Hot Metal Desulfurization

For the hot metal desulfurization in the transfer and the torpedo ladles AlzChem offers highly effective products.

 

Our various CaD mixtures are based on finely ground and homogenized Calcium Carbide. Depending upon customers’ demand, different agents are added such as volatiles or slag modifiers to reduce iron losses.

 

Magnesium is injected together with CaD and/or Lime in the co-injection or multi-injection process in the hot metal ladle desulfurization.

 

Lime, treated by a special fluidization technique, has excellent properties for injection processes for both, hot metal desulfurization and secondary metallurgy applications.
