SALT CORE FOR CASTING LIGHT-ALLOY CASTING, METHOD FOR MANUFACTURING SALT CORE, AND METHOD FOR PRODUCING LIGHT-ALLOY CASTING

摘要

PROBLEM TO BE SOLVED: To provide a salt core for casting a light-alloy casting which is easily removed from a casting and necessitates no post-treatment such as shot blast, sand blast, or spraying of high-pressure water, to provide a method for manufacturing the salt core, and to provide a method for producing a light-alloy casting which is cast by using the salt core.;SOLUTION: The salt core is a fused salt core, which is used for casting a light-alloy casting such as an aluminum-alloy casting or a magnesium-alloy casting, and which uses a nitrate having a melting point within a prescribed range. There are disclosed the method for manufacturing the salt core and the method for producing the light-alloy casting which is cast by using the salt core.;COPYRIGHT: (C)2005,JPO&NCIPI
