Cooling water jacket for rapid-cooling quenching furnace and processing method of cooling water jacket

Abstract

The invention relates to the technical field of metal hot processing equipment, in particular to a cooling water jacket for a quick-cooling quenching furnace and a processing method of the cooling water jacket. The cooling water jacket comprises a water jacket assembly, a cooling inner container for storing workpieces and cooling fins annularly arranged on the outer surface of the cooling inner container. According to the cooling water jacket for the quick-cooling quenching furnace, the heat exchange area of the cooling water jacket is increased through the technologies of inserting objects in the jacket and the like, the heat exchange coefficient is increased through cooling fins, the quenching hardness of a workpiece is improved, when the quenching hardness required by the workpiece is low, the water flow is reduced, so that the quenching hardness is reduced, the production cost is also reduced, and the problems that an existing quenching furnace cannot meet the higher required quenching hardness of a workpiece, the hardness of the workpiece is insufficient, an additional electroplating process is needed in the later period, and the production cost is further increased are solved.

Description

technical field [0001] The invention relates to the technical field of metal thermal processing equipment, in particular to a cooling water jacket for a rapid cooling quenching furnace and a processing method thereof. Background technique [0002] Quenching is to heat a metal workpiece to a certain temperature and then suddenly place it in water, oil or cold air to cool it down to increase its hardness. [0003] In order to produce metal workpieces with higher hardness, the metal workpieces are often quenched through a quenching furnace in the later stage of the heat treatment process to improve the hardness and surface effects of the products. In the traditional quenching furnace, a cooling link is added at the outlet of the heating furnace, and the heating furnace is usually connected to a cooling mechanism for rapid cooling. [0004] Water is a traditional refrigerant. As a coolant for quenching process, its thermal conductivity at room temperature is about 0.59W / (m K) t...
