Abstract
A method of manufacturing granules from slags produced in metallurgical furnaces such as blast furnaces, converter furnaces, electric furnaces and reverberatory furnaces. A molten slag stream from a container at a velocity of at least two meters per second is impinged upon a non-wetting target surface, from which the stream rebounds in a film of projected droplets having the shape of an inverted cone. Cooling and solidifying the droplets by their projected flight in air forms solid granules.
