Hot Metal Desulphurisation (KR)

In the case of the Kanbara refining (KR) process, hot metal desulphurisation is carried out by stirring bulk materials into the bath with a refractory coated immersing impeller. The unit may consist of one or two treatment chambers with movable covers and is connected to a dedusting system. A slag skimming device can be integrated or provided in a separate position. Further equipment usually include a temperature measuring and sampling system.

The Kanbara refining process is often considered where there is a supply of very low cost desulphurisation reagent.
