This is the official Weibo account of Sinosteel International Engineering Technology Co., Ltd.(Sinosteel International). Listen to the most authoritative voice of Sinosteel International and feel the power of Sinosteel International in continuous innovation and sustainable development.

In the new spring and a new departure, Sinosteel International is leaping forward. Sinosteel Equipment Co., Ltd.(referred to as "Sinosteel Equipment"), a wholly-owned subsidiary, won the bid and signed a technical transformation project for the efficient utilization of refractory iron ore resources of Gansu Jiugang Group Hongxing Iron and Steel Co., Ltd.(referred to as "Jiugang Hongxing"), in order to enhance China's ability to ensure the supply of important mineral resources and promote the high-quality development of the steel industry. New steps have been taken!

International pioneering technology

Double improvement in quality utilization rate

Jiuquan Iron and Steel (Group) Co., Ltd.(referred to as "Jiugang") was founded in 1958. It is the earliest and largest diversified modern enterprise group in Northwest China, with both black and non-ferrous metals. As a listed subsidiary of Jiugang, Jiugang Hongxing owns two mines: Jingtieshan Mine and Xigou Limestone Mine. In order to improve ore utilization, improve the quality of self-produced concentrates, and significantly enhance the consumption capacity of surrounding mineral resources, Jiugang Hongxing refractory iron ore resources technical transformation project came into being. Sinosteel Equipment stood out from the bidding with its leading technology.

根据协议，中钢设备负责为酒钢宏兴new165万吨/年的2#悬浮磁化焙烧炉、并transformation原有1#悬浮炉余热锅炉，工期预计20个月。项目投产后：

Iron concentrate grade increased 12.5%

Iron metal recovery rate 16%

Operation rate reaches 93%

Annual iron concentrate output is about 220,000 tons

Product quality and resource utilization levels have been significantly improved

项目将采用Hydrogen-based mineral phase conversion technology （原称"悬浮焙烧"技术），通过利用氢气等还原性气体作为还原剂，将矿石中的弱磁性铁矿物转化为强磁性铁矿物，实现难选铁矿资源的高效利用，实现低品位矿石到高品位的铁精矿粉的升级蜕变。

作为The world's first new technology for efficient utilization of complex and refractory iron ore，该技术具有氧化焙烧与还原焙烧分离、焙烧温度低、 Large production capacity (single-line production capacity up to 2.3 million tons/year), environmentally friendly and pollution-free, low production costs, high energy utilization efficiency and high degree of automation等突出优势。

中钢设备EPC总承包建设的海南矿业股份有限公司石碌铁矿200万吨/年悬浮磁化焙烧炉项目也using this technology ；截至目前，中钢设备已全面建成该项目的焙烧炉系统工程、并完成单体试车及烘炉工作，获得了客户的高度认可。

Hainan Mining Suspension Magnetized Roaster Project constructed by Sinosteel Equipment EPC General Contract

Iron ore is the "grain" of the steel industry. Strengthening the ability to guarantee iron ore resources and ensuring the safety of the steel industry chain and supply chain are an important part of promoting the high-quality development of the steel industry. Hua Guanglin, executive deputy general manager of Sinosteel International, said:"Sinosteel International relies on its strong technological transformation capabilities to promote the engineering of original technologies, From the Hainan Mining Suspension Magnetization Roaster Project to the Jiugang Hongxing Project, we have allowed leading hydrogen-based mineral phase conversion technology to go out of the laboratory and into the Kuangqu to activate resource advantages for customers. Improve the level of development and utilization of iron ore resources, enhance the ability to ensure the supply of iron ore resources, and make greater contributions. "
