Abstract

The invention discloses a subsurface injection quenching cooling device which comprises a quenching tank, an internal pipeline, a jet pump, nozzles and an external pipeline. The subsurface injection quenching cooling device disclosed by the invention has the following beneficial effects: after quenching liquid is sprayed out of multiple nozzles from bottom to top, the liquid pressure in a pipe isgradually reduced. Meanwhile, the liquid pressure in the quenching tank outside the pipe is also reduced from bottom to top, thus a uniform and consistent pressure difference can be obtained, consistent spraying speed of the quenching liquid from the nozzles is ensured, and a flow field that is uniform and consistent up and down is obtained. A proper distance is maintained between the nozzles anda workpiece, and the quenching liquid sprayed out of the nozzles can drive the quenching liquid around to flow sufficiently, so as to improve the quenching effect.

Description

technical field [0001] The invention belongs to the technical field of heat treatment equipment, in particular to a submerged spray quenching cooling device capable of rapidly cooling workpieces. Background technique [0002] Quenching process is a widely used heat treatment process, which is to quickly put the workpiece into the cooling liquid at high temperature for rapid cooling. The cooling intensity and cooling uniformity of the cooling process are the key to the process. [0003] At present, most quenching heat treatment equipment uses propeller propulsion stirring, bottom spring stirring or jet stirring to cool the workpiece, but these stirring methods make the coolant flow along the surface of the workpiece in a fixed direction, so the cooling of the workpiece The ability is relatively weak, and the cooling is uneven at the same time, which can easily lead to defects such as deformation and large process dispersion. Especially in the water medium quenching process,...
