大型铸钢件散砂控制研究

Study on the Control of Loose Sand in Large Steel Castings

介绍了大型铸钢件型腔内散砂产生的原因,从工艺设计和现场操作两方面,总结大型铸钢件的散砂控制要点,减少铸钢件表面的砂眼缺陷,提高铸件表面质量。

This paper introduces the cause of loose sand getting into the cavity of large cast steel, and from the two aspects of process design and site operation, sums up control points of the loose sand in large steel castings, reducing blowholes on the surface of steel castings, and improving the surface quality of the castings.
