Milled Quicklime

In the hot metal desulphurization process, Carmeuse offers fluid milled lime or blends to be injected into the hot metal through an immersed lance using an inert carrier gas such as argon or nitrogen. Since desulphurization is a diffusion-controlled reaction and related to the reactive surface area available for reaction, the lime must be as fine as possible and very flowable.

Key Considerations

Sinter Plant:

  • Sinter-mix basicity
  • Agglomeration efficiency and water demand
  • Fuel consumption
  • Sinter return


Hot Metal Desulphurization:

  • Injection or co-injection with magnesium
  • Initial and targeted sulphur level
