实型铸造锌合金流态自硬砂的研究

A Study on the Properties of Fluid Nobake Sand Used for Full-Mould Casting of Zn-Alloy

通过试验各种因素(水泥含量、水份含量、速凝对加入量和发泡剂含量等)对型砂性能的影响,研制一种不需采用特殊设备和特殊工艺而能较好满足实型铸造锌合金工艺特点的流态自硬砂。

The effect of cement, content,moisture content,addition of speed-hardening agent and foamine agent ou the properties of fluid nobake is studed. The fluid nobake sand is suitable for full-mould casting process.
