摘要： 本工作针对钢铁行业副产的煤气、余热、钢渣及钢化联产现状进行了分析，论述了碳中和背景下钢化联产绿色低碳技术的发展趋势，展望了未来无碳炼钢的新型钢厂从“以化固碳”转变为“以氢代碳”的新模式，并提出了加快钢化联产新技术应用建议和举措，以期建立以钢铁行业为龙头，耦合化工行业的新型工业可持续发展生态链，支撑我国“双碳”目标的实现。

关键词: 碳中和, 钢铁, 化工, 钢化联产

Abstract: The by-produced gas, waste heat, and steel slag as well as the current situation on the co-production of steel and chemical in the iron and steel industry are analyzed. The developing trend of green and low-carbon technologies is discussed and the new mode from "carbon fixation by chemical" to "carbon substitution by hydrogen" in carbon-free steelmaking in the future is prospected. Suggestions and measures are put forward to the application of new technologies for steel and chemical co-production. It is expected to establish a new sustainable industrial ecosystem with the steel industry as the leader coupled with the chemical industry to support the realization of China's carbon peaking and carbon neutrality goal.

Key words: carbon neutrality, steel, chemical engineering, steel chemical co-production
