摘　　要：在直接结合镁铬砖中分别加入不同含量的黄糊精与一定比例的浓缩纸浆混合而成复合结合剂。在相同的制作工艺下,研究这些不同含量复合结合剂对直接结合镁铬砖的物理性能影响。结果表明:在直接结合镁铬砖基质中加入1.5%含量的复合结合剂,与加入2.5%含量、2%含量的复合结合剂以及加入单一的结合剂相比,对直接结合镁铬砖的物理性能影响较好,可以提高直接结合镁铬砖的成型效率和坯体强度。A composite binder is formed by mixing different contents of yellow dextrin and a certain proportion of concentrated pulp into directly bonded magnesium chromium bricks.Under the same manufacturing process,this paper studies the influence of these different contents of composite binders on the physical properties of directly bonded magnesium chromium bricks.The results show that adding a composite binder with a content of 1.5%to the matrix of directly bonded magnesium chromium bricks has a better effect on the physical properties of directly bonded magnesium chromium bricks compared to adding a composite binder with a content of 2.5%and 2%,as well as adding a single binder.This can improve the molding efficiency and body strength of directly bonded magnesium chromium bricks.
