This article discusses how the Goodfellow EFSOP technology was used to achieve a reduction in electrical energy and power-on time at TAMSA. Other benefits include a reduction in charged coke usage and electrode consumption, as well as an increase in productivity.

The international steel community is faced with the challenge to develop processes that will make steel production more sustainable in the future. Specifically, processes that produce less CO2 and fewer net waste materials and emissions, and consume less energy are required. This article outlines where energy consumption and CO2 emissions are high and can be reduced. Reductions can be achieved by incremental improvements to existing processes or by breakthrough, innovative processes; both strategies are examined. Since most of the energy consumption and CO2 generation occurs in ironmaking, research in this area is emphasized. Research on controlling the cohesive zone in the blast furnace, improving the final stages of reduction in direct reduction processes, the use of biomass and other innovative processes for ironmaking are reviewed. In oxygen steelmaking, improved postcombustion to allow for more scrap melting is examined. Postcombustion and slag foaming in the EAF in order to reduce energy are reviewed.
