[0002] At present, industrial furnace workpiece cooling discharging is the indispensable component of heat treatment production line, and the cooling methods of industrial furnace workpiece mainly include in-furnace cooling, air cooling, sand cooling, spray cooling, etc. In-furnace cooling, the workpiece is directly placed in the furnace after forging, and the cooling speed is controlled by adjusting the furnace temperature. It is suitable for the cooling of high-alloy steel, special alloy steel forgings and large forgings after forging. The advantages of in-furnace cooling include uniform cooling and good quality of treated workpieces, and it is suitable for situations with special cooling speed requirements. Air cooling includes cooling in air and stack cooling. The forged piece is directly cooled on the workshop floor after forging, but it should be avoided to be placed on a humid floor or a metal plate, and the draught should be avoided to prevent uneven cooling or local rapid cooling from causing cracks. Air cooling is suitable for the rapid cooling of general steel parts. Sand cooling requires that the sand used for cooling should be dry. The temperature of the workpiece entering the sand should not be lower than 500 DEG C. This method is suitable for the cooling of general steel parts, and the sand can play a role in heat insulation and slow cooling. Spray cooling uses a fan to atomize the water flowing out of the water pipe and blow it onto the forged piece for cooling. This method is suitable for situations that require rapid cooling, and can effectively remove heat through water mist to achieve rapid cooling. Selecting the appropriate cooling method is crucial to ensure the quality of the forged piece, because improper cooling method may cause excessive stress, cracks, network carbide and white spots, and even scrap the forged piece. Therefore, it is very important to select the appropriate cooling method according to the material, size and required cooling speed of the forged piece.
