What is quenching in a buried liquid induction heating furnace?

The quenching of the buried liquid induction heating furnace is a machine tool that is heated and quenched under the oil layer. The quenched part of the workpiece and the inductor are both immersed in oil. The purpose is to heat the workpiece in oil and use the surrounding oil as the quenching cooling medium. When the heating is over, the surrounding oil is used to cool the heating layer. Because the quenching intensity of this quenching cooling medium is weak, it is suitable for processing workpieces that reduce distortion and prevent cracking. To this end, the process must meet two conditions: the heating power density must be large enough so that the surface of the workpiece can be quickly heated to the required quenching temperature under the condition of a static liquid; the quenching intensity of this liquid should be low, and the rapid heating of the workpiece should not be blocked . Figure 8-33 shows the machine tool for shaft scanning and quenching under the oil layer.
