ABSTRACT:
Treatment agents for steel suitable for desulphurizing molten steel comprise granules containing both magnesium oxide and/or carbonate and aluminium, the proportion of aluminium in the surface of the granules being substantially less than the overall proportion of aluminium in the granules. The granules are suitable for application into the molten steel via injection techniques.
