河钢工业技术为“全球首例”注入2800立方米“绿氢”
近日，河钢工业技术服务有限公司（下称河钢工业技术）通过对加氢关键装备和氢冶金核心区工艺联锁系统的研发，为河钢全球首例120万吨氢冶金示范工程一期氢冶金生产注入2800立方米“绿氢”，助其加速实现全绿氢近零碳氢冶金生产目标。

It is reported that the first phase of HBIS's global pioneering 10,000-ton hydrogen metallurgy demonstration project is the first instance to achieve large-scale and stable production of "green steel" through "hydrogen replacing coal" smelting. The project uses coke oven gas as the gas source and has reserved the function for switching to "green hydrogen" in the hydrogen-based shaft furnace reactor.

To promote the development of hydrogen metallurgy technology at HBIS, HBIS Industrial Technology actively advances work on hydrogen production, hydrogen-related equipment manufacturing, and core technology development, making hydrogen metallurgy gas sources greener and continuously enriching the comprehensive application scenarios of new energy hydrogen. HBIS Industrial Technology has proactively taken on the research topic "Research and Application of Key Hydrogen Injection Technology in Hydrogen Metallurgy" from HBIS, fully leveraging the role of the innovation center, resulting in a final percentage of "green hydrogen" in the hydrogen injection process reaching 100%. This has further enhanced the green and clean nature of the hydrogen metallurgy process, significantly advancing the technological sophistication of HBIS's hydrogen metallurgy, and playing a leading role in technological demonstration.

In addition, HBIS Industrial Technology actively explores multiple hydrogen production pathways, leveraging the rich by-product hydrogen advantages of HBIS, and increases efforts in the research and development of diversified hydrogen production technologies. The focus is on tackling key technologies in "distributed low-cost hydrogen production" and "large-scale low-cost 'green hydrogen' production" to achieve efficient and low-cost hydrogen production, providing high-cost-performance hydrogen resources for the hydrogen energy industry.

本报讯 （记者罗忠河）5月24日，《中国冶金报》记者从中国宝武太钢方面获悉，青海亚洲硅业半导体有限公司（下称亚洲硅业）5月初向太钢发来感谢信，感谢太钢为我国首台（套）国产化光伏多晶硅核心装备冷氢化反应器准时成功投产做出的突出贡献。

It is reported that in the month of the year, China's first set of photovoltaic polysilicon core equipment, the cold hydrogenation reactor, was successfully and safely put into operation on time at Asia Silicon Industry, using entirely domestically produced materials. This achievement marks a transformation from reliance on imports to domestic self-supply, making it a milestone event in the construction of China's clean and renewable energy industry, and holds strategic significance for promoting the development of the new energy industry. As of now, the equipment has been operating smoothly.

Today, the photovoltaic industry has become a pillar of China's new energy sector. China's photovoltaic industry has maintained global leadership for many years in terms of technological capabilities, power generation, and installed capacity, with a broad market outlook. The demand for key materials in photovoltaic conversion, such as polysilicon, has also surged rapidly. As market competition intensifies, the core equipment for polysilicon production, the cold hydrogenation reactor, is evolving towards larger size and higher parameters. This development necessitates the rapid large-scale supply and upgrading of key materials, such as iron-nickel-based alloys, with requirements for greater thickness and single weight.

For a long time, the polycrystalline silicon core equipment reactor has relied on imported iron-nickel-based alloy wide and thick plate materials, which have been constrained by small specifications, high costs, and long delivery cycles, becoming a bottleneck in the development of the polycrystalline silicon industry, urgently requiring localization. The customer not only demanded stringent performance requirements such as high temperature resistance, high pressure resistance, strong corrosion resistance, and extremely high surface quality for this product, but also unprecedented requirements for thickness and plate weight, presenting extraordinary technical challenges. Domestic steel mills had never before supplied such products.

In the first half of the year, Taiyuan Iron and Steel (TISCO) took on the mission of achieving localization and large-scale supply breakthroughs in key materials for the photovoltaic industry. Through arduous technical efforts, TISCO boldly adopted an efficient short-process technology route, resolving a series of technical challenges in the production of wide and thick plates made from iron-nickel-based alloys. This led to significant innovations in the production process, allowing TISCO to independently develop high-performance, high-quality wide and thick plates, which were successfully mass-supplied in the same year. Subsequently, in response to the upgraded material selection requirements for polysilicon projects, TISCO achieved a global first by producing alloy wide and thick plates weighing over 100 tons, filling a market gap.

In the month and year, the research and development project won the first prize of the Metallurgical Science and Technology Award from the China Iron and Steel Industry Association and the China Metal Society; in the same month and year, it was also nominated for the "Prize" Annual Innovation Award by the World Steel Association for the year (the 10th session).

In recent years, Pangang Group of Ansteel has implemented a series of assistance projects, planting chili peppers in demonstration bases. The yield per mu of chili peppers can reach over kilograms, with a total output value of about ten million yuan. This represents an increase of yuan per mu compared to traditional corn cultivation, not only optimizing the industrial structure of the village but also significantly enhancing the income levels of the villagers.
