Medium frequency furnace

The medium frequency melting furnace is a power supply device that converts the industrial frequency 50HZ AC into medium frequency (300HZ or more to 20KHZ). This conversion makes the current more suitable for the needs of metal smelting, improving the smelting efficiency and energy utilization. It is used in the smelting of non-ferrous metals and ferrous metals, such as steel, alloy steel, special steel, etc. Its melting capacity and stable performance make it an indispensable and important equipment in modern smelting technology.

Using the principle of electromagnetic induction heating, the heat is generated by the workpiece itself, the heating speed is fast, oxidation is very small, the process repeatability is good, materials and costs are saved, and the mold life is extended.

The high degree of automation can realize fully automatic unmanned operation, reduce the labor intensity of workers and improve production efficiency.

Induction heating generates heat inside the workpiece, heating is uniform, and the temperature difference between the core and the surface is extremely small. The application of temperature control system can achieve precise control of temperature, ensure product repetitive accuracy, and improve product quality and qualification rate.

The furnace body and lining are made of new structure and new materials, which shortens the smelting time and reduces heat loss.

It heats the metal by electromagnetic induction, and the temperature rises and melts quickly. It is suitable for intermittent operations and frequent changes in metal grades, and has strong adaptability.

The heating efficiency is high, compared with coal stoves, the energy consumption is low, the labor productivity is high, and there is no pollution.

Suitable for smelting various metals, such as platinum, gold, K gold, silver, copper, aluminum, etc.
