作者在水玻璃砂改性与清砂工艺改进相结合的基础上,试验出湿法清砂工艺——水浴清砂。这种清砂方法可使铸件在300℃左右入水清砂,达到了铸件既清砂干净又没有裂纹产生,从而解决了水爆清砂因铸件入水温度偏高易产生裂纹、入水温度偏低清砂不干净的问题。文中列出了水浴清砂后的铸件质量情况,并与水爆清砂法的结果做了对比。 Based on the combination of sodium silicate sand modification and sand removal process improvement, the authors tested the wet sand cleaning process - water bath sand removal. This sand-cleaning method can make the casting water into the sand at about 300 ℃, reaching the casting clean sand both clean and no cracks, thus solving the water blasting sand casting due to high water temperature is prone to cracking, water temperature is too low, clear sand Not clean problem. The article lists the water bath after sand casting quality, and with the result of water blasting sand made a contrast.
