Abstract
PURPOSE: To mold a mold of good collapsing property of high binding forces among refractory materials relatively without evolving any harmful gases during molding and casting by binding the refractory particles relatively by means of the crystal material crystallized from an aqueous soln. of carbohydrate having crystallinity.
CONSTITUTION: Carbohydrate such as cane sugar having crystallinity, and water are mixed in a proper range to prepare an aqueous soln. heated to the m.p. or below of the carbohydrate. This aqueous soln. is added to refractory particles and these are mixed under agitating to prepare kneaded sand. This kneaded sand is put into a molding flask and a mold is molded. When this mold is allowed to stand or is forcibly cooled to temper below of the m.p. of the carbohydrate, the carbohydrate crystallizes while accompanying dehydration, whereby the bending matter is formed and the firm binding of the refractory particles is effected.
