摘　　要：本文主要讨论了硅微粉及α-Al2O3微粉对抗铝浇注料施工性能、成型性能及强度的影响。结果表明:(1)基质中单独引入硅微粉时,随着硅微粉加入量的增加,抗铝浇注料的用水量减少,施工性能得到改善;随着硅微粉含量增加,试样的体积密度逐渐上升,烘干及烧后高温烧后强度升高,烧后线变化逐渐下降;(2)基质中引入硅微粉和α-Al2O3的复合粉,随着二者比例的增加,抗铝浇注料的性能不断得到改善;本试验中,当基质中硅微粉占4%,α-Al2O3占1%,此时加水量、成型性能、强度、线变化率最优。： Thi anti -aluminum bulk density, s paper deeply studied the effect of microsilica and alumina powder on the properties of castable. The results show that properties such as water addition, construction properties, strength before or after fired and reheat liner change all can be improved with the microsilica content increased. When the composite powder were added in the matrix, properties of the anti-aluminum tastable can be improved with the ratio of silica and alumina powder, expecially when the microsilica was 4% and alumina powder was 1% , the properties were optimum.
