Frequency selection of intermediate frequency furnace

The heating power, heating temperature, heating time and heating frequency of the intermediate frequency furnace are all very important heating parameters. Many people do not pay much attention to the heating frequency of the medium frequency. The consequence is that the heating efficiency is reduced, and even more can not be heated. Why is this? This is because the frequency of the intermediate frequency furnace is not selected correctly.

1. The frequency selection of the intermediate frequency furnace for heating in the forging industry is generally based on the diameter of the heating rod. In principle, the higher the frequency of the intermediate frequency furnace, the lower the penetration depth, and the lower the frequency of the intermediate frequency furnace, the deeper the penetration depth. The frequency of the intermediate frequency furnace becomes smaller as the diameter of the heating rod increases.
2. For the intermediate frequency smelting furnace in the foundry industry, the frequency is mainly related to the stirring of the liquid steel. The lower the frequency of the intermediate frequency furnace, the greater the stirring, and the higher the frequency of the intermediate frequency furnace, the lower the stirring force. When the intermediate frequency smelting furnace is working, the magnetic field of the induction coil of the intermediate frequency furnace and the current flowing through the molten metal together form a stirring force acting on the top surface of the melt. The frequency of the intermediate frequency furnace should be selected according to the actual heating situation, and cannot be generalized.
