摘要： The invention relates to a composite wire with a base of cerium and/or rare earths such as mischmetal and intended for insertion into a bath of molten steel so as to de-oxidize and de-sulphurize the steel. When this composite wire is inserted into molten steel, it controls certain inclusions by converting manganese sulphides to sulphides of rare earths, thereby improving the resilience characteristics of the steel. The composite wire is obtained by enclosing the mischmetal wire in a metallic sheath. The diameter of the wire, the thickness of the sheath and the speed of injection are determined in accordance with characteristic curves representing particular proportional relations.
