  • Method for applying a desired sealing pressure between refractory plates of sliding nozzle
    Patent number: 4233718
    Abstract: A method and apparatus for applying a sealing pressure to the stationary and sliding refractory plates of a sliding nozzle regulating the flow of molten metal from a vessel containing such molten metal. The method includes the steps of positioning the sliding nozzle across the discharge opening of the vessel, applying the desired sealing pressure to the refractory plates mounted between upper and lower metal frames, and then connecting the upper and lower metal frames to secure the refractory plates therebetween and maintain the sealing pressure.

  • Method of regulating the flow of molten metal through the pouring opening of a vessel
    Patent number: 3990614
    Abstract: A method of regulating the flow of molten metal through the pour opening of a vessel is disclosed which is characterized by a combination of a pair of load detecting elements and a contactor which is disposed between the load detecting elements such that there is effected control of a hydraulic cylinder for actuating a sliding control nozzle which is capable of moving bit-by-bit resulting in the fine regulation of the sliding control nozzle.
