Induction heating furnace instruction manual

Induction heating furnace instruction manual

A. Product use

The induction heating furnace is an electric heating device that generates an induction current inside a workpiece in an alternating electromagnetic field based on the principle of electromagnetic induction, thereby heating the workpiece. This device is suitable for heating steel, cast iron and its alloys.

C. Brief description of structure and work process

This equipment is composed of support, translation, lifting device , furnace body and intermediate frequency power cabinet, capacitor cabinet, water-cooled cable, control button box and other devices.

Brief description of the use process :

1. Select the required support bricks according to the heating workpiece ( see Table 1 ) , and place the support bricks and the workpiece on the lifting platform for positioning, and move the workpiece to stop in place.

2. The second step : Select the sensor that is compatible with the workpiece ( see Table 2 ) . The lifting table will work to place the sensor and the heating workpiece in the same center, with equal clearances on all sides.

3. After the lifting system is in place, it will stop automatically and start the intermediate frequency power supply for heating. When the temperature is reached, it will automatically or manually drop and move to complete the heating.

4. Description:

Taking into account the magnetic field radiation, plus the height of the supporting brick and the height of the workpiece, the lifting screw is longer, based on the center of the translation mechanism, and the size of the opening on both sides is 2100mm in length , 50mm in width and 150 in depth . See the figure below for details:
