摘要
研究了磷酸铝胶为粘结剂、冶金镁砂为硬化剂的磷酸盐自硬砂，进行了浇注试验。结果表明，该种磷酸盐自硬砂，具有良好的强度及溃散性能，浇注出的铸件质量好。
In this paper the research on non baked sand with aluminium phosphats colloid as binder and metallurgical magnesia as hardening agent was carried out. Pouring experiment have been made, and the result indicats that the phosphats non baked sand has higher tensile strength and excellent shake out property and can produce good quality castings.
