Abstract

PURPOSE:To securely bond refractory particles to each other at the time of molding so that the embrittlement of the surface of a molded casting mold is eliminated by coating a surtactant on the surface of the refractory particles, coating a binder thereon and packing such particles into the mold. CONSTITUTION:The refractory particles of silica sand, etc., are stirred and mixed by an aq. surfactant soln. to coat the surfactant thereon and the binder is coated thereon. The binder prepd. by adding an alkali salt contg. water of crystallization of sodium phosphate, potassium phosphate, etc., to water glass and heating and dissolving the mixture to a liquid state is used as the binder. This coated sand is packed into the mold kept at a prescribed temp. and the binder is redissolved at the mold temp., by which the water of crystallization in the sand mixture is evaporated away and cured. The coated sand mixture in a thoroughly dry state so that the sand can be packed into the mold by air blow. The accuracy of the casting mold having intrucate shapes is thereby improved and the mold is produced while the surface strength is assured.
