Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to a rapid quenching and transfer device. Background Art

[0002] Quenching is a metal heat treatment process that heats the metal workpiece to a certain appropriate temperature and maintains it for a period of time, and then immerses it in a quenching medium for rapid cooling. The quenching process includes three stages: heating, heat preservation, and cooling. Heating and heat preservation are generally carried out in a heating furnace, and cooling is carried out in a quenching tank. The quenching tank is generally set below the ground to facilitate the transfer of the workpiece from the heating furnace to the quenching tank; the quenching tank is generally equipped with a lifting mechanism and a material frame. The material frame is used to place the quenched workpiece, and the lifting mechanism is used to drive the material frame to move up and down.

[0003] The existing quenching tank has the following technical problems:

[0004] 1. After the quenched workpiece is hoisted out of the quenching tank by the winch, it needs to be taken out manually, which has low work efficiency and poor safety.

[0005] 2. The transfer time of the heated workpiece from the heating furnace to the quenching tank is long, which affects the quenching quality.

[0006] 3. The high-temperature flue gas generated during the quenching process is released into the environment, affecting environmental protection.

[0007] 4. The waste slag at the bottom of the quenching tank cannot be discharged, and it is necessary to manually remove the slag from the quenching tank regularly. The quenching tank is deep, and the slag removal operation is difficult and cannot be cleaned. Utility Model Content
