概论蒸馏制锌需要消耗大量的耐火粘土及其制品:蒸馏罐、冷凝器、异形砖与标准砖。每制一吨锌约需消耗耐火材料一吨。由于对耐火材料制品的要求很高(尤其是对蒸馏罐),而它们远程的运输又会有产生裂缝的危险、因此一般它们都在厂内耐火材料车间内制造。好的罐能用二十五至三十昼夜,此时每制一吨锌的 Introduction Distillation of zinc needs to consume a large amount of refractory clay and its products: distillation tank, condenser, shaped brick and standard brick. One tonne of zinc per unit consumes about one ton of refractory material. Because of the high demands placed on refractory products, especially for retorts, and their long-range transport risks creating cracks, they are generally manufactured within the plant’s refractory works. Good tanks can be used twenty-five to thirty days and nights, at this time each tonne of zinc
