Replies are encouraged – feel free to discuss! -------------------------------------------------- On December 19, 2022, it was reported by the Publicity Department of Zuoquan County Committee in Jinzhong City, Shanxi Province, that the industrial-scale testing facility for hydrogen-based direct reduction of iron developed by Zhongjin Metallurgy Technology Co., Ltd. in Zuoquan County has successfully completed its full-scale trial production. The CSDRI technology developed by this company fills a gap in China’s technologies for hydrogen-based vertical furnace direct reduction of iron; it is the world’s first system to achieve large-scale trial production using 100% coke oven gas as the fuel source for such processes. Recently, the company successfully produced hot-pressed briquettes that met the required standards, with a daily production capacity of 800–900 tons. The quality of these products meets the requirements for high-grade products as specified in the \"Standards for Direct Reduced Iron Used in Steelmaking,\" and it also complies with the standards for foreign gas-based direct reduced iron products. This successful pilot production marks another milestone achieved by Zhongjin Metallurgy Technology Co., Ltd. in its hydrogen metallurgy technology, which has been under development for over a decade. At present, the company is still carrying out forward adjustments and optimizations to the manufacturing process, continuously refining the parameter requirements for various steps in order to further improve product quality and operational performance.
Based on the pilot production data from hydrogen-based direct iron reduction facilities, compared to traditional blast furnace ironmaking processes, producing 1 ton of reduced iron can reduce carbon dioxide emissions by 50%, while also cutting emissions of pollutants such as sulfur dioxide and nitrogen oxides by 74% and 63% respectively, along with a 20% reduction in energy consumption. To date, the project has produced over 12,000 tons of high-quality reduced iron products. Once it is operating at full capacity, it is expected to generate an annual output value of nearly 1 billion yuan, along with profits and taxes of around 200 million yuan.
