Abstract
Description
- The invention relates to a closing mechanism for a hole-bottomed container for dispensing molten metal and to a method of manufacturing such a closing mechanism.
- The closing element for a funnel originating from the bottom of a molten-metal holding ladle used to comprise an upward and downward movable stopper rod, which was coupled with a lifting bar extending across the surface of molten metal. The trouble here relates to guiding the stopper rod precisely to the taphole for closing the funnel after a molten metal pouring process. In addition, the stopper rod became rapidly worn in use.
- Due to these problems, taphole stoppers have since been replaced by slide gates, as described e.g. in
GB 2213412 A - On the other hand, publication
EP 0 332 867 A1 , included in the prior art, discloses a closing mechanism connected to the bottom of a container, wherein a funnel for pouring molten metal out by way of a bottom hole is established by rotating a hole present in a circular rod to the concentricity with a hole extending through the rest of the closing assembly. Such a structure is complicated and inconvenient, as well as expensive in terms of its manufacturing costs. - Further known from publication
WO 2005/042190 A1 is a metal-structured apparatus assembled from sliding plates, wherein the middle plate of a plate stack consisting of three plates is capable of being slid with respect to the upper and lower stationary plates for closing and opening a spout extending through the plates. The steel-fabricated plate stack has been assembled by means of a separate, erectable, bulky steel frame, which holds the entire package together. Such a structure is complicated and quite heavy, as well as bulky. - An object of the invention is to provide a closing mechanism adaptable to the holed bottom of a metal pouring ladle, which is devoid of drawbacks found in the foregoing closing elements, but which functions well also at high temperatures required by metal casting.
- The solution according to the invention enables manufacturing an economically efficient closing mechanism and having said closing mechanism integrated for a single piece.
- Advantages of the invention include simplicity, low manufacturing costs, and easy replacement of the assembly.
- The invention will now be described more closely with reference to the accompanying figures, in which
-
fig. 1 shows a closing mechanism in one embodiment of the invention, and -
fig. 2 shows a closing mechanism in a second embodiment of the invention. -
Fig. 1 illustrates aclosing mechanism 1 in cross-section. Theclosing mechanism 1 consists of three superimposedceramic plates hole 5. As shown infig. 1 , theclosing mechanism 1 is in a completely open condition when all threeholes 5 are in alignment along acommon axis 6. Displacing themiddle plate 3 relative to the upper andlower plates arrow 14, enables thehole 5 extending through the plates to be closed and the flowing of molten mass out of a hole-bottomed ladle to be stopped. - The plate package of three
plates ceramic frame structure 7, which in this embodiment extends continuously around the plate package over five sides, with the exception of a downwardpouring spout 8 which is aligned on thesame axis 6 as thehole 5 of the fixedly mounted lower and upper plates, and with the exception of atop surface 9 of theupper plate 2 which comes to bear against the bottom of a ladle (not shown in the figure). Around theframe structure 7 to be cast of ceramic mass is its metallic casting mold/outer housing 10, in which the plate package and refractory casting mass are placed in a manufacturing stage of theclosing mechanism 1. Adapted to set directly against the bottom surface of a ladle and its taphole in this embodiment is the plate package'supper plate 2. Theclosing mechanism 1 can be secured to the bottom of a ladle for example bybolts 11 and by brackets/washers 12 associated therewith. Theclosing mechanism 1 has itsmiddle plate 3 manipulated by means of aguide element 13 for opening and closing a pouring spout, as indicated by thearrow 14. As the cast structure is substantially airtight, there is provided anair conduit 17 for enabling a displacement of themiddle plate 3 from avacant space 16, said air conduit extending through theceramic frame structure 7 and themetallic casting mold 10. Thissame conduit 17 can be used for the expulsion of a material used during a casting process, a so-called filler/blocker, which prevents the casting material from reaching certain areas (the middle plate operating range). Useful as such a filler is any material familiar in casting technology, such as for example urethane, beeswax or the like. - Another option for attaching the
closing mechanism 1 to the bottom surface of a ladle is provided for example by clamp mechanisms, which are permanently fixed to the ladle's bottom surface and which can be released and secured for a simple replacement of the entire closing mechanism. An essential feature of the invention is thesimple closing mechanism 1, which is easy to replace as a single unit. - The
ceramic casting 7 is molded on at least two sides of the plate stack. In this case, the discussed sides of the plate stack would be those present in the viewing plane of the figure. The process can be continued from here in a stepwise manner with different variations for enclosing the plate stack on all six sides within the casting, of course with the exception of spots essential from the standpoint of operation (theair conduit 16, thepouring spout 8, a supply hole in the upper part of the structure for delivering molten mass to the plate stack, and a recess necessary for manipulating the middle plate). -
Fig. 2 illustrates aclosing mechanism 1 of the invention in a second embodiment. If desired, theceramic plates closing mechanism 1. Neither of the illustrated embodiments requires separate springs for pressing theplates ceramic plates - A
closing mechanism 1 according to the invention also enables designing embodiments, displaying one or more of the features described as follows: - the
casting mass 7 can be applied on just two sides, namely on both long sides of the plate package, - the
casting mass 7 can be applied not only on these two sides but also arbitrarily on one or more additional sides, including a top face and a bottom face of the plate package, - the
pouring spout 8 of theclosing mechanism 1, which leads out of theceramic casting 7 and the metallic casting mold/outer housing 10, can be fabricated also from aceramic bushing 18 and preset in contact with the lowermostceramic plate 4, whereby the ceramic casting need not be necessarily extended all the way to the mouth of the pouring spout (thebushing 18 shown in the figure in dashed lines), - 1-4 pieces of
support blocks 15 can be present in a position mounted arbitrarily on a vertical side perpendicular to the plate level of the plates. - The
ceramic plates refractory casting mass 7 with the assistance of the metallicouter housing 10. - The
closing mechanism 1 according to the invention is particularly suitable for use in association with molten steel (temperature about 1500°C), but it naturally useful in association with any molten metal (molten zinc 370°C). A limiting factor is the thermal resistance of ceramic plates, which is appr. 1600° in common commercial products used in association with steel casting processes. On the other hand, if plates are manufactured by using special ceramics, temperatures even higher than this can be reached. - A method of manufacturing the
closing mechanism 1 comprises the following steps of: - assembling a plate package, consisting of three finished
plates - aligning the plate package of three
plates casting mold 10 in a correct position by using necessary casting support blocks, - fitting the plate package with necessary plugging means for preventing the
ceramic casting 7 from reaching undesired sites (anair space 16 at the end of amiddle plate 3, anair communication 17 out of theair space 16 at themiddle plate 3, a pouring spout 8) by the application of methods known in casting engineering, - performing the casting of a
ceramic mass 7 at room temperature either in the position shown infig. 1 or alternatively in the upside-down position, - drying/curing the
ceramic casting mass 7 at room temperature for a period required by the casting mass (typically about a week) or, alternatively, using a casting mass good for dry pressing. - In addition to these steps, the method may, if necessary, involve one or more of the following steps:
- in case the
ceramic casting 7 is effected so as to cover also a top face of the closing mechanism 1 (the uppermost plate 2), the pouring spout can have its inlet end between the closing mechanism and the ladle fitted beforehand with necessary connecting bodies/seals to be embedded at least partially within the casting, - the final stage of manufacturing is performed by raising the temperature from about 400°C, the
casting mass 7 being vacated of possible water (the casting mass may also be originally water-free or it is possible to use for example masses which are good for dry pressing) and/or a so-called filling/plugging medium used in the mold. - It is obvious for a person skilled in the art that various embodiments of the invention are not limited to the foregoing example, but may vary within the scope of protection defined in the appended claims.
