摘要
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。
Eligible rate of bloom in Laiwu Steel was increased to about 99.92% by strict control of moisture in the raw materials, application of catch carbon operation at the end point of BOF, constant speed during continuous casting etc. Stronger managements between steelmaking and roll and co-ordination among different units were realized by adjustment of the supply plan of steel. Defects in billets were reduced by billets carrier with insulation caps, application of burial pits, slow cooling caps and so on. Billets can be hot charged which can decrease heating energy of about 0.34 GJ/t and with a saved cost about 7.8 million RMB per year.
