The correct quenching operation method of induction heating quenching furnace:

(1) Simultaneous heating and quenching operation When this operation is performed, the operator grasps the workpiece by hand and controls the energization time of the inductor through the foot switch (ie, the heating time of the workpiece). The heating temperature of the workpiece is judged by the fire color: when the workpiece is heated to the specified temperature of the process, immediately turn off the foot switch, and put it in or immerse it in the quenching medium to cool. When heating cylindrical workpieces such as gears and shafts, the hand holding the workpiece still needs to rotate the workpiece.

(2) Simultaneous heating and quenching with a quenching machine tool. When the workpiece is simultaneously heated and quenched on a special quenching machine, the electric parameters of the induction heating quenching furnace and the heating time of the workpiece are adjusted through trial quenching. The entire batch of workpieces can be processed on the quenching machine. Finish. Because under the condition that the electrical parameters of the equipment and the inductor are fixed, the heating temperature of the workpiece is only related to the length of the heating time of the workpiece; once the heating time is fixed, the heating temperature is also determined. These quenching machine tools are equipped with a quenching cooling device, and the quenching machine tool for processing cylindrical workpieces is also provided with a workpiece rotating mechanism. Its processing efficiency and processing quality are high, and it is especially suitable for mass production occasions.

(3) The operation of continuous heating and quenching with induction heating and quenching furnace, when the equipment electrical parameters and the inductor are kept fixed, the heating temperature of the workpiece is only related to the relative moving speed between the workpiece and the inductor. The moving speed is slow, which is equivalent to the long heating time of the workpiece, and the heating temperature is high; on the contrary, the heating temperature is low. After adjusting the electrical parameters and relative moving speed of the equipment through trial quenching, the subsequent operations will be completed by the quenching machine tool.
