Alzchem is producing Calcium Carbide for over 100 years. Calcium Carbide is obtained by a reaction of lime and coke in an electric arc furnace at temperatures of around 1,800 to 2,100 °C. Calcium Carbide is of strategic importance to Alzchem as the starting material for the NCN chain (Calcium Carbide/Calcium Cyanamide chain).

Calcium carbide is used as a highly efficient agent in various secondary metallurgy applications.

European steel producers face the need to cover the high quality market with their products. Consumer of steel take following considerations into account: component properties like corosion resistance or fatigue resistance, but also economic issues (e.g. expensive cost driving metals) and machinability. Nitrided steel grades are gaining attention since a reduction of cost driving alloying elements is of increasing importance in the steel industry. In addition, the energy consumption is reduced, as these steel grades enable a less intense heat treatment. Adding Calzot® to the liquid steel before casting leads to a very precise alloying technique. We provide our customers with granulated Calzot® as well as Calzot® Cored Wire. Alzchem stands for solutions, high quality and flexibility so that we generate satisfied customers..

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.

A further step towards digitalization for our customers has been successfully implemented on our homepage.
