Definitions

  • This invention relates to a slide valve for the outlet orifice of a container for molten metal, specifically a steel ladle, having an orifice plate fixedly supported within a slide housing that can be attached to the container, and an apertured slide plate which is movable and fits tightly against the orifice plate.
  • the housing is permanently attached to the jacket of the ladle.
  • the orifice plate which is fixed in the housing with mortar, is also permanently connected with the refractory lining of the ladle by means of the mortar.
  • the housing cover is screwed on tightly so as to press the movable slide plate against the orifice plate in order to assure a tight fit.
  • Irregularities occurring in this manner for example, in the assembly of the orifice plate, have an effect on the sliding surfaces between the orifice plate and the slide plate, upon which the tightness and controllability of the slide valve principally depend.
  • a slide valve having four prefabricated elements which can be assembled and disassembled without mortar, namely, a rigid slide housing, a fixed plate assembly, including a refractory orifice plate mounted in a metal frame which fits and can be inserted into the slide housing, a second, movable, plate assembly, including a refractory slide plate mounted in a metal support with a discharge nozzle below the slide plate, and a metal cover which can be screwed to the slide housing, whereby the contact pressures, on the one hand, between the slide housingand the ladle bottom, and on the other hand, between the two plate assemblies are independent of one another.
  • the slide housing is hinged to the container and can pivot in the manner of a gate that can be locked in closed position and can be attached and removed in the open position.
  • the new construction facilitates replacement of the slide valve within a few minutes, and, moreover, it provides the certainty that the slide plate engages the orifice plate in the desired manner, since preliminary assembly of the slide valve can be carried out without disturbance and with utmost care, away from the operating area of the casting ladle, on a work table.
  • a further advantage of this design, and especially of the pivotable arrangement may be found in the possibility of inspecting the inner parts and mortar joints, and of the ability to come close to the refractory lining of the casting ladle in the area of its discharge, for example, the discharge drain or nozzle, or a gas sink.
  • a slide valve for molten metals specifically steel in contrast to those used in cold assembly, must withstand a very strong radial temperature field pattern which is generated in the refractory portions through which the molten metal flows during operation.
  • the originally precisely ground sealing surfaces of the valve would assume a convex shape during operation and would thereby lose their tightness of engagement.
  • the felt ring can be dimensioned for a joint of known and given width in such a manner that its elastic properties, which are present in spite of the high temperature, serve to absorb safely the expansions occurring during operation.
  • a further instability factor is excluded in that, due to prefabrication of the plate assembly, only geometrically stable, fixed and automatically fitting elements are assembled. If these plate assemblies are prefabricated in a manner whereby the refractory plates are fixed in their supports or frames by mortar, the assemblies are stabilized prior to assembly of the slide plate valve by sufficient drying and setting of the mortar.
  • the construction in accordance with the invention offers the advantage that successive assembly of the individual elements in a slide housing already mounted on the ladle is possible without difficulty. The same also applies for disassembly. This flexibility has many practical advantages, for example, in the event of a quick change of individual parts or for inspection of any wear which might have occurred after the ladle has been emptied.
  • FIG. 1 is a view in vertical cross-section illustrating a representative slide valve according to the invention, illustrating the pivotal mounting of the slide housing;
  • FIG. 2 is a cross-sectional view through the slide valve of FIG. 1, with the sectional plane turned by 90;
  • FIG. 3 is a bottom view of the slide valve shown in FIGS. 1 and 2;
  • FIG. 4 is a side view of the slide housing
  • FIG. 5 is a view showing the slide valve on a casting ladle in pivoted-out position
  • FIG. 6 is a bottom view of the slide valve support frame attached to the bottom of a casting ladle with the slide valve removed;
  • FIG. 7 is an enlarged view in cross-section showing a detail of the sectional view shown in FIG. 1.
  • the slide valve illustrated in the drawings is attached to the metal jacket 1 of a container for molten metal, such as a casting ladle. Only the refractory lining of the casting ladle in the area of the discharge orifice, consisting of a crucible stand 2 and a sleeve 3 are otherwise shown in FIGS. 1 and 2.
  • the slide valve comprises a frame 4 fixed to the casting ladle jacket 1 and a slide housing 5 pivotably hinged on the frame.
  • the swivel axis consists of two joint pins 6 mounted in the same direction on frame 4, which pins engage the perforated side bars 7 of the slide housing 5.
  • the slide housing contains the essential operating elements of the slide valve, namely, a stationary plate 1 1 having an orifice and a movable plate 12 having an aperture which cooperates with the orifice of the plate 1 1 for the purpose of closing the valve.
  • a stationary plate 1 1 having an orifice
  • a movable plate 12 having an aperture which cooperates with the orifice of the plate 1 1 for the purpose of closing the valve.
  • the orifice plate 11 is mortared into a support frame 13 which is centered in the slide housing 5
  • the sliding plate 12 is supported in a cast iron support member 14 having a nozzle or spout 15, which support also accommodates a discharge sleeve 16 below the orifice in the sliding plate 12.
  • the support member 14 rests on the guides 17 of a cover plate 18 which is provided with an opening so that the spout 15 can be displaced longitudinally.
  • the operating rod 19 provided with a hammer head is shown of a hydraulic drive which is used for displacement of the support member 14 and the slide plate 12.
  • the operating rod 19 engages a correspondingly shaped recess 20 (FIG. 5) in the support member 14.
  • the cover plate 18 is locked in place by means of six eye bolts 21 (FIGS. 2 and 3) provided with cup springs 22.
  • two suspension straps 23 are provided by means of which the slide housing can be suspended on a crane, as shown in FIG. 5.
  • FIG. 7 illustrates details of the seal between the elements of the slide plate and the ladle.
  • the plate aggregate consisting of the support frame 13 and the orifice plate 11 mortared into it is inserted into the slide housing 5 after the mortar has dried and set, and it is fastened there by means of several bolts 25.
  • Sealing between the sleeve 3 and the orifice plate 11 is obtained by a refractory felt ring 26, consisting, for example, of Cerafelt or the like, which applies itself around the neck of the orifice plate 1 1 and is, therefore, not exposed to direct attack by the molten metal.
  • a copper-asbestos seal 27 may be provided between the upper plate of the slide housing 5 and the metal jacket of the container 1.
  • a closure for the outlet orifice of a container for molten metal comprising a housing removably attached to a container for molten metal, a joint lying between the housing and the container which contains an elastic refractory sealer, a refractory orifice plate fixed in position within the housing having an orifice for discharge of molten metal, a refractory slide plate movably supported within the housing in sliding engagement with the orifice plate, a metal frame removably mounted in the housing supporting the orifice plate, a metal support for the slide plate, a refractory discharge sleeve below the slide plate, and a metal cover plate removably supported on the housing, wherein the housing is pivotally attached to the container in the manner of a gate and including means for removably retaining the housing at its pivot joint, whereby the contact pressures between the housing and the container and between the orifice plate and the slide plate are independent of each other.
  • Slide closure in accordance with claim 2 including mounting means for removably supporting the housing and the orifice plate therein in fixed and predetermined position with respect to the container.
  • Slide closure in accordance with claim 4 including an upward projection surrounding the orifice in the orifice plate and wherein the refractory felt means surrounds the upward projection.
  • a plate assembly comprising a metal support frame having the refractory orifice plate mortared into the frame so that the support surfaces of the metal frame are parallel to the surface of the orifice plate which-engages the slide plate and are separated therefrom by a predetermined distance.
