Abstract

The electric steel industry has reached a level of maturity in its relative participation in the world’s steel production. As the industry has grown and matured, EAF steel producers have participated in an ever more competitive market. This competition has led to a continuous search for lower cost alternatives for energy and input materials. Over the years, the Electric Steel Furnace community of operators has developed a variety of technological improvements geared to increasing EAF productivity. Operators have emphasized lowering operating costs and improving the quality of steels produced. Depending on market conditions, the EAF operators may run with different goals and priorities. In times of low demand, the goal may be to operate with an emphasis on cost and the goal of maximizing cost effective use of resources. When the market demand is high the goal may be to maximize EAF throughput. The objective of this work is to list some of the EAF operating best practices observed by our team in the electric arc furnace operations around the world. EAF operators can consider and possibly implement these practices depending on the specifics of each EAF operating reality.
