本文介绍53CaS钢的冶炼工艺及钢包喷粉参数的控制。分析不同冶炼工艺条件下所获得的夹杂物形态及其纵横向性能。 以氩气为载流,利用喷粉罐将Fe_2S粉和Ca—Si粉混合喷入钢包的工艺是试验中较好的一种工艺。当氧化物成颗粒分布时,它们大多被硫化物所包围,有利于切削,而钢材的横向冲击值也有所提高。 This article describes the 53CaS steel smelting process and ladle dusting parameters of the control. The morphology and longitudinal and transverse properties of inclusions obtained under different smelting conditions were analyzed. Argon as carrier flow, the use of powder spray cans Fe_2S powder and Ca-Si powder mixed into the ladle process is a better test of a process. When the oxide particles are distributed, they are mostly surrounded by sulfide, which is good for cutting, and the transverse impact value of the steel is also improved.
