转炉生产45#钢的工艺实践

主要介绍了炼钢厂采用“80吨转炉＋LF精炼＋连铸”生产45#优质碳素结构钢的工艺实践，对莱钢实现品种结构调整具有重要意义，实现了公司将45#钢由电炉系统向转炉系统转移的目标，达到了降本增效的目的。

This paper mainly introduces the practice of the production of No, 45 high-quality carbon structural steel with the process of ＂ 80t LD ＋ LF ＋ CC＂ in the Steelmaking Plant, which is significant for Laiwu Steel to realize grade structure adjusting for it has realized the target of transferring No, 45 steel smelting from in EAF system to in LD system, attaining the aims of cost reduction and profit increment.
