摘　　要：含钒钛的转炉钢渣对C_固含量12～21%的四种中档镁碳砖渣侵结果表明,铁氧化物在渣侵过程中起主要作用,砖中配入的石墨量愈高,其抗渣侵性能愈强;根据渣侵后镁碳砖的岩相和渣侵前后钢渣成分的变化,阐述了中档镁碳砖的渣侵机理。The result of converter slag erosion on 4 middle grade MgC bricks with Csolid (12～21%) shows that ferric oxides play an important role during slag erosion, and the higher graphite content in the brick is, the better the slag resistance will be. This paper explains slag erosion mechanism of middle grade MgC brick based on petrographic analysis after the slag erosion, as well variation of the slag composition before and after the slag erosion.
