| 摘 要： | 对基质组成不同的矾土基高铝－尖晶石质钢包浇注料的流动性、升温过程中的脱水行为、物理性能、抗热震性、抗渣性、显微结构等特性进行了研究。结果表明，采用ＳｉＯ２超细粉形成ＭｇＯ－ＳｉＯ－Ｈ２Ｏ系的凝聚结合，不但可改善浇注料的流动性，获得高密度和强度，而且生成合结晶水很少的凝胶，改善了浇注料的烘烤性。基质组成的不同对浇注料的加水量、流动性和抗烘烤爆裂性的影响不大，但导致烧后物理性能、热震和抗渣性能有差异。

| Abstract: | The characteristics including flowability,dehydration behavior during heating, physical properties,thermal shock resistance,sing resistance and microstructure were investigated in relationship with the matrix competion of the castables.Improved flowability, high density and strength are attributed to the adoption of microsilica which reacts with MgO and H2O to form magnesium-silicate-hydrate (M-S-H) gel.The variation in matrix commpition has little influence on water addition, probability and explosion resistance,but results in some difference in physical properties, thermal shock resistance and slag corrosion and penetration. |
