What is the difference between an intermediate frequency furnace and a high frequency furnace

1. The frequency of the alternating current used is different: the intermediate frequency furnace is a power supply device that converts the power frequency 50HZ alternating current into the intermediate frequency (above 300HZ to 10000HZ); the high frequency furnace usually has a current frequency of one hundred to five hundred kilohertz under clear conditions. between;

2, the higher the frequency, the lower the heat transmission capacity;

3. The effective hardening depth of the intermediate frequency furnace is 2 to 10 mm, and the main application range is parts that require a deeper hardening layer; the effective hardening depth of the high-frequency furnace is between 0.5 and 2 mm.

4. The intermediate frequency furnace can be used to smelt various metals ranging from five kilograms to sixty tons; high-frequency induction heating is suitable for smelting one to five kilograms of precious metals.

5. The intermediate frequency furnace is large in size and the technology is mature; the high frequency furnace is small in size, fast in operation and low in price.

Although both intermediate frequency furnace and high frequency furnace are commonly used smelting equipment, the difference between the two is obvious, such as price, volume, smelting efficiency, etc., are very different.
