Problems solved by technology
[0002] Metal quenching is a heat treatment process in which steel is heated to a critical temperature and held for a period of time to make it fully or partially austenitized, and then rapidly cooled at a cooling rate greater than the critical cooling rate to transform martensite (or bainite). And nowadays, it is treated by induction quenching, and when cooling in the general metal quenching process, high-temperature steam will be generated at the moment when the high-temperature metal contacts the coolant, and the high-temperature steam generated by the general metal quenching system is not processed. Effective treatment, steam can easily penetrate and corrode the parts of the metal quenching system

The invention discloses a metal quenching system and a quenching process thereof, the metal quenching system comprises an annular induction quenching element, a cooling box, a hydraulic telescopic rod and a metal part lifting block; a surge generating mechanism is arranged between the telescopic end of the hydraulic telescopic rod and the cooling box. When a metal part subjected to electromagnetic induction heating treatment descends and is immersed in quenching cooling liquid to complete quenching cooling, the extrusion column extrudes and slides into the extrusion cylinder in a linkage manner due to descending of the metal part, so that the quenching cooling liquid entering the extrusion cylinder is sprayed out from an inclined nozzle to eject an overturning push plate open, and a surging wave body is formed; and meanwhile, the upper half part of the overturning push plate is positioned above the liquid level of the quenching cooling liquid, so that the overturning push plate which is overturned under the impact of the liquid pushes the quenching cooling liquid towards the direction where the metal piece is positioned to form surge overturning, and steam which is instantly generated after the heated metal piece is in contact with the quenching cooling liquid can be conveniently covered and swallowed.
Description
technical field [0001] The invention relates to the technical field of metal quenching, in particular to a metal quenching system and a quenching process thereof. Background technique [0002] Metal quenching is a heat treatment process in which the steel is heated to a critical temperature, held for a period of time to make it fully or partially austenitized, and then rapidly cooled at a cooling rate greater than the critical cooling rate for martensite (or bainite) transformation. In addition, induction quenching is now used. When cooling is carried out during the general metal quenching process, high-temperature steam will rise at the moment when the high-temperature metal contacts the coolant, and the general metal quenching system does not process the generated high-temperature steam. Effectively treated, steam can easily penetrate and corrode the components of the metal quenching system. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
