摘　　要：为了增强钢包用铝镁浇注料的抗氧化性能,以高铝料、板状刚玉、镁砂、尖晶石粉、氧化铝超微粉、二氧化硅微粉、炭黑、抗氧化抗侵蚀剂ACAO为主要原料制备铝镁浇注料,实验了增碳剂炭黑及防氧化剂ACAO的配合使用对浇注料各个温度段强度及抗氧化性的影响,分别引入从0到2%的ACAO,以0.5%为差额,等量替代刚玉粉,对制得的试样检测中温1 000℃及高温1 500℃烧后的抗折耐压强度及抗氧化性指标的影响。结果表明:随ACAO引入量的变化,试样烧后线变化率先降低后升高,体积密度先升高后降低,显气孔率变化与体密变化规律相反,通过烧后试样的黑心变化判断,抗氧化性呈现逐渐变好的趋势,当ACAO引入量为1%时,浇注料可以得到最优的综合性能。In order to enhance the oxidation resistance of aluminum magnesium castable for ladle, the aluminum magnesium castables were prepared from high alumina, plate corundum, magnesia, spinel powder, alumina ultrafine powder, silica powder, carbon black and anti-corrosion agent acao.The effect of the combination of carbon black and acao on the strength and oxidation resistance of the castable was tested, The acao from 0 to 2% was introduced respectively, and 0.5% was used as the difference, and corundum powder was replaced by equal amount.The effect of the test sample on the flexural strength and antioxidant index of the samples after being burned at 1 000 he aca 1 500 ifference, and corundum powder was replaced by equal amount.th the change of acao, the change of the line after burning decreases first and then increases, the volume density increases first and then decreases.The change of apparent porosity is opposite to the change of bulk density.Judging from the black center change of the sample after burning, the oxidation resistance is becoming better gradually.When the amount of acao is 1%, the castable can get the best comprehensive performance.
