INDUCTION FURNACE

An induction furnace is an electrical furnace in which the heat is applied by induction heating of a conductive medium (usually a metal) in a crucible around which water-cooled magnetic coils are wound. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting. Most modern foundries use this type of furnace and now also more iron foundries are replacing cupolas with induction furnaces to melt cast iron, as the former emit lots of dust and other pollutants. Induction furnace capacities range from less than one kilogram to one hundred tonnes capacity, and are used to melt iron and steel, copper, aluminium, and precious metals. The one major drawback to induction furnace usage in a foundry is the lack of refining capacity; charge materials must be clean of oxidation products and of a known composition, and some alloying elements may be lost due to oxidation (and must be re-added to the melt).

Operating frequencies range from mains frequency (50 or 60 Hz) to 10 kHz, usually depending on the material being melted, the capacity of the furnace and the melting speed required - a higher frequency furnace is usually faster to melt a charge. Lower frequencies generate more turbulence in the metal, reducing the power that can be applied to the melt.

An operating induction furnace usually emits a hum or whine (due to magnetostriction), the pitch of which can be used by operators to identify whether the furnace is operating correctly, or at what power level.

GIUL is equipped with two latest Induction Furnace of 15 MT capacity each supplied by Electrotherm India Ltd, the most trusted name in the industry.

Ladle Refining Furnace

Ladle Refining of liquid metal is a proven technology to produce high quality steel. LRF is used to raise the temperature and adjust the chemical composition of molten metal.

Ladle Refining Furnaces (LRFs) are used to desulphurise steel, remove other impurities and hold the molten steel for casting operations. Without LRFs, higher tap temperatures are normally required from steel making furnaces due to heat losses during refining with conventional ladles. Costs of extended furnace time, refractory wear and power/fuel consumption can all be reduced using LRFs to perform holding and refining.

Reduced scrap melting capacity in Basic Oxygen Furnaces (BOF) is another disadvantage of higher tap temperatures. The LRFs also acts as a buffer between the Steel Making Furnace (BOF) or the Electric Arc Furnace (EAF) and the continuous caster, reducing casting costs and allowing greater flexibility in steel making operations.

GIUL is equipped with a LRF of 32 MT capacity, ensuring the optimum quality for the products our valuable customer intend to buy and delivering a supreme cost to value relationship for their money.
