Abstract

In the steelmaking process, by scrap melting through Electric Arc Furnace route, substantial reduction in electric power consumption and associated increase in furnace productivity can be realized with Scrap Pre-heating Technique which pre-heats the scrap to about 700°C by making use of the sensible heat carried in the furnace off gas. In this respect, CVS Technology has a co-operation with KR Tec GmbH, which developed an ‘’environmentaly friendly’’ and ‘’high efficiency’’ scrap preheating system to be ‘’superior’’ over the existed systems developed so far. This challenge led to the raise of a new and superior ‘’ Environmetal Pre-heating and Continuous Charging (EPC) System’’. The EPC System combines the advantages of 100% scrap preheating and continuous scrap feeding through its chambers, without the need of EAF roof opening. EPC prevents totaly, any dust emission and heat loss during furnace charging stage, as it is the case normally for other operations.
