【摘要】 以板状刚玉、镁砂、α-Al₂O₃微粉、纯铝酸钙水泥、SiO₂微粉为主要原料,通过高温下的原位尖晶石生成反应来制备MA尖晶石浇注料通过对基质中镁砂、SiO₂微粉、纯铝酸钙水泥等几项基质组分含量的调节,来研究各种组分对耐火浇注料性能的影响。结果表明,以MgO-SiO₂-H₂O为结合体系,镁砂含量为3a%（wt）的新型无水泥MA尖晶石浇注料具有优异的性能。更多还原

【Abstract】 By using corundum,MgO powder,α-Al₂O₃ powder,calcium aluminate cement and SiO₂ powder as main starting materials,MA spinel castable is made in-situ reaction at high temperature.Changing MgO powder,calcium aluminate ce- ment and SiO₂ powder addition in matrix composition,the effect of matrix composition on properties of MA spinel castable was studied.The results show that the MgO-SiO₂-H₂Osystem,3a%（wt）MgO addition,non-cement MA spinel castable has the outstanding properties。更多还原
