Most of the steel plants were facing the problem of feeding the Sponge-iron continuously as sponge berg formation in the EAF posed lot of problems. The sponge berg, once formed makes the operation very unsteady. It increases the electrode consumption due to the open arcing instead of closed one. It also increases electricity consumption due to the same reason. Refractory consumption too goes up. These are the three major critical parameters in electric steel making.
