摘　　要：酯硬化水玻璃砂干法再生前必须进行加热烘干。试验表明，加热烘干的最佳温度为３００～３５０℃。再生砂的循环使用会使再生砂的溃散性变差，本文对再生砂溃散性变坏的原因及防止措施进行了分析。It is necessary to heat the ester hardened silicate sand before dry reclamation.The results revealed that the optimal heating temperature is in the range 300～350℃,the cyclic recovery and re use of reclaimed sand resulted in deterioration of collapsibility,in this paper,the cause for deteriorating the collapsibility of ester hardened silicate sand and its preventive measures were also analysed.
