摘要

抚顺特钢与北京科技大学合作在第一炼钢厂1座 50 t EBT电弧炉和 1座 60 t竖式电弧炉上采用USTB(北京科技大学 )炉壁氧气喷吹工艺。使用结果表明

全废钢炉料冶炼周期缩短4.9～7.2 min

废钢 +30 %铁水冶炼周期缩短 9.4～10.9 min

电耗降低17.9～37.2 kWh/t

氧耗增加～4.5m

/t。USTB氧枪的使用寿命达1000炉以上

取得了良好的经济技术效果

Abstract

The USTB(University of Science and Technology Beijing)furnace wall oxygen injection technology have been used for a 50 t EBT arc furnace and a 60 t shaft arc furnace at Nol melting shop at Fushun Steel by cooperation of Fushun Steel and University of Science and Technology Beijing. The application results showed that the tap to tap time re- duced by 4.9~7.2 min with 100% scrap charging and reduced by 9.4～10.9 min with 70% scrap and 30% hot metal charging; the electric power consumption decreased by 17.9~37.2 kWh/t

while oxygen consumption increased by ~4.5 m³/t.The service life of USTB oxygen lance was up to more than 1000 heats to get good economic and technical effect.
