Steel ball quenching device

Abstract

The invention provides a steel ball quenching device. The device comprises a tank containing a cooling medium, a suspension arm extending upwards is arranged on a bracket immersed in the cooling medium, the upper end of the suspension arm is hinged to a support, the bracket is connected with a driving mechanism, the driving mechanism drives the bracket to swing around a hinged shaft core in a reciprocating mode, a steel ball containing container is arranged on the bracket, and the steel ball container is provided with a liquid permeable hole. The driving mechanism drives the bracket to swing in a reciprocating mode around the hinged shaft core, the steel ball containing container arranged on the bracket inevitably and synchronously swings along with the bracket, in the violence process of the bracket, the cooling medium is fully stirred, the temperature of the cooling medium at all positions in the tank tends to be uniform and stable, and the stable and reliable environment temperature is provided for to-be-quenched steel balls.

Description

technical field [0001] The invention relates to heat treatment equipment for steel balls, in particular to quenching equipment for microspheres. Background technique [0002] In the prior art, steel microspheres are widely used as wear-resistant components in the fields of metallurgy, chemical industry, and pharmaceuticals to perform operations such as crushing and grinding on materials. In order to improve the wear resistance of the microspheres, the formed microspheres need to be quenched. Commonly used quenching media include water, oil or air (air cooling). [0003] The scheme of submerged drum is very common. In view of the frequent impact and friction between the wall of the drum and the steel balls, the loss of the drum is very serious. Therefore, it is named "a quenching water tank device for steel ball smelting and industrial processing" ( CN 108642251 A, hereinafter referred to as document 1) is a quenching scheme in which the steel ball receiving basket 3 moves t...

AI Technical Summary

Problems solved by technology

The defect of the two schemes is that the temperature of the medium at both ends of the cooling operation cannot be guaranteed to be consistent, and the temperature conditions required for the quenching treatment of the steel balls cannot be guaranteed to be stable and uniform, which will also seriously affect the quenching quality of the steel balls.

[0006] In addition, steel balls in the form of microspheres are usually formed by coated sand, and then quenched by air cooling is a relatively common solution at present. However, the dust phenomenon during air cooling is extremely prominent, and environmental pollution is a problem that must be solved.
