Problems solved by technology
[0004] In view of the above-mentioned related technologies, the inventor believes that after the high-temperature workpiece is placed in the quenching pool, the temperature of the quenching medium around the workpiece will rise sharply, and the heat of the quenching medium around the workpiece cannot be dissipated quickly, and the cooling rate is reduced. Austenite is prone to transformation to pearlite structure without martensite, which eventually leads to defects of insufficient quenching hardness in the whole or part of the product after quenching

The invention relates to a quenching device capable of rapidly flowing a quenching medium, and belongs to the technical field of heat treatment equipment.The quenching device comprises a quenching pool, a liquid inlet pipe is arranged on the quenching pool in a communicating mode, an overflow opening is formed in the side wall of the quenching pool, and a quenching launder is arranged in the quenching pool; a plurality of grating plates communicated with the quenching pool are laid at the bottom of the quenching launder, and a longitudinal water pumping mechanism is mounted in the quenching pool and located at the bottom of the quenching launder and used for guiding a quenching medium in the quenching pool into the quenching launder in the vertical direction. The quenching medium in the quenching launder can be selectively promoted to flow in the horizontal or vertical direction according to the workpiece quenching process, so that the heat of the quenching medium around the workpiece can be quickly taken away, and the possibility that the overall or local quenching hardness is insufficient after the workpiece is quenched is reduced.
Description
technical field [0001] The present application relates to the technical field of heat treatment equipment, in particular to a quenching device in which a quenching medium can flow rapidly. Background technique [0002] Heat treatment refers to a metal thermal processing process in which the material is heated, kept warm, and cooled in a solid state to obtain the desired structure and properties. Common heat treatment processes include annealing, quenching, tempering, and normalizing. Specifically, quenching is a heat treatment process in which a metal workpiece is austenitized by heating and then cooled in an appropriate manner to obtain a martensite or bainite structure. [0003] In the related art, when performing quenching heat treatment on a large plate-shaped high-temperature workpiece, a quenching medium is usually placed in a quenching pool, and then the workpiece is placed in the quenching medium for quenching and cooling. [0004] In view of the above-mentioned rel...
