Cooling after forging refers to the process of cooling from the final forging temperature to room temperature after finishing forging. If the cooling method of the forged wheel forging is not selected properly, some wheel forgings may sometimes be cracked or even scrapped in actual production. therefore. Pay attention to the choice of cooling method after forging.
For small steel wheel forgings of general steel, they can be directly cooled on the ground after forging. For alloy steel wheel forgings or large wheel forgings, the content of alloy elements and fracture size should be considered to determine the appropriate cooling specifications. Otherwise, various defects are liable to occur. Common defects in the cooling process after forging are: cracks, white spots, reticulated carbides, etc.
