  • Car for transporting a ladle of hot metal and charging the metal to a furnace
    Patent number: 4195822
    Abstract: A car for transporting a ladle of hot metal and charging the metal to a furnace, commonly a BOP or Q-BOP used in steelmaking. The car includes a transversely movable trolley which carries a tiltable support for a ladle. Tilting of the ladle is independent of transverse movement of the trolley. Thus the car can be positioned adjacent the furnace, and the ladle moved tranversely and tilted to dump its contents into the furnace even though the furnace itself is not tilted to a precise position.
