Abstract

PURPOSE:To improve the workability by mixing binder with fossilized shell powder forming the specific grain size of sandy layer or material adding and blending refractory powder to the shell powder and burning a molded mold at the prescribed temp. CONSTITUTION:The mold is made by mixing the binder with the fossilized shell powder forming the sandy layer having 10-400 mesh grain size or the material adding and blending >=7% the fossilized shell powder to the refractory powder of silica sand, chamotte, fused silica, zircon, etc. Next, the mold is burnt at >=760 deg.C. By such constitution, the collapsibility is improved and the workability is improved.
