SUMMARY:Key parameters for a successful and efficient process transformation from converter-steelmaking to steelmaking with electric arc furnace
DESCRIPTION:A comprehensive process transformation from a conventional integrated steel plant with blast furnace and converter into a modern electric steel plant with the aim of drastically reducing CO2 emissions is technically not easy and requires a careful consideration of all possible solutions. In particular, the effects on both - productivity and the quality of steel grades to be produced should not be underestimated or neglected.

This article describes one of several possible solutions for the transformation of integrated steel plants:
The implementation of an electric arc furnace - possibly together with a new reduction reactor to use direct reduced iron. 

Various considerations and challenges are identified in this paper, such as:
Maintaining the original tapping weight or working with a different tap weight (partial tapping), is the necessary electrical connection capacity available or the given network stability sufficient and what solutions are available if not, is enough space available in a steel plant that has grown over decades for an integration of a new melting unit with reduction reactor, how will the raw material situation look like in 10 or 20 years?

What is possible with an electric arc furnace? Is it realistic to produce actual steel grade qualities using an EAF as melting unit - and if yes - with how much virgin material? Does the possible or needed raw material scenario change the overall productivity? Can existing equipment in secondary metallurgy be reused or is there additional investment needed as well? 

All these questions and challenges will be explained and described in this article based on existing reference examples in cooperation with Stahl-Holding Saar for the locations in Dillingen and Völklingen.
