Application of Induction furnace
Intermediate Frequency Electrical Melting Furnace, also called as Induction Smelting Furnace, which converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting. It is applicable to melting, heating or insulting of steel, copper, iron, aluminum, zinc, tin, nickel silver and other ferrous, nonferrous metal. It can also be used for other heating treatment before forging, sintering and tube-bending forming in the casting and melting industries.

Advantages of induction melting furnace:
1. With strong and durable, beautiful and generous furnace body.Especially for large capacity furnace which need the stronger steel structure .From the point of view of safety dumping has better adopt steel shell furnace.
2. Selenium steel made of magnetic yoke of the magnetic field lines generated by the induction coil has played the role of shielding emission to reduce the magnetic leakage so that it improves the efficiency and energy saving is 5%~8%.
3. The furnace cover reduces heat loss and improves the equipment safety.
Special Features:
Automatic constant temperature function:Values can be preset liquid temperature requirements, one-click startup and attain the goal of automatic constant temperature; Compared with the traditional artificial temperature control, automatic constant temperature function will save time and more sensitive and more accurate, easier to control liquid temperature and oxidation burning loss less, metal components uniform casting product quality is better;
Automatic heating lining function:Heating lining is a relatively complicated and long process of temperature rise curve, to extend the service life of intermediate frequency furnace hearth, reduce production cost, the right build furnace lining technology is very important. The function of automatic lining of innovation, can according to the requirements of the different refractory lining temperature, to preset required by the different stages of heating lining temperature and time; PLC according to the preset time and temperature values, one-click start, automatic matching and stepless regulation of intermediate frequency power, the size of the control of heating speed, prevent lining cracks, and achieve the goal of automatic lining curve. Is to avoid the artificial misoperation and at the same time reduce the labor time and intensity of the workers.
Prevent wear furnace alarm function: prevent alarm system working principle is: wear furnace chamber of a stove or furnace use time to a certain degree, the wall will gradually thinning, the current will vary according to the furnace wall, after the current rate reaches the preset value will make alarm to remind in advance, then automatically cut off the power and predict wear furnace and achieve the goal of safe production in advance.
Safety Protection:
• Main circuit short circuit protection
• Main circuit phase loss protection
• Main circuit phase fault protection
• SCR over-current protection
• SCR overvoltage protection
• Cooling water temperature protection
• Low water pressure protection
• Furnace leakage protection
• Intermediate frequency power failure protection
• Intermediate frequency electric furnace fault protection rate and increase the life obviously

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.
