Calcium Carbide the multi-talent for metallurgy
we can provide our customers the highest service level, a short reaction time and broad reliability - Calcium Carbide
Calcium Carbide - developing new and improving current products

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® 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® 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 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

News

Throughout the whole world, products of AlzChem are established in the steel industry. Starting with the treatment of the molten hot metal exiting the blast furnace along the whole steel production route up to the continuous casting process, AlzChem’s products are well established. As reducing conditions are required in various steps during steelmaking, agents of AlzChem based on Calcium Carbide are adjusted and implemented for decades. As such, we offer a variety of applications and...

Early 2020 AlzChem/Nordic Carbide AB upgraded its’ wagon fleet with a new wagon type for the transport of Calcium Carbide to our customers, who use the Carbide for the production of acetylene. The product is packaged in special containers, so-called Turn Bins, which are then loaded onto rail wagons and transported to our customers. Advantages of the new railroad cars: In addition to the UACNS-wagons for transport of hot metal desulfurization mixtures we have now a second type of wagons...
