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.

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,...

AlzChem is the only REACH registered producer of calcium cyanamide. Starting from June 2018 only AlzChem is allowed to distribute Calzot® (CaCN2) in Europe. Calzot® is based on the chemical compound calcium cyanamide (CaCN2) and is applied in metallurgical processes. The main use of Calzot® is for nitriding liquid steel by addition of Calzot® in lumpy form or as a cored wire. The nitrogen dissolves in the melt and contributes to an increase in both strength and corrosion resistance of the...

AlzChem introduced CalciPro®, a cored wire based on Calcium Carbide, in the market, which is used for Calcium treatment in secondary metallurgy. It converts alumina inclusions into calcium aluminates to prevent clogging with high efficiency and hence reliably improves castability. Moreover, it is an excellent solution to modify inclusions in order to enhance steel properties such as machinability. The cored wire is packed in a container which guarantees highest safety in transport, storage...
