The control of sulphides and oxides and desulphurisation by injection of calcium alloys in liquid steel is used with success in ladle now for many years. In the last years, technique of Ca alloys cored wire was developed as an alternative for inclusions control. A tehcnology using a wire, not welded with a large dia-meter is described so that feeder of the capstan type, making it possible to introduce big quantity of Ca alloys (SiCa-SiCaBa...) or other powdered products. This tech-nique is intended to small foundry ladles or big steel-works ladles as a tool to treat medium tonnages. Treatment in tundish of casters is also possible. Some results achieved in special steels for mechanical industry are given regarding mainly sulphides control by ladle addition.
