How does the quenching of the guide wheel induction heating furnace work?
The difference between the guide wheel and drive wheel quenching machine is that the former is a scanning quenching, while the latter is a one-time heating and quenching. Figure 8-32 shows the main part of the quenching of the guide wheel induction heating furnace. The quenching of the guide wheel induction heating furnace is generally applicable to the quenching of the driving wheel induction heating furnace, but a set of rotation device is installed on the workpiece positioning shaft, which can make the positioning shaft perform stepless speed change. When the guide wheel is quenched and heated, the left and right wheel faces and shoulders are carried out at the same time, and there is a liquid sprayer under the effective circle of the sensor. When the guide wheel is scanned and quenched to the end, there must be a transition zone for repeated heating. In order to reduce the length of the transition zone, the width of the effective part of the sensor cannot be designed too wide; in order to prevent the transition zone from being generated on a straight section, when the effective circle of the sensor is arranged on two rims, it should be separated from the front and back. distance.
