Problems solved by technology
In addition to being greatly affected by the quenching medium, the cooling rate of the quenched workpiece is mainly affected by the flow rate of the quenching liquid itself. However, it is not easy to control the flow rate of the quenching liquid around the quenched workpiece, which affects the cooling rate of the quenched workpiece. , Moreover, this quenching and cooling method will make the quenched workpiece cool unevenly and affect the performance of the quenched workpiece

The invention discloses a quenching cooling system and a quenching cooling method in the technical field of heat treatment. Two groups of upright posts which are arranged in parallel are symmetricallyand vertically arranged at the left end and the right end of the top of a mounting base; the top of a transverse rod is connected with a telescopic cylinder through a fixed base; a quenching agent box is arranged at a power output end of the right side of the telescopic cylinder; an air jet head is mounted on the side wall of an inner cavity of a quenching tank; a cloth belt filtering device is transversely mounted in the inner cavity of the quenching tank; the bottom of the right side of the quenching tank is also connected with a circulating pump through a pipeline; and the right side of the circulating pump is connected with the side wall of the quenching agent box through a hose. According to the quenching cooling system and the quenching cooling method, turbulent flow is formed by aquenching agent by utilizing an air jet device; the flow speed of a quenching medium is accelerated; meanwhile, the quenching medium is sprayed on the surface of a workpiece so as to accelerate the heat exchange speed of the workpiece and the quenching medium; the overall quenching speed of the workpiece is improved; a quenched layer formed on the surface of the workpiece is uniform in thickness;and the machining quality of the workpiece is improved.
Description
technical field [0001] The invention relates to the technical field of heat treatment, in particular to a quenching cooling system and a quenching cooling method. Background technique [0002] Quenching is a method of rapidly cooling steel or alloys that have been heated at high temperature and held for an appropriate time to improve the hardness, strength and wear resistance of the steel. The existing quenching and cooling process generally uses cranes and other hoisting equipment to lift the steel from the heating furnace and immerse it in the quenching liquid for quenching and cooling. Since the quenched workpiece is always in one position, the cooling process mainly depends on the quenching liquid. Its own flow exchanges heat with the quenched workpiece. The cooling rate of the quenched workpiece is not only greatly affected by the quenching medium, but also mainly affected by the flow rate of the quenching liquid itself. However, it is not easy to control the flow rate...
