[0003] The traditional quenching device for the production of steel round tubes has the following shortcomings: the traditional quenching device for the production of steel round tubes generally uses high-frequency induction quenching equipment for quenching; this equipment uses high-frequency current to generate eddy currents inside the workpiece, thereby rapidly heating the surface or local part of the workpiece and then rapidly cooling it to achieve a quenching effect. When quenching, the device needs to slowly pass the round tube through the current to perform surface quenching, but due to the different contact intervals between the round tube and the current, the heating effects on both sides of the outer wall of the round tube may be different during heating, thereby affecting the overall heating effect. Therefore, it needs to be improved. Utility Model Content
