对使用型砂添加剂替代煤粉的新工艺进行了试验研究,并在进口的CF气冲造型线上试用,取得了良好的效果。这种型砂添加剂能改善型砂性能、降低铸件废品率、并能极大限度地改善铸造车间的工作环境。
The use of sand additives to replace the pulverized coal new technology were studied and imported CF blow molding line on the trial, and achieved good results. This sand additive can improve sand performance, reduce the casting scrap rate, and can greatly improve the working environment of the foundry.
