Wear mechanism of MgO-MA-C slide plate for casting Ca-treated steel

Keywords： MgO-MA-C slide plate , Ca-treated steel , Corrosion resistance to CaO slag , Wear mechanism

对宝钢试用的镁尖晶石炭滑板进行了性能检测，并与铝炭锆、锆炭质滑板一起进行了抗CaO渣侵蚀试验，其抗侵蚀性优于后者。对用后的镁尖晶石炭滑板进行了显微结构分析，探讨了滑板的损毁机理。

The properties of MgO-MA-C slide plate were tested. Comparative testing of CaO corrosion resistance wascarried out among MgO-MA-C,Al2O3-C-ZrO2 and ZrO2-C materials. The CaO corrosion resistance of MgO-MA-C material was superior to the others. The microstructure of MgO-MA-C slide plate after being usedwas analyzed, and wear mechanism of MgO-MA-C slide plate was discussed.
