中间包永久衬浇注料用结合剂

以B级高铝矾土熟料为骨料，A级矾土熟料为基质料，同时加入蓝晶石、硅线石为膨胀荆，紫木节粘土为烧结剂、塑化剂，研究了分别采用硅灰、高铝水泥、水玻璃、复合结合剂等为结^合剂的不同配方组成的浇注料。通过浇注料试样性能检测比较，探讨了不同种类结合剂对浇注料性能的影响，实验证明复合结合剂更有利于浇注料性能的提高。

The Binder of Castable Permanent Lining of Tundish

Using B Grade bauxite as bone material and A Grade bauxite as powder,different binder composition castable for permanent lining fo fundish were studied,with cyanite and sillimanite as expansion additives and Zimujie clay as sinter additive and plastic additive.The binders were as follows:silicon ash,aluminated cement,sodium silicate and composite binder.The effects of different binders on the castable were discussed by the comparison of castable samples properties from testing results.The experimental results show that the composite binder is more useful to improve performance of the castable.
