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.

Acetylene (C2H2) is the world's most efficient and hottest burning welding gas. For producing acetylene, the reaction of calcium carbide (CaC2) with water (H2O) is used, whereas acetylene and lime milk (Ca(OH)2) is generated.   CaC2 + 2 H2O --> C2H2 + Ca(OH)2   For this simple and proven process, AlzChem's calcium carbide is used for more than a century. Calcium carbide is of strategic value for AlzChem, as it is the basis of the NCN-chain. Originating from calcium...

In the global market the requirements for steel quality are increasing continuously. One of the most important parameters is the cleanliness, which describes the number and size of nonmetallic inclusions in the material. The cored wire CalciPro®, based on Calcium Carbide, is applied in secondary metallurgy to improve the cleanliness. It provides calcium, which modifies the existing oxide and sulfide inclusions in the steel melt and improves castability. The formation, control and effect of...

CaD® is a powerful desulfurization agent based on fine calcium carbide (CaC2) powder. It is available in different grades, which consist of calcium carbide mixed with various supplements. As an example volatile coal powder increases both efficiency and reaction rate. Other additives can optimize slag properties and reduce iron losses. AlzChem produces special CaD® mixtures tailored to the individual requirements of the steel producers.   In the production of high quality steel,...
