摘要： PURPOSE:To provide a self-curing mold material for casting Ti (alloy) which accelerates curing and improves compressive strength by adding the salts of alkaline (earth) metals as a curing accelerator to aggregate consisting essentially of MgO. CONSTITUTION:A self-curing mold material for casting Ti or Ti alloy is formed by adding >=1 kind among the hydrogencarbonate, carbonate and phosphate of alkali metals and the hydrogencarbonate, carbonate and phosphate of alkaline earth metals, for example, NAHCO3, KH2PO4, etc. as a curing accelerator to aggregate consisting essentially of MgO. A casting mold prepd. by kneading the mold material added with such soluble salts with water is accelerated of the solidification reation and cures in a shorter time and therefore the working stage for producing the casting mold and casting is made more efficient.

摘要： PURPOSE:To provide a casting mold material for microwave heating which is so composed as to permit the uniform hardening over the entire part of a casting mold by coating a binder prepd. by kneading a proper amt. of water glass and alkali salt bound with water of crystallization on the surface of refractory particles such as silica sand. CONSTITUTION:2-5wt% Water glass and alkali salt such as sodium phosphate bound with water of crystallization are mixed with 100 refractory particles such as silica sand and the mixture is heated to melt at about 70-100 deg.C, thereby preparing a liquid binder. The binder and the silica sand heated to about 40- 50 deg.C are kneaded until the sand temp. drops to about
摘要翻译：目的：提供一种用于微波加热的铸模材料，其通过涂布粘合剂制备而在铸模的整个部分上均匀地硬化。通过揉合适当的amt。的水玻璃和碱金属盐结合在难熔颗粒如二氧化硅砂的表面上。构成：2-5重量％水玻璃和碱金属盐如与结晶水结合的磷酸钠与100个耐火颗粒如硅砂混合，混合物在约70-100℃下加热熔融，从而制备液体粘合剂将粘合剂和加热到约40-50℃的硅砂捏合直到砂温。降至约<= 40℃。涂布在硅砂表面上的粘合剂中的水分在该状态下形成结晶水，粘合剂在二氧化硅砂的表面上均匀地固化，从而形成用于微波加热的干模铸造材料。如果使用这种铸模材料，则在加热期间，在模具中没有水沸腾的情况下获得具有高尺寸稳定性的铸模。
