Definitions
- the invention relates to a starting device for a continuous casting plant, in particular for Round cast, according to claim 1.
- Starting devices for introduction into the continuous casting mold usually consist of a Ang manufactorelement and connectable to the Ancasting element via a coupling element Head of a cold strand.
- a corresponding starting device for round or profile casting is known.
- the head member has a smaller cross-section with respect to the mold on, after casting the dummy strand with the head member easily from the mold to be able to pull.
- the existing gap between the head member and mold is interposed a resting on the head member and the mold cross-section filling Sealed sealing element. This seal is necessary to prevent the passage of liquid metal to the head member and thus to avoid a merger with this.
- the mold is intensively cooled to improve the heat dissipation.
- the shed Strand is firmly connected after cooling with the starting device, so that About the connected with the starting device cold strand of the new hot strand one Driving and straightening system can be supplied.
- the casting element consists inter alia of a Pipe section, the opposite the inner wall of the continuous casting mold a circumferential Gap space forms. Between Ang manufactoring element and head member is a mold wall touching Sealing element arranged, which is present between the head member and mold wall Gap seals.
- connection of the coupling element with the pipe section is a through the Coupling element and the pipe section inserted transverse pin realizes the thus forming another part of the casting element.
- connection of the coupling element with the head member of the cold strand is done also via a cross member connecting both elements.
- the molten metal When casting a new strand, the molten metal enters the pipe section and the gap to the mold wall, whereby after cooling the melt a non-positive connection with the sprue consisting of pipe section and cross bolt and the upper part of the coupling element coming into contact with the melt is reached.
- this starting device has several disadvantages. On the one hand is the construction, consisting from a multi-part Ang manelement and a coupling element consuming in manufacturing and assembly, and the variety of parts incur additional costs the purchase and storage.
- this starting device has the disadvantage that the assembly and disassembly of the Connecting bolt between coupling element and head part of the cold strand very time consuming is. Another disadvantage is that the bolt after exiting the Continuous casting plant due to deformations due to operational stress or due to different thermal expansion is clamped in the coupling pin, that he can not be solved.
- the head member of the cold strand with the coupling element through Attached connected.
- the hanging is done via T-slots in the head section, with corresponding T-shaped counterparts engage positively on the coupling element.
- This device has the disadvantage that the production of the T-shaped connecting elements only very expensive to produce and uneconomical especially for Rundstranggelloanlagen and is impractical.
- the object of the invention is a starting device, in particular for Rundstranggelloanlagen specify that cost-effectively, easy to assemble and disassemble and without the described disadvantages of known devices.
- a starting device in which as essential Features the casting element and the coupling element made in one piece and the connection between the coupling element and the head member of the cold strand as light detachable and retractable hook connection is executed.
- the advantage of this starting device is that the one-piece design of the sprue and coupling element the manufacturing, assembly and storage costs and thus significantly reducing the costs of continuous casting.
- the casting element consists of a web-shaped Section whose kokkileitigen end portion is hook-shaped.
- the headpiece side End region of the web is designed as a coupling element.
- the molten metal filled in the cooled mold encloses the Web portion with the hook-shaped end portion, wherein the metal through the cooled inner wall the continuous casting mold undergoes intensive cooling.
- the through the hook shape realized undercut is advantageously a non-positive and positive Ensured connection between the decomposing metal and the An manelement.
- the hook shaped end portion of the Bridge be formed in an advantageous manner as a double or even quadruple hooks.
- this hook shape it is also conceivable further modifications of this hook shape, as far as they improved Connection of the casting strand to the Ang manelement are useful.
- the seal between the mold wall and the one with a smaller diameter provided head member of the cold strand necessary sealing element consists of an advantageous Embodiment of the actual the mold cross-section substantially filling Seal and a connectable to the coupling element metal plate.
- the metal plate has the task of the liquid metal in the head area near the heat to escape and to lead to a rapid solidification of the melt, which is made of flexible Material, preferably made of cardboard gasket, the sealing function between Mold wall and head member takes over.
- the metal plate is advantageous, independent in time pre-assembled arranged on the coupling element.
- the head member of the cold strand is formed on the connection side end as a hook, wherein the connection-side end the coupling element suitable for entanglement with the head member end formation having.
- This may for example also be a hook or a holding element, which can be encompassed by the hook of the head member.
- connection end as a hook
- connection-side end of the head member for hooking with having the coupling element suitable end formation
- the connecting region is in the misplaced connection side end portion of the head member, whereby it is achieved that the hook connection, for example, before metal splashes during the casting process as far as possible is arranged protected.
- connection side end portion of the head member is at the end with a provided over the entire diameter extending recess.
- the frontal End of the recess has on both sides of a hook forming paragraph and the end region of the coupling element to be connected for hooking into the recess suitable end area.
- This can be, for example, a bolt-like thickening be.
- this connection is subject to high mechanical stresses is, this paragraph wears relatively strong.
- this paragraph wears relatively strong.
- the paragraph is after a beneficial Feature formed as a separate connectable with the recess part.
- Figure 1 shows a starting device according to the invention for a Rundstrangg manstrom, the already assembled, placed in a mold.
- the starting device 1 consists of an inventively one-piece design of a Ang maniatas 3 and a coupling element 2, with a web 14 with each other are connected.
- the kokillen workede end portion 15 of the sprue element 3 is hook-shaped educated.
- the coupling element 2 is connected to the head member 9 of a non-illustrated Kaltstranges detachably connected via a hook connection.
- the sealing element 4 consists of a front side resting on the head member 8 and cardboard consisting of sealing disc 6, which seals the annular gap and a arranged thereon and slightly in diameter compared to the mold cross-section smaller metal plate 5.
- the metal plate 5 is before coupling the starting device 1 already preassembled on the head member 9 of the cold strand on the coupling element 2 arranged.
- the end region 15 of the sprue element 3 designed in this illustration according to the invention as a quadruple hook.
- the Ang hassleelement 3 with the hook-shaped end portion 15 together with the coupling element 2 is first produced as a burn-cut part of a flat plate, at the right angle to the two existing hooks two more hooks be welded.
- the bolt-like Thickened end portion 15 of the coupling element 2 comes after hooking the front side at the shoulder 13, 13 'of the recess 11 to the plant.
