Abstract
A reactive cooling medium for apparatus for the manufacture of wire by projecting a jet of liquid steel which contains silicon and manganese through a nozzle into a cooling enclosure containing the reactive cooling medium is characterized by the fact that the reactive cooling medium is a gaseous mixture having an oxidizing power with respect to the steel, at least in the zone adjacent to the orifice of the nozzle, such that the oxidation product of the steel is silica at the thermochemical equilibrium corresponding to the temperature prevailing near the orifice of the nozzle.
