  • Pneumatic flow control of liquid metals
    Patent number: 5381854
    Abstract: A method and apparatus are disclosed for pneumatically controlling the velocity of flow of liquid metal from a tundish into a continuous casting machine through a nozzle. A chamber encloses the nozzle outlet, and at least a portion of the continuous casting machine, and a pressurized gas is supplied to the chamber. The flow velocity of the liquid metal at the nozzle outlet is controlled by controlling the gas pressure in the chamber in response to the level of the liquid metal in the tundish, and the measured atmospheric pressure acting on the liquid metal in the tundish.
