摘　　要：介绍了甲酸甲酯硬化水玻璃工艺的开发工作，综合论述了该工艺的硬化原理、工艺性能、相关设备和目前的应用情况，并与三乙胺工艺作了对比。认为在铸件综合成本、抗裂纹、环保等方面有巨大优势，若同时使用酯硬化水玻璃或碱性树脂工艺做外型，其旧砂的回用性更有着无可替代的优势，对再生砂不产生任何影响。认为该工艺在现有技术水平上已完全达到推广应用的阶段．The methyl formate hardening water glass process was developed, including the hardening mechanism, process properties and equipments. Comparing to triethylamine cold box process, the water glass process has certain advantages in cost, environment protection and reject rate （such as cracks）. The reclamation of sand can be improved further if the process used with ester hardened water glass sand or alkali resin sand for moulding sand. The process can be used for casting process more widely.
