流态砂这项新工艺,我厂是在一九六九年去洛阳矿山机器厂学习的,于一九七○年先后在造芯、造型方面投入了生产。深受广大铸造工人的欢迎,取得了一定成绩。到目前为止,应用这种工艺方法,已生产出各种铸钢阀门和商品件四千余吨。其中,最小铸件五、六公斤,最大铸件达三吨以上,铸件壁厚10~200mm。根据我厂几年的实践,现将流态砂在铸造生产上的应用情况做如下介绍:
Flow sand of the new technology, our factory was in 1969 to Luoyang Mining Machine Factory to learn, in 1970 has in the core, modeling put into production. Welcomed by the majority of foundry workers, and achieved some success. So far, the application of this process has produced over 4,000 tons of various cast steel valves and commodities. Among them, the smallest castings five or six kilograms, the largest castings up to three tons, castings wall thickness 10 ~ 200mm. According to our plant a few years of practice, the application of fluid sand in the production of castings are as follows:
