Hot metal desulphurisation plants from Polysius are in operation all around the world. More than 50 plants are desulphurising hot metal in torpedo and transfer ladles with capacities of 35 to 350 tonnes.

Polysius injection systems can be used for all commercially standard desulphurisation reagents, such as lime, calcium carbide and magnesium, using the mono-, co- or multi-injection processes.

The MEPOL control system, specially developed by Polysius for injection systems, assures a very high desulphurisation reagent dosing precision and minimises the operating expense of the hot metal desulphurisation process with the aid of a metallurgical process computer.
