摘　　要：利用扫描电镜、能谱对RH插入管用后浇注料进行了结构分析,分析了RH插入管用浇注料的侵蚀机理:RH熔渣与插入管浇注料基体相互作用,产生的低熔点物相进入熔渣使插入管产生溶蚀;而高熔点物相粘结在插入管表面造成粘渣。The structure of Al2O3-MgO castable used in RH immersion tube was analyzed by using Scanning Electron Microscope and Energy Dispersive Spectrometer. The present study analyzed the destruction of Al2O3-MgO castable used in RH immersion tube. The low melting pointphases, which were generated by the reaction between the molten slag and RH immersion tube castable, melted into the slagand lead to corrosion of the RH immersion tube, while the high melting point phases built up onto the RH immersion tube.

关 键 词：RH插入管 Al2O3-MgO浇注料 侵蚀
