Description

    Field of the Invention
  • The present invention relates to a ladle flow control system installed on the outer side of a base plate at the liquid steel outlet of a ladle, which belongs to the technical field of machine manufacturing.
  • Description of the Prior art
  • In the ladle flow control systems of the prior art, the rail wheel is generally set on the slider, and the rail is fixed on the carrier frame. The relative motion between the slider and the carrier frame in this type of flow control system is achieved through rolling of the rail wheel on the rail. Since the pressure transmission in this structure is achieved by means of the rail wheel, its force transmission point is constantly changing, which results in rather obvious fluctuation in pressure. In this way, potential safety hazards may exist, so that the safety factor of the machine is greatly reduced and untimely maintenance may cause accident.
  • Summary of the Invention
  • The technical object of the present invention is to provide a ladle flow control system aiming at overcoming the deficiency of the prior art. In the relative motion between the slider and the carrier frame, the fluctuation of system pressure is obviously reduced, so that the overall stability of the system is improved.
  • Said technical object of the present invention is achieved by means of the technical solution described as follows:
  • A ladle flow control system includes a base plate fixed on the ladle, wherein a housing is fixed on this base plate. The top of the housing is connected with the driving mechanism of the ladle sliding nozzle. A carrier frame is provided on this housing, an elastic used for generating pressure is set on the carrier frame, and a slider is provided on the carrier frame. Notches are set on the corresponding surfaces of housing and slider. The bottom plate and the slide plate are respectively embedded in the notch. A rolling mechanism is provided on said carrier frame, and a guide mechanism is set on the slider correspondingly. The guide mechanism correspondingly set on the slider makes reciprocating motion relative to the rolling mechanism set on the carrier frame, so as to control the opening or closing of the ladle sliding nozzle.
  • The rolling mechanism may be composed of the rollers symmetrically set on the carrier frame, and the guide mechanism may be the guide rail set on the edge of the slider. The orientation pin-jointed part is correspondingly set on the inner side at one end of the carrier frame and on the outer side at one end of the slider, so that the slider may rotate around the carrier frame in a definite mode with the orientation pin-jointed part as its rotating shaft, without the risk of detachment by itself. The orientation pin-jointed part is composed of an arc notch set on the inner side at one end of the carrier frame and a convex pin correspondingly set on the outer side at one end of the slider, or it is composed of a convex pin set on the inner side at one end of the carrier frame and an arc notch correspondingly set on the outer side at one end of the slider, with this convex pin being embedded in the arc notch. This arc notch is in the shape of a sleeve with an opening being set on its side wall. The width of this opening is corresponding to the diameter of the convex pin set on the outer side at the bottom of the slider. At the time of assembly, the convex pin is embedded along the opening of the arc notch. The elastic is a spring box with built-in spring nest. The upper and lower ends of this spring box constitute a carrier frame through two mutually connected beams, and this carrier frame is hinged on the housing.
  • To sum up, in the present invention, the rolling mechanism is symmetrically set on the carrier frame, and the guide mechanism is correspondingly set on the slider. In the relative motion between the slider and the carrier frame, the fluctuation of its pressure is obviously reduced, so that the overall stability of the system is improved.
