Desulphurization of Hot Metal – IspatGuru

Important issues in desulphurization of hot metal . During the desulphurizing process, the generation of slag is proportional to the amount of reagent added to the hot metal. Also during the process, some hot metal gets trapped in the slag and gets pulled out of transfer ladle during the slag rimming.KR Hot Metal Desulfurization System | Steel Plantech,KR Hot Metal Desulfurization System.
