Description

Technical Field

[0001] The utility model relates to the technical field of metal processing device design, in particular to a surface quenching device for steel processing. Background Art

[0002] Steel parts are materials of certain shapes, sizes and properties made by pressure processing of steel ingots, billets or steel. In order to facilitate subsequent use, the surface of steel parts must be quenched and hardened. Quenching is a surface heat treatment process for steel, which can greatly improve the hardness, wear resistance and fatigue strength of the steel surface, while the interior still has high toughness, which can greatly improve the physical properties of steel. Therefore, steel quenching is an indispensable step in many steel processing processes: At present, most of the steel parts are quenched and hardened manually. First, the steel parts are heated by tools, and then quickly put into the quenching liquid, and then taken out and heated. This operation is repeated to quench the surface of the steel parts. Such operation is more troublesome and the work efficiency is also low. Moreover, since workers need to move constantly, it takes a long time and is more laborious. For this reason, a surface quenching device for steel processing is proposed. Utility Model Content
