Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of forgings, in particular to an automatic cooling device for quenching annular forgings. Background Art

[0002] Some ring forgings need to be quenched. During the quenching process, the ring forgings are first heated to make them fully or partially austenitized, and then quickly cooled to below a certain temperature for martensitic transformation, which can improve the hardness, wear resistance and toughness of the ring forgings.

[0003] However, the existing automatic cooling device for quenching annular forgings still has the following shortcomings: the existing automatic cooling device for quenching annular forgings has a relatively simple structure, and when in use, the annular forgings are directly placed in cooling water for cooling, resulting in the accumulation of the annular forgings in the cooling water, affecting the cooling effect and causing uneven cooling. Therefore, we propose an automatic cooling device for quenching annular forgings. Utility Model Content
