摘　　要：介绍了湿型砂各组分的作用,论述了型砂性能与其组分的关系,认为控制好有效膨润土量和有效添加剂量是控制型砂质量的关键,结合生产实例说明了型砂质量的控制要点;指出提高型砂质量控制水平、生产优质铸件和实现铸造生产循环用砂是铸造生产节能减排的根本方法之一。The effects of various ingredients of the green molding sand were introduced. The relationship between properties of the molding sand and its ingredients was described. It was considered that correct controlling the active bentonite amount and its addition amount is the key measure to control the quality of molding sand. By showing practical example, the key points of molding sand quality control were explained. It was pointed out that elevating the quality control level of molding sand to produce high quality castings and actualize sand cycling usage in foundry production is one of the radical methods to conduct energy saving and emission reducing in foundry production.
