Abstract

PURPOSE: To eliminate the need for ramming, compressing, vibrating, etc. at the molding by mixing the aqueous solution of sodium aluminate of the specified Na2O/ Al2O3 (molar ratio) to refractory sand particles of Al2O3, etc. then pouring the mixture into the casting frame of the pattern to mold the casting mold then allowing the mold to set by CO2.
CONSTITUTION: The aqueous solution of sodium aluminate (e.g., 4Na2O. Al2O3. 10H2O) of the Na2O/A2O3 (molar ratio) having been controlled to 3 to 4 is added to refractory sand particles of Al2O3, etc. and both are mixed. Next, the blended sand composed of the refractory sand particles deposited and covered with crystalline material of sodium aluminate of molar ratios 3 to 4 is poured into the casting frame of the pattern to mold the casting mold, after which it is set by CO2. This method eliminates the need for any special molding machine and is noise- and vibration- free, thus working environments are improved.
