This paper discusses the effect of the main parameters that affect the desulphurization reaction efficiency. The study was conducted by evaluating different reaction sites within the metal, the slag and the reducing agents. It was possible to establish a mass transfer model that determines the amounts of the reducing agents needed to maintain adequate sulphur levels in the pig iron.

The agent based on magnesium for desulphurisation of iron melts is characterised by the fact the magnesium component is included in an alloy together with other alloy components which reduce the magnesium vapour pressure and/or act as deoxidisers. The magnesium component is separated from the others as an independent alloy, and is introduced into the melt according to the co-injection principle.
