Acceleration of Melting by Burners in Large Electric Arc Furnace

Abstract

Intensified energy input in the 200-t EAF by means of the twinjet burners has improved the productivity as much as 14%. The combustion in the auxiliary burners is optimum at an efficiency equivalent to the energy more than 80% of electric power. By effective use of an auxiliary combustion energy, high productivity comparable to UHP EAF can be achieved in a large EAF having difficulty to intensify the electric power input.
