Abstract

The invention provides a novel jet quenching device with adjustable jet array parameters, and in particular relates to quenching of an ultra-thin steel plate. The novel jet quenching device consists of sliding guide rails, transverse beams, cooling spray pipes and nozzles. The devices are arranged between conveying roller ways, are vertically paired and are perpendicularly and symmetrically distributed relative to a steel plate to be cooled; the distance between the cooling devices and the steel plate is adjustable. When the steel plate is quenched by the novel jet quenching device, the jet array parameters can be flexibly adjusted according to value simulation and test optimization results, jet quenching is performed according to an optimum array layout, and requirements for hardness and flatness specified by technical conditions are further ensured. By virtue of the device, the quenching quality of the ultra-thin steel plate can be obviously improved. The novel jet quenching device is simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a quenching device and method with continuously adjustable jet array parameters, especially for jet quenching of ultra-thin steel plates, and belongs to the field of heat treatment of metal materials. Background technique [0002] At present, the quenching and cooling method commonly used in the industry is to immerse the whole part in the quenching medium, so that the high-temperature parts are rapidly cooled at a rate greater than the critical cooling rate of the steel, and finally martensite is obtained. However, if the overall quenching is used for ultra-thin steel plates, the contact time between each point of the steel plate and the quenching medium will be inconsistent, that is, the cooling rate will be significantly different. Under the joint action of thermal stress and structural stress, severe deformation or even cracking will occur, and the technical conditions cannot be guaranteed. The specified flatness and hardne...
