I ERA/s7" MEIER BY his Arromvzrs SLIDE CLOSURE FOR RECEPTACLE FOR MOLTEN METALS BACKGROUND OF THE INVENTION 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.
In slide valves proposed heretofore, the housing is permanently attached to the jacket of the ladle. As a result, 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. In addition, 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. The disadvantages of this design become apparent from the frequent necessity for a change of worn parts of the slide valve, specifically the orifice plate and the slide plate. In order to change the parts, the casing cover and the slide plate are first removed and then the orifice plate must be broken away from the hot ladle by assiduous work. This is followed by affixing a new orifice plate on the ladle, treatment and cleaning of the slide surfaces by means of graphite or molykote, the mounting of a new slide plate, the assembly of the casing cover, coupling of the drive for the slide and the tightening of the check screws. During this operation, which usually takes more than an hour, the casting ladle is idle. To all this must be added another, very important disadvantage, namely, that the cover of the casing which presses the slide plate against the orifice plate, must not be tightened until the mortar with which the new orifice plate is mounted has become completely dry so that the contact pressure of the cover encounters a safe support. Apart from the fact that the setting of the mortar takes quite some time, it has been found to be a disadvantage that it is difficult to establish whether or not the mortar is set. In general, this method of assembly of the slide valve is greatly subject to human errors even if only the worn parts have to be replaced.
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.
It is a purpose of the present invention to provide a new and improved slide valve of the type mentioned above, whereby control of the parts of the valve and their flawless assembly is substantially eased in comparison with the known constructions, and whereby the influence thereon of human factors is substantially eliminated.
SUMMARY OF THE INVENTION This is attained in accordance with the invention by providing 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.
Preferably, 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.
Slide valves have become known wherein the orifice plate and the slide plate are assembled in the slide housing and this aggregate is then permanently attached to the jacket of the casting ladle. However, it was not recognized that such a construction can be used only under very special conditions. Therefore, these proposed devices did not yield any satisfactory results, especially for large steel casting ladles;
In contrast to the valves for gases or liquids employed in other fields, 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. This has two far-reaching consequences: the portions under the influence of the thermal expansion, which varies with time and location, change their original geometric shape, whereby thermal stresses which are variable in place and time are superimposed on the basic mechanical stresses. Thus, without compensation, for example, the originally precisely ground sealing surfaces of the valve would assume a convex shape during operation and would thereby lose their tightness of engagement.
Now it has been found that the only possible compensation for such deformation consists in the application of elastic deformation during operations of the parts forming the sealing and sliding surfaces, and that this is possible only if such parts consist of plates which are comparatively thin in relation to their extension. The preferable ratio of length to thickness ranges from 5:1 to 10:1. As a result of the generation of a variable temperature field pattern during operation, it was furthermore found to be essential that three force'couples be obtained as independently as possible, namely between the cover of the housing and the slide housing, between the slide housing and the bottom of the ladle, and between the orifice plate and the discharge nozzle. Only in this case can one ensure that, in a prefabricated and prearranged structural assembly, such as the slide valve in accordance with the invention, the superimposed thermal stresses will not add to the basic mechanical stresses in an uncontrollable and dangerous manner or cause relative motion of the parts endangering the safety of operation.
Finally, it has been found that the tightness of the joint between the slide valve and the ladle and the discharge duct therein, respectively, can be guaranteed for the construction in accordance with the invention if the position of the orifice plate in relation to the discharge duct sleeve is predetermined geometrically and cannot be modified either by the fastening of the housing to the ladle or by the tightening or loosening of the cover of the housing. This is especially valuable for the desired application of a dry mortar-free joint between the slide housing and the ladle and the orifice plate and the discharge duct sleeve, respectively, namely, by means of a refractory felt ring between the adjacent refractory parts and, if desired, an additional copperasbestos seal between the contiguous metal parts.
Under the described conditions, 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.
Even though mounting on the ladle of the completely assembled slide valve is preferred, 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.
BRIEF DESCRIPTION OF THE DRAWINGS A typical embodiment of the invention is described hereinafter with reference to the drawings, wherein:
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; and
FIG. 7 is an enlarged view in cross-section showing a detail of the sectional view shown in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT 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. In the example shown, 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. In order to firmly lock the slide housing 5 on the frame 4, there are provided two grooved bolts 8 (FIGS. 4 and 5) which project from the frame and into the grooves of which bolts wedges 9 (FIG. '3) can be driven, which wedges retain two perforated sidebars 10 placed on the bolts 8 when the slide housing 5 is in closed position.
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. While 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. For the sake of simplicity, only 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.
In order for the slide housing 5, together with all elements it contains to be removed from the joint pins 6 after the wedges 9 have been loosened, 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. During preliminary assembly, 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. This produces a ring shaped space which is sealed towards the outside and from which an inert gas, for example argon, can be delivered under pressure into the outlet of the ladle containing the melt. Both seals can be removed quickly and safely when the slide housing is disassembled.
The replacement of the slide plate of the design described above is limited to the few manipulations required for releasing and lifting off of the old slide housing and suspending and fastening of the new slide housing. This requires less than 15 minutes. Examination of the interior mortar joints and parts becomes likewise extremely simple in that towards such end, the slide housing need only to be pivoted away into the position indicated in dots and clashes in FIG. 1.
