Abstract

Process for manufacturing mineral wool from slag, in particular from blast furnaces, characterized in that at least part of the surface of the molten slag is subjected directly to its exit from the blast furnace and without an intermediate reheating stage. Abrupt removal of the particles of material in fusion, being dragged and recovered the threads-filaments and eventually pearls obtained to a shaping chamber.
