Induction Furnace and Important Operational .

· Electricity is the only energy source for steel melting in the induction furnace. Induction furnace is to run at maximum power since beginning. There are some misconception of running furnace at low tap initially and then gradually increase to higher tap. Maximum power input increases rate of melting and hence reduces cycle time of a heat.
