Definitions
- the present invention is directed to an apparatus for side sealing, particularly, but not exclusively, for narrow side sealing in belt or continuous casters.
- the publication EP 0 145 81 1 A1 discloses a caster with movable side dams. These side dams consist of individual blocks lined up on a band. By means of a device running alongside the blocks, the blocks can be sprayed with water on the sides facing away from the cast strip. Although such chain-like side dams can be relative robust, but have the disadvantage that their blocks can not always be sufficiently cooled or large amounts of water are needed, which in turn may need to be removed separately.
- the hoses may break or even rupture, which can endanger the operational safety if, for example, liquid steel can no longer be prevented.
- the quality of the band can be negatively influenced by uncontrolled outflowing water and on the other hand the cooling of the chain can no longer be ensured.
- Another disadvantage of this system is that in long cold chains or casting processes with high cooling demand, the pressure of the cooling water over the length of the chain is not sufficient, whereby the cooling for parts of the chain can not be adequately ensured. An increase in the water pressure in the chain is limited, because this has a negative effect on the closing force of the chain in the longitudinal direction.
- the aim of the present invention is to overcome at least one of the above-mentioned disadvantages.
- a device for (side-by-side) lateral sealing of a strip casting plant for casting a metal strip or strand is to be provided, which is more robust and / or easier to manufacture than the known systems and at the same time allows good cooling of the chain links.
- the invention comprises the features of claim 1, according to which a device is provided for laterally sealing a strip or strip casting plant comprising at least one chain with at least two successive metal blocks for laterally sealing the strip casting plant, the blocks forming links of the at least one chain and the device furthermore comprises at least one connecting part for connecting two successive metal blocks and a channel which can be filled with a coolant both through the at least two metal blocks and through the at least one connecting part.
- the connecting part according to the invention is essentially formed of metal and the device further comprises ball joints for connecting the at least two metal blocks with the connecting part connecting them.
- the compound according to the invention in particular increases the resistance to breakage of the device, wherein no demolition or breakage of a hose can occur more.
- both a high reliability and a high quality of the strand or the band can be ensured.
- the system allows an increase in the water pressure in the line compared to a system of flexible hoses.
- the mobility of the chain is ensured even at high pressures.
- the term lateral seal can be understood as meaning both a sealing of the narrow and broad sides of a band or strand or also the sealing of the upper and / or lower sides of such.
- the device can be used both in vertical casting plants as well as in horizontal casting plants.
- the ball joints each comprise a ball joint head and a ball joint socket and the connecting part has substantially the shape of a tube which at its two ends in each case comprises a ball joint head connected to the tube.
- the connecting part comprises at least one of the ball joints, wherein on the ball joint head one of the ball joint pans is movably mounted.
- the shape of the pipe or pipe cross-section is not limited to circular shapes and also polygonal or otherwise shaped cross-sections are covered.
- the ball joint socket movably mounted on the ball joint head is positively connected to the corresponding metal block for receiving tensile forces acting along the chain. Such a connection allows for a simplified assembly and / or interchangeability and on the other hand ensures an effective and stable connection of the metal blocks against tensile forces in the direction of the chain.
- At least one of the metal blocks comprises the ball joint socket (integral with the block or inserted or pressed into the block) of at least one of the ball joints.
- the at least two blocks are each formed from at least two detachably interconnected components (halves) such that the at least one connecting part is exchangeable.
- halves detachably interconnected components
- the connecting part or the tube between its two ends is formed divisible. Characterized in that the connecting part or the tube is formed divisible between its two ends, a ball joint or its pan or ball head can be replaced easier and faster. In the event of damage to a ball joint, material costs can be saved as well.
- the connecting part substantially in the form of a tube, which comprises at its two ends in each case one of the ball joints.
- the chain comprises a plurality of metal blocks and connecting parts for connecting successive metal blocks and at least one sprocket (preferably two sprockets), over which the chain is arranged circumferentially.
- the resistance to breakage of the device according to the invention over a system with flexible hoses is significantly improved.
- the device is designed such that the chain can run with the cast strip or strand.
- the ball joints comprise seals for sealing the ball joints against cooling water guided in the channel.
- the blocks and / or the connecting parts are made of copper or copper alloys and preferably made of steel, steel alloys or stainless steel. These materials have proven to be particularly suitable for the present device.
- the blocks may be formed of copper or copper alloys and / or the joints of steel or steel alloys.
- the invention also encompasses a strip or continuous casting installation comprising a device according to one of the abovementioned embodiments.
- the advantages of such a system essentially correspond to those already mentioned above.
- Figure 1 is a schematic, partial perspective sectional view of an embodiment of a chain according to the invention
- Figure 2 a schematic, perspective, partial sectional view of a
- Figure 3 a schematic, perspective sectional view of a
- Figure 4 is a schematic perspective sectional view of the connecting part according to Figure 3 in an angled position.
- Figure 1 shows a portion of a chain 1 of an embodiment of the invention for side sealing a strip or continuous casting, comprising a plurality of links or metal blocks 3.
- the blocks 3, which can also be referred to as dam blocks 3, are interconnected by connecting parts (or pieces or Through the chain 1 extends a coolant channel 7.
- This channel 7 extends preferably both through the blocks 3 and through the connecting parts 5.
- the channel can be expanded like a chamber for better cooling.
- cooling fins may be provided within the blocks 3 for better heat exchange with the coolant.
- the connecting parts 5 may substantially have the shape of a tube, whose cross section may be formed both round and square or depending on the application may have completely different cross sections.
- the connecting part 5 is connected by ball joints with the adjacent blocks 3.
- the connecting parts 5 at their (the metal blocks 3 facing) ends each comprise a ball joint head 9, wherein the channel 7 preferably extends through this head 9 and through the tube.
- the ball joint generally comprises a joint socket 1 1 or a joint shell 1 1, in which the joint head 9 is rotatably storable.
- the tube, the condyle 9 and the shell or pan 1 1 can form the connecting part 5.
- the Shell or pan 1 1 is provided fixed or detachable in the metal blocks 3.
- Figure 2 shows an enlarged view of a junction between two blocks 3, as already shown in Figure 1.
- the connecting part 5 connects two adjoining metal blocks 3. Through the metal blocks 3 and the connecting part 5 of the fillable with cooling water channel 7.
- the metal blocks 3 are preferably designed such that they receive the ball joint cups 1 1 positively. Tensile forces acting along the chain 1, the blocks 3 therefore already can not separate from each other. Other devices for receiving tensile and / or compressive forces or for sealing between adjacent blocks 3 can be additionally provided.
- Figure 2 also shows a preferred embodiment, according to which the connecting parts 5 are formed in two parts for separating in the longitudinal direction. The ability to share the connecting part 5 or the tube between the ball joints or the metal blocks 3, facilitates replacement of individual links of the chain 1 and the replacement of individual ball joints.
- the metal blocks 3 can be formed in such a multi-part, that they are open and so connecting parts 5 together with bearing or pan 1 1 can be seen.
- the joint sockets or shells 1 1 are preferably sealed relative to the blocks 3 and / or the rod ends 9 by seals.
- Figure 3 shows an inventive embodiment of a connecting part.
- the connecting part is essentially formed by a tube which comprises two telescoping pipe sections. At the ends of the tube, the connecting part 5 each has a ball joint shape.
- the illustrated shape of the ball joint head 9 is merely an example. In the context of the present application, the term ball joint is intended to be directed both to partially or hemispherical forms and to forms which form a complete sphere form.
- the cooling water channel 7 preferably passes through the condyle 9.
- the illustrated ball joint socket 1 1 may include a larger or smaller area of a condyle 9 or cover as shown.
- the metal blocks 3 are only inclined by less than 15 °, preferably less than 10 °, relative to one another.
- Rod ends 9 and pans 1 1 can be formed according to the maximum required tilt angles. If the connecting part 5 is formed divisible along its axis, if necessary, the two parts of the connecting part can be separated in the direction of its longitudinal axis, so that one of the two parts together with the joint shell 1 1 can be replaced or only one joint shell 1 1 can be replaced or even one of the parts including ball head 9 can be replaced.
- FIG. 4 shows the connecting part according to FIG. 3, in which the two joint sockets 11 are inclined by a few degrees. Such a situation may occur, for example, when a chain 1 together with the metal blocks 3 adjoining the connecting part 5 are deflected by means of a sprocket or a similar mechanism.
