摘　　要：介绍了熔模铸造水玻璃工艺转型升级,实现熔模铸造硅溶胶快速制壳批量应用。该工艺从模料与制壳材料选取、快干剂添加、在线快速制壳、蒸汽脱蜡及蜡料回收处理等工序进行优化升级,彻底消除了水玻璃、盐酸、氯盐等污染物的使用,实现了酸雾、钠盐的零排放。This article focuses on the transformation and upgrading of the process of investment casting water glass to achieve the batch application of fast silica sol shell making in investment casting. The processing technology is optimized and upgraded from the pattern material and shell material selection, fast drying agent addition, on-line rapid shell-making, steam wax removal and wax recovery treatment process and so on, and completely eliminate the use of water glass, hydrochloric acid, chloral acid and other pollutants. Consequently, it achieves the zero emission of acid mist and sodium salt.
