How the furnace working ?
The intermediate frequency melting furnace is mainly composed of a power supply, an furnace body with a induction coil and a crucible. Iron and steel will be put in the crucible built with refractory cement. After turned on power, an alternating magnetic field is generated in the induction coil, and then a induced eddy current is created to heat and melt iron and steel .
Furnace features:
1. Electricity fuel, various capacity 0.05T -10T, fast melting speed, 40-60 minutes /pot.
2. Low energy consumption. Induction melting is the most energy-saving melting method among electric melting furnaces.
3. Save raw material. Our furnace cause less burning loss. It can save at least 20-50 kilograms of steel raw materials per ton, compared with the gas, oil or coal-fired furnaces.
4. Reduce unqualified products by 1.5%. The application of a temperature control system can achieve precise temperature control to ensure the quality and capacity.
5. Environmental friendly. 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 environmental requirements of govermment.
6. Easy to maintain,safe and stability.

Why Choose us?
1,Low power consumption
Large current system made of pure copper as conductive medium, the whole circuit with less resistance. Electrode arm shaped as copper-clad box type, resistance and heat can be reduced efficiently. Reasonable arrange of all conductive systems to minimize the resistance of every circuit.
2,Safety & Stability
Full set of hydraulic driving system equipped with accumulator to ensure stability of facilities in the operation process. Whist, equipments can go on the motion when there any emergency accidents happen.
3,High Power Factor
Our power factory could reach over 98%, which could greatly reduce the capacitor box quantities. However we still equip enough capacitor box quantities, which mean your furnace is much much more efficient.
4.High flexibility & Maximum simplicity of operation
HMI used in electrical automation control, interface simulates the real form of furnace, which make the operation more convenient. Mixing feedstock, charging feedstock, melting, tapping all the commands can be implemented by computer.
5.More Durable
We get 6 thyristors on the left, 8 on the right, so even if one thyristor is damaged, our furnace still could be continued use. But many other factories only get only 4 on the right,the whole equipment cannot be used anymore when one thyristor is damaged.
