The present invention resides essentially in that a proposed mixture comprises an aluminium powder, nitre and a silica-containing component, the mixture composition, according to the invention, incorporating, apart from said constituents, calcium oxide, expanded pearlite or fluorspar, and a silicon-containing component. The proposed mixture provides for the burning thereof with subsequent formation of molten slag therefrom adapted for refining steel in a ladle.

Exothermic slag-forming mixture

A mixture for refining metals, comprising (weight per cent): lime          30 - 70, sodium nitrate     15 - 30, aluminum-containing component 8 - 25, fluorspar       the balance. The proposed mixture is of particular advantage in non-furnace refining of molten ferrous metals of responsible application which should meet most stringent specifications as to their freedom from sulfur, oxygen and non-metalics.
