Slow cooling device for high-temperature knockout of steel castings

Abstract

The invention discloses a slow cooling device for high-temperature knockout of steel castings, and relates to the technical field of slow cooling devices. The problems that an existing slow cooling device still needs to use a crane to unload the steel castings after moving to a corresponding machining site, and workers are easily scalded during loading and unloading are solved. The slow cooling device for high-temperature knockout of the steel castings comprises a supporting plate; and a lifting transmission rod is rotationally connected to the interior of a supporting seat. After the steel casting in the slow cooling device for high-temperature knockout of the steel castings is slowly cooled, the device can be directly pushed to the construction part of the next procedure; the supportingplate at the bottom of the supporting seat can be controlled to move downwards and outwards by rotating a bilateral transmission rod; supporting on the steel casting is relieved; and therefore, the steel casting is stably and safely unloaded out of the device, and the unloading operation can be completed without additionally using equipment such as the crane, so that the operation safety of workers is protected.

Description

technical field [0001] The invention belongs to the technical field of slow cooling devices, and more specifically relates to a slow cooling device for high-temperature boxing of steel castings. Background technique [0002] Slow cooling is to eliminate white spots in steel and avoid cracks caused by thermal stress and structural stress in the recooling process. Some steel materials are put into slow cooling pits for slow cooling, which is called slow cooling. The quality of the slow cooling process has a great relationship with the quality of the steel. All the steel that needs slow cooling is cut and put into the slow cooling pit. The slow cooling time is generally not less than 24h, and the temperature out of the pit is not higher than 150°C. Certain high-speed tool steels, ball steels, alloy tool steels, etc. all require slow cooling. [0003] For example, in the patent with the application number: CN201410516837.1, a high-temperature slow cooling device and casting pro...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a slow cooling device for high-temperature boxing of steel castings, so as to solve the problem that the existing steel castings will be hoisted to the upper part of the slow cooling device for slow cooling after pouring, and will move after the slow cooling is completed. Go to the corresponding location for reprocessing. Although the steel castings have undergone slow cooling when moving, their surface temperature is still high. After moving to the corresponding processing location, it is still necessary to use a crane to unload the material. The steps are cumbersome and increase the overhead of crane equipment. input, and it is easy to burn workers when loading and unloading materials, and the problem of low practicability
