摘要

以安钢150 t转炉炼钢数据为计算依据

进行了物料平衡和热平衡计算

并建立了计算模型。方案优化后

对其物料及热平衡进行了多次循环测算

从而得到合理的炉料结构配比

热平衡钢水物理热和炉渣物理热约占总热量支出的75%

废钢物理热支出占总热量支出的6%～7%

当废钢比为7%～10%时

钢铁料消耗降低了5.9 kg/t

钢

约节省生产成本26.14元/t

钢

。

Abstract

Based on data of 150 t converter steelmaking at Anyang Steel

the calculation of charging material balance and heat balance have been carried out and a calculation model is established. With optimum scheme

the multi - cycles calculation on the charging material and heat balance has been carried out to get a reasonable ratio of charging structure

the physical heat of heat balance of liquid and slag making up 75% of total heat expenditure

the physical heat of scrap making up 6% ~ 7% of total heat expenditure

and with the crap ratio being 7% ~ 10%

the consumption of iron and steel charging material decreases by 5. 9 kg per ton of steel and the production cost reduces about 26. 14 Yuan per ton of steel.
