Abstract
PURPOSE: To casting sand which comprises adding and mixing the rye starch having been subjected to α-conversion while attached with epidermis as an auxiliary binder in the specific weight ratio range and which has the effect of preventing the occurrence of "pull down" and "scab" phenomena.
CONSTITUTION: The casting sand is produced by adding and mixing the rye starch which has been subjected to α-conversion while attached with epidermis as an auxiliary range within a range of weight ratios 0.5 to 3.5% to the casting sand having ordinary compounding composition. The use of this casting sand at the time of producing casting molds in the case of casting sand castings enables the occurrence of "pull down" and"scab" phenomena which are considered typical defects of sand castings to be prevented.
