摘要
以棕刚玉和碳化硅为主要原料、铝酸钙水泥为结合剂,制备出了一种高强度的刚玉碳化硅浇注料。通过优化颗粒级配,调整水泥和复合微粉的加入量,测定试样在各种因素影响下的常温和高温强度。结果表明,研制出的刚玉碳化硅浇注料既具有较高的常温强度,又具有很高的高温强度。
A high strength corundum silicon carbide castable is developed by using brown corundum and silicon carbide as major starting materials and calcium aluminate cement as binder.Through optimizing grain composition and adjusting the adding amounts of cement and composite micropowder,the cold and high temperature strengths of sample which is affected by various factors are determined.The result shows that the developed corundum silicon carbide castable not only had a higher stength at normal temperature,but also possesses a very high hot strength.
