在学习兄弟单位经验的基础上,我厂采用了铸铁件水爆清砂工艺。目前,已有普通铸铁、合金铸铁的240余种零件实现了水爆清砂,大大提高清砂效率,改善劳动条件,深受工人同志们的欢迎。现将生产情况作如下介绍,供参考。铸件入水温度和型芯温度铸件入水温度高,裂纹大,水爆效果不一定好。相反,铸件入水温度适当,则不易发生裂纹,水爆效果较好。铸件水爆不是本身的温度引起,而是 Based on the experience of our brother units, our factory has adopted the blasting sand blasting technology of cast iron pieces. At present, more than 240 kinds of parts of ordinary cast iron and alloy cast iron have realized waterblasting and clear sand, which greatly improves the efficiency of sand cleaning and improves working conditions, and is highly praised by the workers. The production is now presented as follows for reference. Casting water temperature and core temperature Castings into the water temperature is high, cracks, water explosion effect is not necessarily good. On the contrary, casting water temperature is appropriate, it is not easy to crack, water burst effect is better. Casting water burst is not caused by its own temperature, but
