  • Strip casting plant
    Patent number: 6585032
    Abstract: A strip casting plant with side limits arranged closely adjacent to a carrying belt. The side limits, and preferably the supply device for molten metal, are capable of vibrating and are connected to a device for producing vibrations. The adhesion of solidified material can thus be prevented.
    Type: Grant
    Filed: November 5, 2001
    Date of Patent: July 1, 2003
    Assignee: Mannesmann AG

  • Process and device for cooling molten steel
    Patent number: 5836377
    Abstract: A process for cooling molten steel, in particular by continuous casting of hoop-steel. At least part of the molten mass that leaves a metallurgical vessel through a metal nozzle solidifies when contacting a cooling surface. A gaseous stream that forms a reducing atmosphere is directed onto the surface of the freely accessible liquid hoop-steel immediately after it leaves the metal nozzle and the surface of the hoop-steel is exposed to this gaseous atmosphere at least until it is completely solidified.

  • Conveyor belt for use in a continuous strip-casting device for the casting of metal strips
    Patent number: 5740852
    Abstract: A conveyor belt of a continuous strip-casting device for casting strips of metal, particularly steel, which belt is guided by a driven drum and a drum horizontally adjacent to the driven drum and displaceable for tensioning the belt. The belt rests in this connection on a support arranged between the drums and the side thereof facing away from the cast strip is cooled. The conveyor belt has, on the side remote from the cast strip, uniformly distributed blind holes. The blind holes are separated by webs of a minimum width. The total surface area of the webs is 0.15 to 0.4 times the total surface area of the belt. The bottoms of the blind holes have a wall thickness which, upon heating by the cast strip with simultaneous cooling of the inside surface of the blind holes, permits a bulging of the bottom of less than 1 mm.
