Abstract
PURPOSE: To obtain a casting having superior impact and abrasion resistances by providing cooling boxed in a mold corresponding to the parts where impact and abrasion resistances are required and cooling molten metal quickly in the process of casting.
CONSTITUTION: Prior to charging of molten metal of high chromium cast iron into a mold 2, the refrigerant flow obtained by entraining a refrigerant in air is fed from a compressor 9 through a refrigerant flow feed pipe 12 into cooling boxed 4, 4', 4", 4'''. When the molten metal of high chromium cast iron is charged through a sprue 6 into the mold 2 after this, the molten metal is cooled quickly by the refrigerant flow and at the gradient in the direction at a right angle thereto via the cooling box surfaces, and the primary crystal austenite and eutectic structure in the resultant casting are fine and crystallize in accordance with the temp. gradient direction, thus the resultant casting has excellent abrasion resistance.
