摘要

使用1 t双极电渣炉试验研究了大气条件下酸性渣重熔含硫M35高速钢(0.015%～0.030%S)的成分变化和碳化物、非金属夹杂物的质量水平。酸性渣重熔时

钢锭大小头硫、硅、锰、铬有较大的差值

化渣时添加硫化钙和倒渣时加入锰铁粉

可减小钢锭大小头差值。酸性渣重熔的含硫M35高速钢轧材碳化物不均度、颗粒度质量水平与常规碱性渣系相当

非金属夹杂物A类≤1.5级、B、C、D类≤1.0级。

Abstract

It was studied the quality of carbide

non-metallic inclusions and composition change of sulfur bearing M35 high speed steel (0. 015% ~ 0.030 S) using acid slag remelting in atmospheric conditions using the 1 t double electrode furnace. When the acid slag was remelting

the sulfur

silicon

manganese

chromium have a large difference between the two ends of the ingot

the difference reduced using the method of adding calcium sulfide when slag melting and adding manganese iron when Slag dump. The quality level of carbide nonuniformity granularity of sulfur bearing M35 high speed steel mill bar is similar to that of conventional alkaline slag

non-metallic inclusions class A is less than 1.5

C and D

which are less than or equal to 1.0.
