Abstract (en)
[origin: WO0068439A1] The invention relates to a method for reducing and granulating slag, according to which the molten slag is expelled into a granulating chamber by a propulsion jet. Gases, in particular, air or oxygen are fed into the molten slag to form foamed slag and the temperature of said foamed slag is raised to a temperature ranging between 1420 DEG and 1680 DEG C by the introduction of fuels, such as coal. The foamed slag is then expelled into a granulating chamber. The device has a tundish (1), into which a gas lance (20) opens and/or in whose base nozzles are located (2), in addition to a foamed slag overflow (5) and a slag outlet (6). The tundish (1) is provided with a pressure-tight lid (8), to which a sluice (9) is connected above the slag bath for introducing solid matter and coal. A lance (7) for introducing a carrier gas which expels the foamed slag (4) opens into the slag outlet (6).
