Abstract
An additive for a ferrous melt to remove sulphur comprises agglomerates of a mixture of from 15 to 50% by weight of magnesium, 1 to 10% by weight of calcium fluoride and a refractory material to form a metal-permeable matrix when subjected to the temperature of a ferrous melt. The agglomerates may contain a binder and be formed into briquettes. The additive may be introduced into the melt by plunging.
