转炉优钢铸坯热送技术应用

莱钢通过控制原材料水分、实施高拉碳冶炼操作、恒拉速连铸等,提升铸坯合格率到99.92%;通过调整供钢计划,实施炼钢、轧钢生产时刻联动管理,加强工序协调;采用自动加保温罩系统密闭运坯车,设计使用缓冷坑、缓冷罩等,降低铸坯热量损失。实现了铸坯热送,降低加热能耗0.34GJ/t,年节约能源成本780万元。     

Activity of Reducing Steel Slag of EAF

Reducing steel slag (RSS) was mainly acquired from five electric-arc furnace (EAF) steelmaking plants (among them, the products of two plants were carbon steel and those of other plants were stainless steel) for research tests. The chemical properties, compound compositions, activities and contents of main expansive compounds were tested. The results showed that the field sampled RSS had a very high crystallinity and hydraulicity with main chemical compositions close to those of Portland cement. It can be k...
