hot metal desulphurization plant:

Hot metal treatment SMS group

Commonly used injection agents such as calcium carbide or magnesium are often in short supply and therefore expensive. For this reason, SMS group offers an alternative technology in which inexpensive agents can be used for hot metal desulphurization: Instead of injection via immersion lances, a rotating stirrer mixes the liquid pig iron with the desulfurization agent.

Hot Metal Desulphurization Carmeuse

In the hot metal desulphurization process, efficiency and metallic yield both partly depend on the quality and reliability of desulphurization’s fluxes and flowability. Carmeuse provides fluidised milled lime in its purest and finest form to the specifications or blended with slag liquefiers and magnesium metal.
