[0002] During the production and processing of large forged steel, support rollers are required to support the forged steel. To increase the strength and hardness of the support rollers, the support rollers need to be quenched during the production process. In the prior art, the utility model patent application number 201520302091.4 discloses a device for induction hardening the surface of a circular workpiece. The device mainly consists of a rotating worktable, a fixture, a high-frequency hardening sensor, and a water tank. During use, the workpiece is clamped and fixed by the fixture. The workpiece is then heated to a certain temperature by the quenching sensor. After that, coolant is sprayed onto the surface of the workpiece to quickly cool it. The coolant then falls into the water tank. The inventor believes that there is a problem during use. After the coolant is sprayed on the workpiece, it falls directly into the water tank.
