Abstract

799,594. Slag wool. DORTMUND-HORDER HœTTENUNION AKT.-GES. Aug. 2, 1956 [Aug. 13, 1955; Nov. 29, 1955], No. 23896/56. Class 56. In the production of slag wool by blowing blast furnace slag, the slag tapped from the blast furnace is charged into a heatable intermediate vessel and either in that vessel or during its passage from the furnace to the vessel the slag is reduced to an iron content of not more than 0À4 per cent, and up to 5 per cent of silicic acid is added in the intermediate vessel and this is then heated until all the constituents have been completely melted. The reduction may be carried out by, for example, carbon, aluminium or silicon. The slag may then be given an oxidizing treatment to desulphurize it. The reducing and oxidizing treatments may take place at the sane time by lining the hearth with a reducing agent (e.g., a rammed carbonaceous mass) and treating the slag surface with an oxidizing flame.
