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,并指出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,结合生产实例阐述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有效方法。In this paper, the functions of every component in green sand were outlined and the relationship between properties of mould sand and its component was discussed. It is the key to control content of effective bentonite and additives for mould sand quality. The main points of mould sand quality control were showed by practical production case. Enhancing quality control level for mould sand, producing high quality casting and realizing recycling use of sand in foundry production are effective methods in realization of energy saving and emission reduction of foundry production.
