Working principle: The intermediate frequency melting furnace is mainly composed of a power supply, an furnace body with a induction coil and a crucible. Melting metal will be put in the crucible built with refractory materials. The metal is put in the crucible. After the AC power is turned on, an alternating magnetic field is generated in the induction coil. Being cut by the magnetic line of force , the metal material generates an induced electromotive force, and it creates a induced eddy current to heat and melt metal. During the heating and melting process, the temperature of the induction coil keep same as the surrounding temperature, and there is no harmful gases and bright light to pollute the environment. Melting speed can be controlled by adjusting the frequency and current through the power cabinet.
Application: Intermediate frequency electric furnace is widely apply in melting non-ferrous and ferrous metal. Such as carbon steel, alloy steel, special steel, iron, copper and aluminum, etc.

Aluminum shell furnaces are suitable for small foundry and semi-automatic fundry. Because aluminum shell furnace need amall space. They are easy to operate, they can be manual operation. We can supply you with aluminum shell furnaces from 50-5000kg hourly capacity.
Furnace feature
1. Good start-up performance, no need for professional workers to burn and seal the furnace in advance, and 100% start-up can be achieved for both empty and full furnaces. Fast heating speed, fast smelting speed, high production efficiency,
2. Power saving and low energy consumption, saving power cost. Induction heating is the most energy-saving heating method in electric heating furnaces. Intermediate frequency induction furnaces save 31.5% to 54.3% energy than oil furnace, and save 5% to 40% energy than gas furnace.
3. Less oxidation decarburization and less burning loss, high material utilization rate to save raw material cost. Induction furnace heat so fast, so it cause very little oxidation. The oxidation burning loss of intermediate frequency heating is only 0.5%, and the oxidation burning loss of gas furnace heating is 2%. The coal-fired furnace reaches 3%. In that case, during forging, IF induction furnace can save at least 20-50 kilograms of steel raw materials per ton. compared with the coal-fired furnace.
4. It can reduce the rate of unqualified products by 1.5% and increase the output capacity by 10% to 30%. It has a self-stirring function and make metal temperature and composition to be uniform. The application of a temperature control system can achieve precise temperature control to ensure the quality and capacity.
5. No pollution, improving workers' working environment and company image. During working, there is no harmful gases and bright light created by furnaces, and workers will no longer be roasted and smoked by the coal stove under the scorching sun. It can meet the requirements of environmental protection department
