整体出钢口及挡渣出钢技术的应用

Application of Integral Change of Tap-Hole and Technique of Slag Dammingwith Rolygonal Cone in Converters

攀钢120t转炉通过整体出钢口及挡渣出钢技术的应用,达到了提高出钢口使用次数,稳定出钢时间和出钢温降,减少下渣量和提高合金收得率的效果,为减轻劳动强度、稳定工艺操作、改善钢质量起到了积极作用。

The results of increasing tap-hole life, stablizing tapping time and dropping its tempreture, reducing slagfrom converter to ladle during the tapping and inhancing alloy's producing ration are achieved by the integral changeof tap-hole and the application of slag-damming process with rolygonal cone in 120t converters at Pan Steel.It is ofparticular advange to reduce labor strenthstabilize operation and improve steel quality.
