我们车间主要的任务是为电厂生产高锰钢耐磨铸件。过去,采用的铸造工艺是串铸和单相铸造,废品率高达20％,出品率为70％。有时在浇注过程中还会出现因闸不住造成跑钢的现象。为了解决这些问题,我们试图采用了叠砂铸造工艺。通过一段时间的生产实践,证明效果良好。结果 The main task of our workshop is to produce high manganese steel wear-resistant castings for power plants. In the past, the foundry processes used were string casting and single-phase casting with rejects of up to 20% and production rates of 70%. Sometimes in the pouring process will result in running can not stop the phenomenon of steel. In order to solve these problems, we tried to use the sand casting process. Through a period of production practice, proved effective. result
