  • Apparatus for producing granules from molten metallurgical slags
    Patent number: 4373883
    Abstract: An apparatus for manufacturing granules from slags produced in metallurgical furnaces such as blast furnaces, converter furnaces, electric furnaces, reverberatory furnaces comprising means for accelerating a stream of molten slag from a container to a velocity of at least two meters per second, and directing the stream onto a target surface from which it rebounds in the form of an inverted cone of droplets which are projected through the air to cool and to solidify them into granules.
    Type: Grant
    Filed: February 18, 1981
    Date of Patent: February 15, 1983

  • Method for producing granules from molten metallurgical slags
    Patent number: 4358415
    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.
