Mainly used for smelting cast iron, stainless steel, alloy steel, non-ferrous metals, including heavy metals (such as copper, lead) and precious metals (such as gold, silver), etc.
It has the characteristics of high melting efficiency, good electricity saving effect, uniform metal composition, less burning loss, fast temperature rise, easy temperature control and so on. Suitable for all kinds of metal smelting occasions.

If high frequency current flows to be wound into a ring or other shape of heating coil (usually made of copper tube). Therefore, a strong magnetic beam with instantaneous change of polarity is generated in the coil. When the heated objects such as metal are placed in the coil, the magnetic beam will pass through the whole heated object. In the interior of the heated object, the direction opposite to the heating current will generate a corresponding large eddy current. Because there is resistance in the heated object, a lot of Joule heat will be produced, which makes the temperature of the object rise rapidly. To heat all metal materials.
Intermediate frequency power supply is a kind of inverter power supply, which first converts three-phase alternating current rectifier (with thyristor) into single-phase direct current, then inverts the inverter bridge into a pulse alternating current of 500-1000hz, and then through the copper ring in the furnace tank, the steel in the ring generates eddy current and heat, so as to achieve the purpose of steel smelting.
Power factor above 0.98, no need reactive power compensation equipment.
20% energy saving compared to the same capacity general electric furnace.
The two electric furnaces are continuously alternately melted and insulated for simultaneous operation, so that the power supply can always run at full power. This working mode works with two power supplies of one power supply, which greatly reduces the capacity of the transformer.
