摘　　要：以特级高铝矾土为骨料,同时加入特级高铝矾土粉、棕刚玉粉、CA-50水泥、二氧化硅微粉及Cr2O3粉,检测其气孔率、体积密度、抗折强度、耐压强度、线变化率以及抗渣性。最后经过实验得出结论:当SiO2微粉含量为5%时气孔率最低,体积密度最高;当CA-50水泥含量为5%时抗折强度、耐压强度、体积密度最高、气孔率和线变化率也低;SiC骨料和细粉比例为4∶6,气孔率较小,体积密度比较大,强度相对较好。从抗渣性实验的结果可以看出,加入不同比例的SiC骨料和细粉,能提高其抗渣性,进而降低成本,提高炉衬寿命。This paper describes a high - grade bauxite for the aggregate, to join the CA - 50 cement, high - grade bauxite powder, brown fused alumina powder,microsilica and chromium micropowder. Testing the castable refractory nature the kadlo furnace liner to the permanent liner change rate, flexural strength, pressure strength, bulk density, porosity and the effect of slag resistance. After the finally test analysis concluded that when adding mlcrosilica 5%, porosity is lowest, bulk density is highest. When adding CA - 50 cement 5% ,flexural strength, pressure strength, bulk density porosity are highest, porosity and permanent liner change rate are lowest. Sic aggregate/powder is 4/ 6, improve property of slag resistance. Thereby reduce production costs and increasing the life of furnace liner.
