Abstract

PURPOSE: To improve the strength in pouring of molten metal of mold and prevent casting defect owing to casting sand by adding water soluble sodium compound to the binder composed primarily of starch.
CONSTITUTION: A suitable amount of water soluble compound is added to starch glue. Since the binder is made water soluble in this way, there is no need for taking any special means in regenerating the unburned part of the mold and regeneration may be made in exactly the same manner as in conventional regenerating work In addition, the improvement in high temperature strength of the mold may be achieved.
