| Aluminium | Aluminium granules are particularly suitable for the de-oxidation of steel during tapping of liquid steel from the EAF and BOF, for slag killing, as well as for chemical heating of the molten steel in the CAS-OB process. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
|
| Calcium | Calcium powder and granules for the production of injection mixtures and and cored wires for the Ca- treatment of steel grades with very low Silicon content. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
|
| Calcium multi component alloys | SKW Metallurgie has special know-how to melt complex multi component Calcium alloys and to provide these according to customers’ requests. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
|
| Calcium-Aluminium | Calcium-Aluminium is used for deoxidation alloyed and non-alloyed steels, in which the silicon content is limited. It has been particularly successful when used in deep drawing and heat-resistant steels. Of technical importance is also the deoxidation of the slags during the ESR process. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |

| CaSi | CaSi is a universal desoxidising and desulphurising agent used for the manufacture of killed plain Carbon and high grade steels. It is used either as a substitute for Aluminium or as a supplement when the use of Aluminium poses analytical problems ( e.g. coarse grain steels). In combination with Aluminium, it is used in cases where very high demands are made on the degree of purity and the surface quality of the steel. By injection of powdered CaSi into the ladle a high degree of cleanliness can be attained, which was previously only possible with special metallurgical processes. | Sabine Disterer Tel: +49 (0)86 34 / 62720-42 Fax: +49 (0)86 34 / 62720-45 disterer@skw-steel.com |
|
| Carbide mix | Calcium Carbide is used in the steel industry in large quantities for the desulphurisation of hot metal. There is however also a range of applications within the secondary steel metallurgy, e.g. deoxidation at converter tapping, slag killing, foam slag in the ladle furnace, steel desulphurisation and inclusion modification. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
|
| MnCaSi | MnCaSi is a deoxidation and modification alloy which is ideal for application in all currently used processes for the production of non-alloyed, low-alloy and high-alloy steels. In many cases, MnCaSi is also used as a slag reducing agent in high-alloy steels. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
|
| Nitrifer | Nitrifer is used in steel metallurgy as a cost-efficient agent for nitrification. Here different addition techniques are practiced: Addition of bags or tin cans into the ladle during tappingInjection of Nitrifer by pneumatic lance injection or by cored wire. | Sandra Dietel Tel: +49 (0)86 34 / 62720-49 Fax: +49 (0)86 34 / 62720-45 dietel@skw-steel.com |
