During cored-wire injection, the content powder is released close to the ladle bottom, far away from oxydation sources (slag, air) and under high ferrostatic pressure. This leads to a better recovery compared to traditional lump or powder additions, especially for elements which are highly oxidizable have a high vapour pressure and / or a low density.

CaSi wire addition to Aluminum- Silicon deoxidized grades permits to achieve very plastic inclusions of the Anorthite type which are favourable to deep drawing (in wire rod for instance) and machinability.

CaSi Wire addition on Silicon- Manganese deoxidized steels with a low Mn/Si ratio can avoid nozzle clogging problems created by high melting point Manganese-Silicates and limit the scum formation which is detrimental to surface quality.
