Background
For carbon steel and low alloy steel forgings, the conventional overall heat treatment process includes normalizing, quenching and tempering. Due to the hardenability limitation of the material and the cooling means fixed by heat treatment quenching, theoretically the hardenability limit of the material is difficult to reach in practical operation due to the limitation of environmental factors. In the prior art, the quenching water tank provided with the stirring device is adopted for quenching and cooling, so that the air film attached to the surface of the forged piece can be broken as early as possible, and the water temperature of the whole water tank is uniform by stirring. However, when the forged piece has a complicated geometric structure, particularly when the inner hole is small and blind, and a 90-degree corner exists, the steam pressure of the inner hole is obviously greater than the impact force of water flow obtained by stirring in the cooling process, so that the air film in the inner hole is not broken by the pure external stirring, which is equivalent to the cooling effect that the product is in a solid state, and the cooling speed is seriously slowed down, so that the satisfactory cooling effect cannot be achieved.
