Desulphurization at Ladle Furnace for the future EAF route

For the first phase of transition towards green steelmaking, Tata Steel, The Netherlands, has decided to replace one blast furnace with a combination of DRP and EAF. The sulphur content at EAF tap is expected between 200 and 350 ppm, depending on the feed materials.<br/>In the current work, desulphurization trials with the existing ladle furnace were performed by varying the porous plugs life. Desulphurization is better with new porous plugs which brings higher stirring intensity to the steel bath, leading to more slag-steel interaction. Old porous plugs can lead to blockage issues, which reduces the stirring efficiency.
