摘　　要：采用真空感应炉浸棒法,在真空度为5 kPa,于1 650℃保温25 min的试验条件下研究了w(C)约为10%的MgO-C材料的抗熔渣侵蚀性;对试验后的试样进行观察与测量,并用SEM分析了侵蚀后试样显微结构。结果表明:在本试验条件下,熔渣的侵蚀速率大于MgO与C反应的脱碳速率,随着CaO-SiO2渣系碱度的提高,MgO-C材料侵蚀量减少;MgO-C材料对CaO-Al2O3熔渣有较强的抗侵蚀性。The slag corrosion resistance of MgO-C material with 10% carbon was researched by bar immersion method in a vacuum induction furnace at 1 650 ℃ for 25 min with vacuum degree of 5 kPa.The specimens after corrosion test were observed and measured and the microstructure was analyzed by SEM.The result shows that the corrosion rate of the molten slag is higher than the reaction rate between MgO and C;as the slag basicity increases,the corrosion to MgO-C material decreases;MgO-C material shows better slag resistance to CaO-Al2O3 slag.
