摘　　要：研究了Ｆｅ２Ｏ３、ＣａＯ、ＳｉＯ２组分对超高功率电炉偏心底出钢口填充料烧结性能的影响。建立了实验室内模拟填充料使用性能的方法。结果表明处于Ｓ４态烧结的试样适于作出钢口填充料。研制的出钢口填充料在舞阳钢铁公司９０ｔ超高功率电炉上使用，其开浇率好于国外同类产品。the effecrt of Fe2O3, Cao and SiO2 on the sintering properties of filling material for eccentric bottom tapping of UHP EAF has been studied. Five samples have been made for simulation test. The result showed that the sample No.4with moderate sinterability was suitable for being used as filling material which was justified in the practical use in the 90t UHP EAF of Wuyang lron and Steel Co.
