Abstract
Method of making wire-like treatment agent for metal melts e.g. ferrous ones comprises heating metal tube (1) e.g. of steel, introducing into the tube (1) a melt (3) having a temperature below melting point of the metal of the tube and comprising a reactive metal e.g. magnesium and cooling the tube (1) and the melt inside it to solidify the melt in the tube (1). Wire-like treatment agent itself comprises solidified melt (11) comprising a reactive metal encased in a preformed tube (1) of metal of higher melting point than that of the reactive metal.
