Description

Technical Field

[0001] This utility model relates to the field of heat treatment of metallic materials, specifically a semi-immersion water quenching device with an irregularly shaped tank. Background Technology

[0002] Quenching of steel pipes is a common process that involves heating the steel pipe to a certain temperature, rapidly cooling it, and then tempering it to significantly improve its overall performance. Currently, there are three main quenching cooling methods in industrial production: single external surface spray cooling, external spraying followed by internal spraying, and immersion cooling. Existing semi-immersion water-quenching steel pipe quenching steps include a feeding device, a receiving device, a first-stage retaining device, a second-stage retaining device, and rotating rollers in the semi-immersion tank. After quenching, the pipe is removed, completing the entire operation. However, the operation of these devices causes surface scratches and dents, compromising the appearance quality of the steel pipes. In the production of thin-walled steel pipes, this can lead to scrap and affect product quality. Therefore, it is necessary to design a semi-immersion water quenching device with a special-shaped tank that provides good quenching results and reduces damage during the quenching process.

The inner wall of the top of each of the several chains is sleeved with the shaft end surface of several sets of roller components. Each of the several roller components is installed and connected to the inner wall of the irregular semi-immersion water quenching tank through a mounting seat.

[0006] The bottom of the inner wall of the irregular semi-immersion water quenching tank is designed with a double layer, and both layers are designed with slag flushing slopes.

[0007] Furthermore, the material feeding assembly includes a feeding motor installed at the connection position between the support frame and the irregular semi-immersion water quenching tank. The output shaft of the feeding motor is fixedly connected to a rotating shaft, and the surface of the rotating shaft is provided with several feeding rods.

[0008] Moreover, the feeding assembly is arranged between several support rollers and auxiliary roller components, and the feeding assembly can be used to stably place the quenched steel pipe between the support rollers and auxiliary roller components.

[0009] Moreover, one end of the feeding assembly structure is disposed between several support rollers and on its side, and the other end is disposed between several pairs of rollers.
