摘　　要：以高铝水泥、SiO2微粉、活性α-Al2O3微粉作为影响铝硅质低水泥中间包永久层浇注料性能的主要因素,采用正交设计法,制成9组试样。每组试样于110℃烘干,经1550℃烧成后,检测其烧后线变化、显气孔率、体积密度、抗折强度、耐压强度及抗热震性等物理性能指标。结果表明,最优配方为A2B2C3,即三种原料各加入4%。Regard high alumina cement、SiO2 powder、reactive α-Al2O3 powder as the main factors to function the permanent layer of castable in tundish.Adopts orthogonal design,make into 9 groups of samples.Each samples drying at 110℃ and sintering at 1550℃ relatively,then to measure the linear change of after firing,apparent porosity,bulk density,modulus of rupture,compressive strength and thermal shock resistance equal physical properties.The result indicates that the optimal formula is A2B2C3,it means that quantity of the three raw materials is 4% respectively.
