宝钢炼钢厂转炉挡渣工艺技术的发展

Development of the Slag-stopping Technology during Converter Tapping in Baosteel Steelmaking Plant

采用转炉出钢挡渣工艺技术控制转炉出钢下渣量,必须关注和解决转炉出钢全过程的下渣控制。评价转炉出钢挡渣效果的关键指标是挡渣成功率和钢包中的渣厚。宝钢炼钢厂转炉出钢挡渣工艺技术的发展,目标是实现转炉出钢全过程的自动判渣和挡渣,提高挡渣成功率,减少出钢下渣量。

When using a slag-stopping technology to reduce the amount of slag into the ladle,operators must pay attention to the roughing slag control in the whole process of converter tapping.There are two key indicators:the achievement ratio of slag stopping and the slag thickness in the ladle.They can be used to evaluate the effect of slag-stopping.The development of the slag-stopping technology for converter tapping in Baosteel Steelmaking Plant aims at the realization of the automatic slag adjustment and slag-sto...
