摘要/Abstract

摘要： 通过本钢特钢厂800初轧机将350mm×470mm碳素和合金钢坯轧制成Φ210mm棒材的孔型由圆-大椭圆-箱-平箱系统替代原有的圆-扁八角-平箱系统,并优化压下制度,使轧制的合格率达99.75%。

Abstract: With round- large oval- box- flat box pass system to replace original round- flat- octagon- flat box pass system,and optimized reduction schedule to roll φ210 mm carbon and alloy steel bars from 350 mm×470 mm bloom by 800 blooming mill at Special Steel Works, Bensteel, the qualified rate of rolled steel products was up to 99.75%.
