The principle of induction melting is that a high voltage electrical source from a primary coil induces a low voltage, high current in the metal or secondary coil. Induction heating is simply a method of transferring heat energy.

Induction furnaces are ideal for melting and alloying a wide variety of metals with minimum melt losses, however, little refining of the metal is possible until sequenced with “ladle refining furnace”. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting.

There are fewer chemical reactions to manage in induction furnaces, making it easier to achieve melt composition. However, its sensitivity to quality of charge materials when compared to other melting processes restricts the types of scrap that can be melted. The inherent induction stirring provides excellent metal homogeneity.

The liquid steel is then poured from the electric furnace into a ladle, while at the same time eliminating impurities and making a first time adjustment to the chemical composition by way of adding alloys containing the necessary elements for the optimum quality of the steel.

Mughal Iron and Steel Industries Limited (MISIL) imports high quality scrap, Direct-Reduced Iron [DRI], Shredded and HMS low-carbon scrap in accordance with ISRI standards, which in turn is sorted and separated. Electric Induction Furnaces (EIFs), ideal for melting and alloying a wide variety of metals from world’s most known manufacturers Electrother, Megatherm, are used to produce molten metal at 1600 -1700 °C. This infrastructure has optimized the production capacity of MISIL for making steel, around 200,000 tons of Mild Steel and Carbon Steel Billets annually.
