Cooling and slag removing device for salt bath tank

Abstract

The invention discloses a salt bath cooling and slag removing device which comprises a cooling water inlet end, a cooling water outlet end and a cooling water pipe, the cooling water inlet end and the cooling water outlet end are communicated through the cooling water pipe, and the cooling water pipe is immersed in salt liquid of a salt bath. The cooling problem of the salt bath tank is solved, and meanwhile, salt slag in the salt bath tank is convenient to clean, so that quenching salt in the salt bath tank keeps certain cleanliness and quenching intensity consistency, and the salt bath tank is reliable in performance, can be adaptive to various types of quenching salt bath tanks, is flexible in application and has a wide market space.

Description

technical field [0001] The invention relates to the technical field of quenching salt baths, in particular to a cooling slag cleaning device for a salt bath bath. Background technique [0002] At present, slag removal in the quenching salt tank generally adopts the form of filtration, and the effect is very unsatisfactory, resulting in a large amount of salt slag in the quenching tank, which leads to a significant decrease in the cooling performance of the quenching salt, and finally leads to uneven hardness of the quenched workpiece after quenching, and the workpiece is quenched. The core cannot be hardened. However, the cooling of the existing quenching tank adopts air-cooling cooling. Due to the low heat transfer coefficient of the air, the cooling effect is not good, and the quenching structure is finally affected. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a salt bath cooling slag cleaning device to solve the above-mentioned ...

Problems solved by technology

[0002] At present, the slag removal in the quenching salt tank generally adopts the form of filtration, and the effect is very unsatisfactory, resulting in a large amount of salt slag in the quenching tank, which leads to a significant decline in the cooling performance of the quenching salt, and finally leads to uneven hardness of the quenched workpiece after quenching, and the workpiece The heart cannot be hardened

However, the existing quenching tanks are cooled by air cooling. Due to the low heat transfer coefficient of air, the cooling effect is not good, and the quenching structure is finally affected.
