Comprehensive Analysis for Modernization of 100 t Electric Arc Furnace for Steel Production

Abstract

In this paper is analyzing the current operating conditions of one of electric arc furnace (EAF) in order to evaluate the best option to solve the energy consumption problem. Also we evaluate existing process' equipment performance and point to improvement opportunities. Recommendations for the best operating set-points to run its EAF efficiently are presented. For compensating the reactive energy and increasing the power factor are presented three solutions. By the proposed automation solutions of the auxiliary installations is obtained a substantial reduction of the energy consumption and the defects of mechanical nature. The SVC compensation solution of the reactive energy is the best one, but has also the highest costs.
