| 摘 要： | 超高功率电弧炉出钢口在使用过程中要经受钢液的冲刷、渣液的侵蚀、氧化和温度的剧烈变化。目前，一般用碳含量10％～20％的不烧MgO-C质耐火材料生产出钢口，但是由于碳含量高出钢口的抗氧化性和抗钢液冲刷性都不能达到满意的效果。为此，研究和开发了低碳MgO-C和Al2O3-SiC-C复合材料的整体出钢口。

| Abstract: | The taphole of UHP-EAF should stand severe molten steel corrosion, slag erosion, oxidation and temperature change during operation. In general, the refractory containing 10 % ~ 20 % carbon is widely used. However, the properties of both oxidation resistance and erosion resistance of high-carbon refractory are not satisfactory. Therefore, a study was carried out to develop a monolithic taphole made of unburnt low-carbon MgO-C in combination with Al 2O 3-SiC-C. |
