Definitions
- the present invention relates to a surface pressure load device for a slide valve, and in particular, to equalize the compression of each compression panel, smooth the relative sliding between the surface pressure release plate and the surface pressure release bar, and reduce the weight and durability of parts. New improvement for obtaining improved performance.
- a surface pressure load device for a slide valve of this type for example, a surface pressure load device for a slide gate in Patent Document 1 and a surface pressure load device for a slide valve in Patent Document 2 are known. Can be mentioned.
- a typical slide valve device is provided at the bottom of a molten metal container and has two or three open plate bricks, one of which slides to control the outflow of the molten metal. Pressure is applied to the plate bricks in use in proportion to the depth and density of the molten metal, but the plate bricks are brought into close contact with each other using the repulsive force of the deformed panel to oppose the pressure of the molten metal. Therefore, the required panel power is generally several tons to several tens of tons.
- the spring is deformed by engaging the surface pressure bar with the roller, and pressure is applied to the plate brick.
- the large-diameter roller attached to the surface pressure control bar rides on the angled taper formed on the upper surface of the surface pressure release bar, and pushes down the surface pressure release bar to release the panel. Deform to release the surface pressure.
- the panel is deformed by engaging the surface pressure bar and the roller to apply pressure to the plate brick, and the panel is deformed due to wear and deformation of the surface pressure bar and the roller. Insufficient shape could not be avoided, and if the panel deformation was insufficient, the pressure on the plate brick could overwhelmed the pressure of the molten metal, leading to an accident of molten metal leaking out.
- the large-diameter roller attached to the surface pressure control bar rides on the angled taper formed on the upper surface of the surface pressure release bar, and pushes the surface pressure release bar.
- the surface pressure is released by lowering the panel to lower the surface pressure.
- the angled taper formed on the upper surface of the surface pressure relief bar has an asymmetrical shape, and it is difficult to match the center of the arrangement of the top of the angled shape with the center of the panel with two points.
- Patent Document 1 JP-A-8-117985
- Patent Document 2 Japanese Patent Application Laid-Open No. 2003-200256
- the problem to be solved is that the mountain-shaped tapered portion of the surface pressure release bar is asymmetrical left and right, and the center of arrangement of the two peaks and the center of arrangement of the panel in the horizontal direction are matched. And the bricks cannot be moved smoothly due to lack of panel deformation.
- the engaging point with each projection does not move even when the surface pressure release bar moves, and the uniform force is applied.
- the most important feature is to deform the compression panel.
- the arrangement center of each protruding body formed on the surface pressure release plate and the arrangement center of the panel are completely matched, and the surface pressure release bar is provided. Even if it moves, the point of engagement with each projection does not move, so that the compression panel can be deformed with a uniform force at all times, and the stable surface pressure loading and release of the plate brick can be always performed.
- the sliding of the surface pressure release bar is performed more smoothly.
- the upper roller provided on the lower surface of the housing is in sliding contact with the surface pressure release bar. Therefore, the surface pressure release bar slides smoothly.
- FIG. 1 is a sectional view showing a surface pressure load device for a slide valve according to the present invention. (Example 1)
- FIG. 2 is a side sectional view of FIG.
- FIG. 3 is a sectional view showing another embodiment of FIG. 1. (Example 2)
- FIG. 4 is a side sectional view of FIG. 3.
- FIG. 5 is a cross-sectional view showing another embodiment of FIG. 1. (Example 3)
- FIG. 6 is a side sectional view of FIG. 6.
- the purpose of the surface pressure release bar is to completely align the center of the panel and the center of the projection, and to deform and compress the compression panel with a uniform force to smoothly apply and release the surface pressure. It is realized by the tapered wedge-shaped part and the projection of the surface pressure release plate.
- FIGS. 1 and 2 what is indicated by reference numeral 1 is a nozzle fixed to the lower surface of the bottom of a molten metal container 2 such as a ladle, and clamps 3 are provided on both lower sides of the molten metal container 2 so as to be openable and closable. It is set up. Inside each of the clamps 3, there is provided a slide case 5 housed movably in the up-down direction and connected to the plate driving means 4.
- first and second plate bricks 7 and 8 are incorporated in a two-stage upper and lower manner, and together with an upper nozzle 9, A brick 7 is fixed to the housing 1 side, and the second plate brick 8 is configured to slide by the plate driving means 4.
- An upper nozzle hole 9a formed in the upper nozzle 9 is provided at a lower portion of the slide case 5 through first and second nozzle holes 7a and 8a formed in first and second plate bricks 7 and 8.
- the lower nozzle 10 communicates with the lower nozzle hole 10a.
- a panel holder 12 having a plurality of compression panels 11 as surface pressure load panels is provided on both sides of the housing 1 along a longitudinal direction thereof, and a lower part of the panel holder 12 is integrated with the panel holder 12.
- a surface pressure release plate 13 movably provided up and down is provided.
- a pair of protrusions 14 having at least a semicircular surface are formed on the upper surface of the surface pressure release plate 13 so as to be separated from each other in the longitudinal direction.
- a long surface pressure release bar 15 is slidably inserted and disposed.
- a tapered wedge-shaped portion 16 is formed, and the wedge-shaped portion 16 is configured to be in sliding contact with each of the projections 14 so that the spring holder 12 can move up and down! RU
- each compression panel 11 (that is, corresponds to the position of compression panel 11 located at the center in the longitudinal direction of panel holder 12) ) Coincide with each other, and even if the surface pressure releasing bar 15 slides, the point of engagement with the wedge-shaped portion 16 is at each of the projections 14, so that the position does not move. With the sliding, each compression panel 11 can be compressed with a uniform force.
- surface pressure load hooks 20 for clamping the clamps 3 are rotatably provided via a shaft support 21.
- the surface pressure load hooks 20 are engaged with the clamps 3 when a surface pressure is applied, and the surface pressure load hooks 20 can be removed from the clamps 3 when the surface pressure is released.
- the detachable connecting pin 22 is removed, and the plate driving means 4 is actuated in a state where the surface pressure release bar 15 is not connected to the plate driving means 4, and the second driving is performed.
- the second nozzle hole 8a is shifted with respect to the first nozzle hole 7a, so that the relative positions of the nozzle holes 7a and 8a are changed and the flow rate of the molten steel is controlled.
- the surface pressure release bar 15 is connected to the plate driving means 4 by the connecting pin 22 and slid, and the surface pressure release plate 13 is raised or pushed down by the surface pressure release bar 15 to release the surface pressure or load the surface pressure. It can be performed.
