改用硅酸铝耐火纤维毡改炉时,需要粘结剂,由于市售价格较贵,故许多厂都自配磷酸铝粘结剂,但该粘结剂有促进耐火纤维粉化的不良影响,并在高温烘烤时易产生裂纹的缺点,我们做了如下改进。我们尽量减低磷酸铝粘结剂的酸度,将高铝熟料粉与85％的工业磷酸之比,由原来的100:16～18减至100:5,加水调匀,使其充分反应,不再 The use of aluminosilicate refractory fiber felt to modify the furnace, the need for binders, due to the market price is more expensive, so many plants are self-Al phosphate binder, but the binder can promote the adverse effects of refractory fiber powder , And easy to produce cracks when baking at high temperature, we made the following improvements. We try to reduce the acidity of the aluminum phosphate binder, the high alumina clinker powder and 85% of the industrial phosphoric acid ratio from 100: 16 ~ 18 to 100: 5, add water and mix thoroughly to make it fully reacted, no longer
