Secondary Metallurgy

Calcium Carbide is applied in various processes in the secondary metallurgy of steel. As a fine powder it is injected  in the deep desulfurization. Fine grained or lumpy product is applied for deoxidation at tapping and for slag reduction.

Calzot® offers an effective, safe and low cost method to the steel worker for nitrification in liquid metal processing as well as in nitride hardening of finished components.

CalciPro® expands the well-established cored wire technology with the filling material Calcium Carbide. The application of CalciPro® in the calcium treatment of steel leads to highest efficiency, safety and lowest costs.

CalciPro®

CalciPro® improves castability by preventing clogging during continuous casting. It is used to modify inclusions and to improve steel properties like machinability.

AlzChem offers a solution for safe transport, storage and handling. The conventional 13 mm cored wire is directly pulled out of an approved container.

 

Performance benefits:

  • Reduction of Ca-treatment costs per ton steel
  • Reduction of treatment time
  • High Calcium yield
  • Improved castability
  • Improved steel quality and effective inclusion modification
  • Low environmental impact
  • Universal application - especially for low-Si grades

 

Calzot®

Calzot® is an effective, safe and low cost additive for nitrogen alloying in liquid metal processing as well as in nitride hardening of finished components.

Calzot® is offered in paper or plastic bags, steel drums, bigbags or as cored wire.
Depending on application purpose and technique we will recommend the suitable granulation.
The highest yield and precision is reached when Calzot® is applied as cored wire.

 

Performance benefits:

  • Significant cost savings compared to Ferro alloys
  • High and constant nitrogen content for safe alloying
  • Less temperature and less time compared to alloying via gas phase
  • Lowest level of impurities

 

 

 

 

Calcium Carbide

Calcium Carbide is a highly powerful reagent for various applications in secondary metallurgy:

  • Desulfurization to ultra-low sulfur contents by injection of fine Calcium Carbide powder
  • Deoxidation and slag treatment by addition of coarse Calcium Carbide during tapping or at the ladle treatment station

Calcium Carbide is packed in containers from 1 to 1.5 t or in steel drums of 120 kg.
Different granulations are available.

 

Performance benefits:

  • Reduced costs and improved cleanliness due to gaseous deoxidation products
  • Ultra-low sulfur contents and slag with high sulfur capacity
  • Recovery of oxidized metals like Cr, Mn, Si, Fe
  • Fast reduction of aggressive furnace slag results in increased refractory life
  • Less consumption of synthetic slag and slag builders

Clean steel with CalciPro®

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® - Hot metal desulfurization

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,...

Calzot® - AlzChem is single REACH registrant

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...

CalciPro® - Cored wire based on Calcium Carbide

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...
