钢”，才能锻造穿越周期的钻头。

The characteristics of "special steel" lie in its quality and toughness. “马钢正处于战略转型的关键时期、项目建设的爬坡阶段，叠加市场周期性波动，压力确实很大。但我们坚信高质量发展的方向是正确的。”丁毅说，在行业承压的背景下，马钢一方面以变应变、适应市场变化，拓渠道、降库存；另一方面苦练内功、坚持转型发展，优结构、提效率。2023年四季度以来，经营绩效持续大幅改善，成为中国宝武有效应对钢铁寒冬的典型案例。
3年多来，马钢人均产钢量翻了一番。即使在整体低迷的市况中，高附加值产品也展示出良好前景。2023年，H型钢、车轮出口创历史新高、同比增长47.17%，车轮年产突破60万件、同比增长12%。
总投资90多亿元、占地上千亩的新特钢项目是马钢二次创业的标志性项目。
“一年当作三年干、三年并为一年干”，“马钢速度”再次刷新纪录：18个月时间里，完成被称为“移山”行动的桃核山场平工程、人头矶边坡治理项目，以及9号高炉工业遗址搬迁。
2023年6月6日，在9号高炉的原址上，马钢集团新特钢项目一期工程点火成功。项目投产以来，瞄准轴承钢、齿轮钢、弹簧钢、非调质钢、合金冷镦钢等中高端市场，累计开发新产品160多个，为长三角一体化发展提供有力的材料支撑。
02 Innovation wins:Entering the "no man's land"

At 7:23 on January 1, 2024, facing the dawn of the New Year, China's first "Fuxing" long-consist EMU G364 equipped with Chinese-made high-speed wheels drove out of Wuhan Station, marking the development of Masteel The high-speed rail wheels have entered the stage of loading and using China's high-speed rail trains.
At the China Rolled Steel Wheel Exhibition Hall of Masteel Rail Transportation Materials Technology Co., Ltd.(hereinafter referred to as "Masteel Transportation Materials"), the "China Standard EMU Fuxing" wheel running at 350 kilometers per hour, the world's first heavy-duty wheel with an axle weight of 45 tons, green and environmentally friendly wheels that fill the gap in domestic subway applications and other highlights.
The most dazzling thing to Magang people is the rusty wheel hub in the exhibition hall. In the 1960s, Comrade Deng Xiaoping decided to build a wheel and hub factory in Ma 'anshan. The advent of Chinese-made train hubs and rolled steel integral wheels ended China's long-term reliance on "foreign wheels and hubs". Masang's "fighting wheel" has become famous.
With the repeated speed-ups of China's railways, the "competitive wheel" has passed through the steam era and the bullet train era, and entered the era of high-speed rail. "High-speed rail is a representative of China's high-end equipment manufacturing, but the ones you wear on your feet are still 'foreign shoes'." Lu Song, chief engineer of Masteel's Materials Technology Center, said,"The 'competition wheel' must fight for another breath, break the monopoly with independent innovation, and let the high-speed rail wear 'Chinese running shoes'!"

Four pairs of wheels support a high-speed rail carriage, and each pair of wheels has to withstand more than ten tons of pressure for a long time; when driving, the wheels turn dozens of revolutions per second, ensuring that the mass on either side of the track when turning is almost the same; withstand each time The high temperatures of thousands of degrees Celsius caused by the huge friction during starting and braking must withstand a low temperature environment of minus 60 degrees Celsius...
With high technical requirements, high production difficulty, and high processing precision, the research and development and production of high-speed wheels are recognized as the "tip of the pyramid" of industrial manufacturing. A few foreign companies with production capabilities all list this as a core technology and adopt the "three noes" confidentiality measures of "not applying for patents, not publishing papers, and not accepting exchanges and visits."
Since 2008, Masteel has continued to tackle key problems in the manufacturing of high-speed rail wheels in China. Hundreds of R & D personnel have been invested, dozens of rounds of industrial tests have been carried out, and hundreds of patents have been obtained. From 200 kilometers per hour to 250 kilometers per hour, from 350 kilometers to 400 kilometers, Masteel's wheels are running faster and faster. In June 2023, Masteel's high-speed wheels set a record of 453 kilometers per hour in a single row.
In the workshop, stacks of shiny wheels are ready to go. On the display wall, certificates such as EU TSI certification, British RISAS certification, and international railway industry standard certification are full of weight. "Masteel's high-speed rail wheels have been exported to more than 70 countries and regions." Wang Zhigang, deputy director of Masang Jiaomei Wheel and Axle Factory, said proudly.

“时速每提高50公里，平均需要5年研发时间。”马钢技术中心车轮研究所所长刘学华说，马钢高速车轮的研发已进入时速400公里以上以及超低温、大风沙等恶劣环境应用的“无人区”。
2023年在杭州举行第19届亚运会期间，装用马钢弹性车轮的“亚运号”地铁列车，成为杭州市区一道流动的风景线。与高铁车轮内部结构高度一致不同，弹性车轮剖面像块三明治，两层钢铁件中间的压缩橡胶必须与车轮斜面百分百贴合。在此之前，马钢没有任何相关制造经验。在马钢交材车轮车轴厂生产协调员、技能大师沈飞的率领下，团队从头做起，建立数学模型、自制测量工具，光是刀具选型、参数调整就做了上百种方案，经过两年多持续攻关，实现了10多个品种的小批量生产制造。
敢于一马当先、勇闯“无人区”的精神，是马钢在数十年传承中生长出来的可贵基因，已经深深刻印在发展的每一个足迹中。
应用于电力、化工、桥梁、隧道等领域的重型H型钢，可以在节约用钢量的同时提升建筑强度，代表了未来的发展方向。2020年4月，马钢建成投产全球第五条、中国首条重型H型钢生产线，具备了重型、厚壁、宽翼缘H型钢的生产能力；3年多时间里，中国制造的钢筋铁骨开始有力托举起港珠澳大桥、北京冬奥会场馆、海洋钻井平台。
In the repeated challenges to extreme specifications, Masteel's manufacturing capabilities have achieved breakthroughs one after another. 马钢长材事业部技能大师圣立芜回忆，在早期生产中，因钢坯重量导致轧制扭矩过大，轧机经常卡钢，只好一次次停机报废，调整工艺后再从头轧制。“现在马钢能轧制高度1172毫米的H型钢产品，是目前国内的最大块头。”他说。

From the country's important equipment to the needs of people's livelihood, Masteel has used technological innovations to ensure national economic security and the stability of industrial and supply chains.:
More than 2000 products in Masteel's four series of wheels, hub rings, axles, and wheelsets have covered the entire wheel spectrum of freight, passenger and cargo movements and urban rail transportation; 500 MPa low-temperature steel bars that can withstand temperatures of minus 165 degrees Celsius make China's liquefied natural gas storage tanks use Chinese-made steel; one out of every three desktop computers, every five air conditioners, and every six refrigerators in the domestic market uses home appliance panels produced by Masteel...
"General Secretary Xi Jinping has clearly requested to strengthen the research and development of new materials and new technologies, develop and produce more new products with high technical content and high added value, and enhance market competitiveness." Mao Zhanhong, deputy secretary of the Party Committee and general manager of Masteel Group, said that over the past three years, Masteel has adhered to innovation leadership, and 27 new products have achieved national launches, 3 of which are global launches. A total of 3.71 million tons of new products have been developed and produced, and the sales rate of new products has increased from 6.3% to more than 9%.
"The so-called first product means that we have to make it first. R & D must always be one step ahead and one step faster, so that once market demand arises, it can be quickly transformed into products." said Zhu Tao, deputy director of the Masang Technology Center of China Baowu Academia Sinica.
Since 2020, with the support of China Baowu, Masteel's innovation efforts have continued to increase, and the R & D investment rate has increased from 2.22% in 2020 to 4% in 2022, reaching the advanced level in the same domestic industry. At present, Masteel Group has more than 2000 R & D personnel, accounting for 11% of the total employees. It has established a technological innovation organizational structure with the Professional Technical Management Promotion Committee as the decision-making level, the R & D unit as the main body, and each manufacturing unit as the auxiliary body. As of the end of 2023, Masteel has more than 3500 patented inventions and more than 4800 technical secrets, ranking among the top of the patent innovation index of Chinese steel companies.
In June 2023, the R & D building of Masteel Technology Center was completed, and the exterior facade of the glass curtain wall shone brightly. Core laboratories such as excellent and special materials, rail axles, high-quality plates and belts, and low-carbon metallurgy have been built in the R & D building, gathering national-level enterprise technology centers, academician workstations, postdoctoral workstations and multiple innovation platforms. "This will become an important innovation platform for promoting the manufacturing process of high-speed axles in China and building a high-quality base for special steel. It is also an important part of China Baowu's efforts to build a world-class enterprise research institute." Zhu Tao said.

03 Digital empowerment:Steelmaking is a tempering of people

加快智造升级，是钢铁业实现质量变革、效率变革、动力变革的基础保障，推动新质生产力形成。在马钢，记者看到传统钢铁企业的面貌正在被数智化大潮所改变。
On one side is the roaring production site. 以往每次站到热浪滚滚的钢卷前“打码”，马钢长材事业部工作人员贾龙杰都深吸一口气，举起左臂护住脸部以防烫伤，右臂则举起绑着油笔的1米多长竹竿，将13位编号写到钢卷侧面，用时需要5分钟左右。一天之中，身上衣服总是湿了干、干了湿。
如今，身高约1.8米、身着银色铝箔防护服的“宝罗”轻展“手臂”，几秒钟便完成一卷钢卷的“打码”。贾龙杰现在每天上班后第一件事就是给“宝罗”穿上防护服。
“宝罗”是宝武机器人BAO Robot的“小名”。马钢现有489位“宝罗”，都是有编号的员工。钢卷拆捆、测温取样、高炉巡检……分布在各个车间的“宝罗”，正在代替高温、煤气、粉尘、噪音环境下的人工工作。
On one side is the bright and quiet operation center. 马钢智园是整个集团的“智慧大脑”。在几座掩映在树丛中的橘红色低矮建筑里，密布的巨型显示屏、错落的操作岛台、安静的工作环境，以及工作区域旁的咖啡座，使这里看起来更像是一家科技型公司。
现场操控室一律集中、操作岗位一律采用机器人、运维监测一律远程、服务环节一律上线。电脑屏幕上，生产现场情况、产线指标数据一目了然；“动动手指”之间，一键倒罐、一键脱硫、一键炼钢、一键出钢、一键精炼……越来越多的线上、远程操作，既提高了生产效率，又实现了本质安全。
“信息化、智能化带来管理扁平化，极大地提高了组织生产效率、决策效率，促使生产管理从粗放的大平衡管控向全流程精益管理转变。”马钢股份总经理助理杨兴亮介绍，马钢一向有精益管理的传统，20世纪60年代就曾以“三清、五不漏、规格化、一条线”的文明生产经验闻名全国，在行业内有“江南一枝花”的美称。以智能制造赋能精益管理，是马钢近年着力探索的课题，但一直受基础设施落后、更新迭代不够等因素制约，进展不快。加入中国宝武后，依托其成熟的工业互联网平台，马钢聚焦“全流程、全工序、全要素、全集成”，积极探索传统长流程钢铁企业智慧制造升级新模式，构建了“1个管控中心+10个智控中心”“一厂一中心”智控模式。

第一个智控中心是冷轧总厂在一栋仓库基础上改建而成的。时间表记录了令人惊叹的速度：2020年3月，方案通过评审；4月份，地基处理；7月底，内部装修；9月份，设备安装。
冷轧总厂电气设备首席工程师陈立君还记得，那年国庆节放假前一天，智控中心的照明灯还没启用，几位工作人员借着施工探照灯的光亮，在电脑上设置好系统参数。接下来，他们“看着”数公里外的生产车间里，现场工作人员协助带钢上卷后，生产线开始运转，开卷、剪切、分卷、取样、卸卷。“看到马钢远程生产的第一卷钢，大家都由衷感到自豪。虽然系统仍需要完善，但已经是质的飞跃，一切的努力都值得！”回忆起那个时刻，陈立君至今仍难掩激动。
冷轧总厂厂长严开龙告诉记者，智控中心的建成，使冷轧总厂跨越南北两区、分散在5地、直线距离超过10公里的17条生产线、51个操作室，实现了同处一室集控。
按照“一厂一中心”模式，炼铁、炼钢、热轧等总厂或分公司先后建起各自的智控中心；各智控中心的信息再汇集到多部门合署办公的运营管控中心，实现对公司总体生产运营的调度。“部门之间协调联系，以前每天要打三四百个电话，现在点点鼠标就解决了。”马钢制造管理部生产管理室高级经理孙朝泰说。
在多年的一线工作中，冷轧总厂1720酸轧作业长杨涛练就了一手绝活——不用眼看，只听声音，就能知道哪里出了故障。“钢铁切角时，如果发出‘咣当’的落地声，就是正常运转；轧制板带时，如果声音突然变大，就会立刻警觉。”进入智控中心后，杨涛的工作是远程操作，只要在电脑里输入工作参数，产线就可以正常运行。耳边突然安静下来，杨涛甚至一度有点手足无措。
随着对操作的熟悉，杨涛发现，减少了人工干预后，不仅轧制效率显著提高，钢材质量也更稳定。数据佐证了他的这一感受：技改当年，马钢各产线打破日产纪录156次，打破月产纪录46次。2023年，各产线打破日产纪录162次、月产纪录69次。
The transformation to intelligent manufacturing not only focuses on improving production efficiency, but also focuses on improving the quality of workers.

“3年多来，马钢一线岗位平均每年减少约8%，车间里几乎不再有纯粹的体力活。每一名员工都需要向技能型人才转变，成为既懂工艺又懂计算机的复合型人才。”杨兴亮说。
智控中心建成后，冷轧总厂的基层单位由19个整合为8个，作业区由81个优化为42个，接下来的改革就是由“一线三岗”改为“一线一岗”，也就是一条产线从以前3人至4人操作改为只由1个人操作。这样做的目的是实现纵向到底、横向到边的岗位融合，为打造“黑灯工厂”打下基础。
“必须掌握从入口到出口的所有操作要领，发生异常时还要能合理调度现场。”杨涛开始时感到“压力山大”。为了帮助员工尽快成长为适应智能制造的人才，马钢开展了密集的高强度培训，帮助一线员工掌握技能。杨涛等一批年轻人通过培训，拿到了上岗证。
“随着一线劳动强度降低，员工的主动意识、创新意识越来越强。”马钢交材轮轴开发工程师翟龙说，在集团岗位创新创效比学赶超中，他所在的车间仅有23人，一个月就提出了231条改进创新建议。
From the impression of being stupid and rough, to the reality of being specialized and innovative, the steel industry is becoming more and more attractive to young people. 宛佳旺2019年刚参加工作时，同一批入职共3名员工，几个月后就有一个人“跳槽”了。“生产线上的工作重复性较高，年轻人怕干这个没前途。”宛佳旺说，“随着智能化改造的推进，一直有新的挑战、新的学习，工作变得更有吸引力。”入职几年来，宛佳旺已经从一名普通的轧机调整工成长为新特钢精整作业区作业长，负责协调4个工作区域，管理近百人，肩上的担子重了，步履反而更加轻盈。

04 Green blend:Drink Yangtze River water together

Trains pass through the city, which is summarized by foreign tourists as a "strange thing" in Ma 'anshan. On the streets in the center of the city, a train sometimes passes slowly. It is a railway transporting Ma Steel between the factory area and the Kuangqu. The whistle sounded gently, like a silk thread, connecting the inseparable connection between the "urban steel mill" and the "steel mill city".
Less than 10 kilometers east of Ma 'anshan City, you will arrive at the Aoshan Geological and Cultural Park located in Xiangshan District. A large word "source" is engraved on a piece of natural iron ore on the top of the mountain, which condenses the history of Ma 'anshan's development of steel due to mining and the establishment of a city due to steel. The three "general battles" in the 1970s turned the Aoshan stope into a "Magang Granary" with an annual production capacity of 6 million tons, and successively contributed more than 200 million tons of high-quality iron ore until the mine was closed in 2017. In recent years, the "general battle" of environmental management and ecological restoration has turned abandoned mine pits at an altitude of minus 215 meters into "artificial Tianchi". Under the sunshine, the concave mountain lake is like a piece of jasper, reflecting the surrounding mountains.
"Ma 'anshan and Magang have always been a relationship between you and me and you." Ge Bin, mayor of Maanshan City, said that Masang Group is backed by the Yangtze River, and the factories built one after another once accounted for about 40% of the urban area. The steel industry is an industry that consumes water, consumes electricity, and has large emissions. Energy consumption and environmental problems were once prominent. In recent years, through joint efforts by municipal enterprises, outstanding environmental problems left over from the past have been basically solved.
Looking out from the Guanjiang Platform, you can have a panoramic view of the long river, natural beaches and aquatic forests.
"The people protect the Yangtze River and the Yangtze River benefits the people." General Secretary Xi Jinping made a scientific conclusion during an inspection of Xuejiawa Ecological Park in Ma 'anshan. "We must deeply grasp and thoroughly implement the new development positioning given to Ma 'anshan by General Secretary Xi Jinping, strive to create a' cabbage heart', and constantly showcase the scenery of 'one river clear water'." Yuan Fang, Secretary of the Ma 'anshan Municipal Party Committee, said.
"At that time, prolific 'industrial grain' was needed by the country; now, protecting the clear water of a river is what the people hope for. Integrating green development into the integrated development of the Yangtze River Delta is the mission of urban steel mills." Ding Yi said that China's steel industry is an important area for practicing green and low-carbon development. In the context of implementing the "double carbon" strategy, whether pollution reduction and carbon reduction can be promoted in a coordinated manner is related to the survival and development of steel companies. As an urban section steel factory located in the "heart of cabbage" in the Yangtze River Delta, Masteel must shoulder its responsibilities and set an example.

按照中国宝武“高于标准、优于城区、融入城市”的绿色发展要求，马钢结合自身实际，坚持“高站位、高起点、高标准、高颜值”，加速打造花园式滨江生态都市钢厂。
Subtract from the increment to achieve "zero emission of wastewater, ultra-low emission of waste gas, and no delivery of solid waste." 事实上，马钢自身的绿色转型已是箭在弦上。2020年以来，马钢制定了三年规划，累计投入近百亿元，实施了198个“三治”项目。“港务原料总厂原料大棚改造15亿元，炼焦煤筒仓改造11.7亿元，脱硫脱硝改造项目约10亿元……”马钢能源环保部高级主任师顾厚淳掰着指头算账。
2022年初，马钢自我加压，决心全面提速完成超低排改造、加快环保绩效“创A”。
这是又一场背水一战。初步对照梳理，马钢超低排放改造涉及有组织、无组织、清洁运输、监测监控各类项目130多个。当时马钢厂区正在进行“北区填平补齐、南区产线升级”的结构调整，还要在落实疫情防控的要求下边生产、边改造，难度极大。
“现场部分产线、装备已经老化、腐蚀、积垢，治理难度极大。”马钢能源环保部副部长王强说，困难和堵点不是零星半点，但再难也得咬紧牙关上。
时间只有1年。动员大会开过，马钢创A一起步就进入冲刺状态：签订责任状，强化问责；倒排工期，挂图作战；百日攻坚，劳动竞赛。
“当时马钢清洁运输比例不到60%，与创A要求的80%标准存在很大差距。”运输部清洁运输项目人员坦言，通过调整原料运输方式、淘汰更新车辆设备、对车辆排放进行管控，以及仓储封闭式管理等，将“清洁运输+纯电运输”比例提升至84%。马钢成为全国第一家跨区域、跨单位完成清洁运输评估的钢铁企业。
Add the stock and "make green" while "manufacturing green". 以废钢为原料的电炉短流程炼钢工艺因节约能源、减少排放，是中国钢铁行业近年鼓励发展的方向，但烟气处理一直是个“老大难”问题。电炉冶炼时产生的烟气温度高达1100摄氏度，用传统的水淋冷却等方法降温除尘，成本高、能耗大，还避免不了污染。
马钢请来多位专家“会诊”，对多种技术线路调研后，决定采取余热回收方法，通过管道把高温蒸汽输送到RH真空精炼炉里，余热作为资源实现了直接利用。“不光是省下了大量冷却用水。以前用蒸汽需要花钱买，现在除了自用还有富余，可以供给其他钢厂，这项改造每年可以产生约4000万元的经济价值。”马钢能源环保部首席工程师程黄根说，这意味着马钢电炉能耗达到国内领先的“负能量”水平。
记者在园区看到，路边所有照明灯都换上了LED灯。马钢还把所有自有厂房的屋顶都装上了光伏发电板，装机容量达到40兆瓦，每年能产生大约3500万千瓦时电量。“2023年，马钢参与绿电交易量达2.9亿千瓦时，连续两年交易量居安徽省首位。”马钢集团党委宣传部杨旭东介绍，2024年马钢光伏装机容量预计再增加30兆瓦，力争发电量接近7000万千瓦时。
Integrated industry and city,"green" is the bottom line. 2023年5月26日是个值得纪念的日子：作为安徽省内首家完成A级创建钢铁企业，也是中国宝武第一家长流程企业全部完成超低排公示并创A的一级子公司，马钢超低排放改造和评估监测进展情况获得通过，全面完成环境绩效A级企业创建工作。与2019年相比，颗粒物、二氧化硫、氮氧化物排放总量分别降低57.14%、47.73%、63.64%。
“马钢创A成功，争取到信贷融资、差别化电价等方面的政策红利，拓展了企业发展空间，‘省’出来的能耗指标，也为马鞍山市大项目落地创造了条件。”马鞍山市投资促进中心副主任刘军说。
市民们更看重的是，马鞍山市空气质量改善幅度连续位居全国前列，还成功入选首批国家系统化全域推进海绵城市建设示范城市。
Industry and city integrate, and "green" is the background color. 2022年8月，国家3A级旅游景区马钢工业旅游景区正式开园，游客们慕名而来，开启工业景区之旅。这是一场钢厂和城市的双向奔赴。
幸福大道、孟塘园、六汾河……在马钢厂区里穿行，一步一景。按照“把盆景变风景，把景点变景区”的标准，马钢将花园工厂建设“升格”为景区建设，对绿化区域整合优化、美化提升，总面积1300多万平方米的马钢厂区绿地率达到35%，做到“春有花、夏有荫、秋有果、冬有青”，成为市民的打卡地和“会客厅”。2023年10月，马钢3A级景区成为国家工业旅游示范基地。
在长三角一体化发展的潮流中奋勇争先，在高质量发展的道路上开拓进取，马钢一马当先，蹄疾步稳。
