高效低成本洁净钢平台生产实践

以"冶金流程工程学"为指导,叙述了首钢京唐钢铁联合有限责任公司钢铁厂主体工序高效低成本洁净钢平台的功能解析与铁-钢-轧界面技术。钢铁厂投产运行两年来,总体运行情况良好,实现了工序流程最优化,"全三脱"比例稳定在80%以上;加快了物质流动速度,实现日产钢90炉;降低了能量损失,出钢温度大幅降低;各种物耗降低,副原料和常规比降低30%以上。

High efficiency low cost platform for clean steel production practice

According to the theory of "metallurgical process engineering",the present paper described analysis on the function of the high efficiency and low cost production,platform for clean steel and iron-steel-HR interface technology of the main processes of Jingtang Iron and Steel Plant.The Plant has been running very smoothly as a whole for two years since being put into commissioning and the purpose of process optimization realized as well.Total De-S,De-Si,De-P ratio steadily maintains on above 80 % and in the meanwhile the material flow rate is also accelerated and the target of 90 heats per day realized,energy loss reduced,tapping temperature lowered markedly and all kinds of material consumption reduced dramatically.In comparison with the normal level the consumption of the auxiliary material is reduced by 30 %.
