Analysis of recyclability of steelmaking secondary metallurgical slag in the electric arc furnace

Abstract

In the steel-making process, the use of slag-forming materials is crucial. However, these materials become wasted after completing their metallurgical task, leading to environmental burdens and costs. Our investigation focuses on the first research phase of finding ways to utilize slags from the secondary treatment of steel production. Our findings reveal that this method could significantly reduce the amount of burnt lime used, thereby reducing greenhouse gas emissions both in the steel plant and the supplier’s end. This result contributes to the green steel production technology development implemented so far at the Max Aicher group of companies, including Ózdi Acélművek Kft.
