摘要

About 35% of the word crude steel production is obtained through EAF route. In the recent times steel-making through Electric Arc Furnaces is gaining popularity due to environmental consideration. Traditionally, only steel scrap was used as input charge material. In the developing economy as in India, availability of scrap is the biggest constraint for EAF steel making. Thus in India appropriate technologies are developed to charge various alternative materials such as pig iron, direct reduced iron(DRI) , hot metal, Iron nuggets etc. Engineering challenges are faced to incorporate such technologies in the existing EAF. This paper deals with some specific examples where appropriate technologies will be utilized to feed various raw materials to reduce cost of steel making and make EAF route competitive.
