摘　　要：研究结果表明：转炉初期渣使MgO-C砖产生结构利落，因而蚀损最严重；但对MgO-CaO-C砖的侵蚀较轻，这是因为在砖的界面上产生了C2S保护层。中期和终期渣对MgO-CaO-C砖的侵蚀由于其更易于被渣中ΣFeO溶解，所以比MgO-C砖要强烈些。Erosion of initial slag to MgO-C brick is the worse damage led by structural spalling. But to MgO-CaO-C brick,the damage is not all serious because of a C2S layer formed on the interface of the brick. Erosion of mid and final slagsto MgO-CaO-C brick is stronger than that to MgO-C brick because the former is easily cornded by ΣFeO in the slags.
