Definitions

  • the second technical object of the present invention is to provide a ladle flow control system aiming at overcoming the deficiency of prior art.
  • the extrusion devices for the bottom plate and slide plate are provided, which are featured by reasonable structure, simple operation and high safety and reliability.
  • the third technical object of the present invention is to provide an assembly method for ladle flow control system aiming at overcoming the deficiency of prior art.
  • this method achieves the compression or release of elastic, forms the dynamic process for the building and unloading the slide plate interface pressure.
  • the hold-down force of elastic is generated by sliding the rail wheel on the carrier frame to the rail of housing part. After the generation of pressure, there is no fluctuation in the pressure with the movement of slider, so that the stability of pressure is obviously improved.
  • the fixing mechanism for the bottom plate and slide plate is featured by reasonable structure, convenient and practical operations and high safety and reliability.
  • these rollers may be set as holoaxial rollers or half-axle rollers.
  • an extrusion device is respectively set at one end of notch of slider and at one end of notch of housing.
  • Such extrusion device mainly includes support frame, and the support frame is composed of the upper carrier frame and lower underframe.
  • the upper and lower cover boards are respectively fixed on the surfaces on both sides of carrier frame and fix the centrifugal wheel on the inside of carrier frame through a mandrel.
  • the both ends of underframe are respectively fixed with extrusion poles, and the shapes and positions of the extrusion poles correspond to the edge shapes of the bottom plate and slide plate.
  • the ladle flow control system adopts the relative motion between rails to control the open and close of ladle sliding nozzle in the mode of surface contact and achieves the automatic impaction of device through the rolling mechanism on the carrier frame and the guide rail on the housing.
  • the fluctuation in the slide plate interface pressure is obviously reduced, so that the overall stability of system is improved.
  • this ladle flow control system is featured by reasonable structure, convenient and practical operation and high safety and reliability.
  • Figure 1 is the overall structure scheme of present invention.
  • the present invention provides a ladle flow control system, which includes the base plate 100 fixed on the ladle; A housing 1 is fixed on this base plate 100, the top of housing 1 is connected with the driving mechanism 2 of sliding nozzle; A carrier frame 3 is set on the housing 1, an elastic 4 used for pressure generation is set on the carrier frame 3, a slider 5 is set on the carrier frame 3; The notches 11 and 51(Not shown in the Figure) are set on the corresponding surfaces of the housing 1 and the slider 5, and the bottom plate 111 and slide plate 511 are respectively embedded in the notch 11 and notch 51.
  • Figure 2 is the structure scheme of the housing of present invention.
  • the guide rail 14 forms an inclined plane 141 along the direction of motion of the rolling mechanism 31, and the range of the included angle between this inclined plane and the horizontal plane is 15° - 45°.
  • the specific structure of the blocking part 13 may be designed in multiple forms. As shown in Figure 2 , this structure may be the side wall at one end of the long groove 12 that extends towards the carrier frame 3 along its inner side, and this extended side wall is bending relatively at its top, thus forming the blocking part 13. Or, the structure is the side wall at one end of long groove 12 extends relatively at its top (Not shown in the Figure).
  • the rolling mechanism 31 is composed of rollers symmetrically set on the carrier frame 3. These rollers are holoaxial rollers.
  • Figures 7-9 are the assembly schemes of the ladle flow control system of present invention. As may be known from the Figures, the present invention provides an assembly method for ladle flow control system, which includes the following steps:
  • the elastic 4 that is set on the carrier frame 3 to generate pressure is spring nest 41 in general.
  • a room used to accommodate the spring nest 41 is generally set on the edges on both sides of carrier frame 3. This room may be the groove for the spring nest, and the spring nest 41 is set inside the groove for the spring nest.
  • Figure 10 is the structure scheme for the pressure generation process of the elastic of present invention. As can be known from Figure 10 in combination with Figure 3 , the elastic 4 and rolling mechanism 31 are respectively set on the two sides of carrier frame 3.
  • the holoaxial 311 drives the support pole 411 to make downward motion;
  • the nut 43 drives the cover board 42 to make downward motion, which in turn enables the spring nest 41 to have elastic deformation and generate a pretightening force.
  • This pretightening force is the operating pressure of the flow control system. In such condition, this flow control system may achieve the normal open and close of ladle sliding nozzle under the driving force of the driving mechanism 2 of ladle sliding nozzle.
