Abstract: With using magnesitc-calcium brick as lining material of 45 t AOD refining units at Taiyuan Steel to replace magnesite-chrome brick,establishing available AOD line baking procedure,shortening refining time,and controling slag basicity CaO/SiO₂=1.8~2.0,(CaO+MgO)/SiO₂=2.0~2.4,the 45 t AOD lining life has been increased to 189 heats from 50 heats.

摘要: 通过采用镁钙砖取代镁铬砖作为太钢45 t AOD精炼炉的炉衬材料,制定合理的AOD炉衬烘烤制度,缩短精炼时间,控制炉渣碱度CaO/SiO2=1.8~2.0,(CaO+MgO)/SiO2=2.0~2.4,使45 t AOD炉龄由50炉次提高到189炉次。
