ZARIADENIE NA PÁSOVÉ LIATIEBAND CASTING DEVICE
Oblasť technikyTechnical field
Vynález sa týka zariadenia na pásové liatie, hlavne na pásové liatie ocele.The present invention relates to a belt casting apparatus, in particular a steel strip casting apparatus.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Hrúbka liatia pásu sa môže tak podľa požadovanej hrúbky hotového za tepla valcovaného pásu (1 až 3 mm) pri pásovom liatí ocele, ako aj kvôli dosiahnutiu dostatočných materiálových vlastností pri požadovanom tepelnom tvarovaní, vo veľkej miere optimálne zvoliť (napr. 10 mm).The strip casting thickness can be largely optimally selected (e.g. 10 mm) depending on the desired thickness of the finished hot-rolled strip (1 to 3 mm) in strip steel casting as well as in order to achieve sufficient material properties at the desired thermoforming.
Z DE 31 42 099 je známe zariadenie na plynulé liatie kovu, ktoré vykazuje prívodné zariadenie tekutého kovu, nosný pás pre tekutý a stuhnutý kov a bočné ohraničenia tesne dosadajúce na nosný pás. Bočné ohraničenia sú na nosnom páse upevnené na spôsob článkovanej reťaze.DE 31 42 099 discloses a continuous metal casting device which comprises a liquid metal supply device, a support strip for liquid and solidified metal and lateral boundaries abutting against the support strip. The lateral boundaries are fixed to the carrier belt in the manner of a chain link.
Takáto konštrukcia je technicky veľmi náročná. Hodí sa tiež v podstate len pre malé šírky pásu. Pri väčších šírkach pásu je pnutie v nosnom páse, vyvolané tepelným zaťažením, podstatne vyššie, ako u úzkych pásov, takže pri veľkých šírkach pásu nie je kvôli svojej tuhosti použiteľná konštrukcia reťazovo obiehajúcich bočných ohraničení.Such a construction is technically very demanding. It is also suitable in principle only for small belt widths. At larger belt widths, the stress in the carrier belt due to the thermal load is considerably higher than that of the narrow belt, so that due to its stiffness, the design of the chain circumferential boundaries is not applicable due to its stiffness.
U bočného ohraničenia, nehybného vzhľadom k smeru dopravy liateho pásu, prípadne nosného pásu, dochádza ojedinele počas procesu odlievania k prilipnutiu stuhnutej ocele. To vedie k rozsiahlym poškodeniam pásu a poruchám riadenia prevádzky, až k prerušeniu liatia. Podobné problémy vyvstávajú na privádzacom zariadení. Tiež na ňom ojedinele prilipne stuhnutá oceľ, čo vedie k rovnakým problémom.In the case of a lateral boundary stationary with respect to the conveying direction of the cast strip or the support strip, the solidified steel is adhered to occasionally during the casting process. This leads to widespread belt damage and operational control failures, even to casting interruption. Similar problems arise on the feeding device. Also, stiffly stiffened steel adheres to it, which leads to the same problems.
Vyvstáva teda úloha, vytvoriť zariadenie na pásové liatie, u ktorého sa spoľahlivo zamedzí prilipnutiu stuhnutej ocele na privádzacom zariadení a na bočných ohraničeniach.Thus, the task arises to provide a strip casting device which reliably prevents the solidified steel from adhering to the feeder and to the side borders.

Podstata vynálezuSUMMARY OF THE INVENTION
Táto úloha je riešená tým, že privádzacie zariadenie a/alebo bočné ohraničenia sú vytvorené kmitateľné, a sú spojené so zariadením na vytváranie kmitania. Prostredníctvom tohto opatrenia je možné zamedziť prilipnutiu stuhnutého materiálu.This object is achieved in that the supply device and / or the side boundaries are designed to be oscillative and connected to the oscillation generating device. By means of this measure it is possible to prevent the solidified material from adhering.
Podľa výhodného vyhotovenia sa kmitanie privádzacieho zariadenia a/alebo bočných ohraničení vykonáva v podstate kolmo k smeru dopravy pásu. Kmitanie sa pritom vykonáva tiež v rovine nosného pásu, prípadne odliateho oceľového pásu, avšak naprieč k smeru dopravy. To má tú výhodu, že konštrukčné náklady sú menšie ako pri kmitaní v smere dopravy, pri ktorom by bočné ohraničenia museli byť po celej dĺžke presne vedené. Okrem toho pri tomto vyhotovení s výhodou môže byť kmitanie v oblasti metalurgickej dĺžky (od oblasti odlievacieho otvoru až do stuhnutia pásu) optimálne nastavené, napríklad tým, že bočné ohraničenia sú v tejto oblasti rozdelené na jednotlivé úseky vždy s optimálnou frekvenciou a amplitúdou.According to a preferred embodiment, the oscillation of the feeding device and / or of the lateral boundaries is performed substantially perpendicular to the conveying direction of the belt. The oscillation is also carried out in the plane of the carrier strip or cast steel strip, but transversely to the conveying direction. This has the advantage that the construction cost is less than in the direction of travel, in which the lateral boundaries would have to be precisely guided along the entire length. Furthermore, in this embodiment, preferably the oscillation in the region of the metallurgical length (from the region of the casting aperture until the belt stiffens) can be optimally adjusted, for example, in that the lateral boundaries in this region are divided into individual sections with optimum frequency and amplitude.
Podľa ďalšieho výhodného vyhotovenia sú bočné ohraničenia uhlovo nastaviteľné. To sa týka ako protiľahlých bočných ohraničení, tak prípadne tiež úsekov usporiadaných vždy na jednej strane. Tým sa môže zlepšiť tiež rovnomernosť hrúbky odlievaného pásu po celej jeho šírke. Hlavne majú bočné ohraničenia sklon tiež proti kolmiciam k povrchu nosného pásu.According to a further preferred embodiment, the lateral boundaries are angularly adjustable. This applies both to the opposing lateral boundaries and possibly also to the sections arranged on one side. This can also improve the uniformity of the thickness of the cast strip over its entire width. In particular, the lateral boundaries also tend to be perpendicular to the surface of the support strip.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Podľa výhodného príkladu vyhotovenia pozostávajú bočné ohraničenia z vodou chladených dutých profilov.According to a preferred embodiment, the lateral boundaries consist of water-cooled hollow profiles.
Zariadenia na vyvolávanie kmitania sú s výhodou excentrické pohony, môžu sa však použiť tiež elektromagnety alebo hydraulické valce. Tvar kmitu môže byť medzi iným sínusový, zubovitý alebo lichobežníkový. Frekvencia zdvihu je napríklad 50 Hz pri zdvihu napríklad 0,5 mm. Prívod chladiacej vody sa vykonáva prostredníctvom flexibilnej trubice. Na kryte, ktorý je s výhodou usporiadaný nad odlievaným pásom, je kvôli utesneniu medzi bočnými ohraničeniami a krytom usporiadaná vrstva z tesniaceho materiálu odolného proti teplote, hlavne z plstiThe oscillating devices are preferably eccentric drives, but electromagnets or hydraulic cylinders can also be used. The shape of the oscillation may be, inter alia, sinusoidal, serrated or trapezoidal. The stroke frequency is, for example, 50 Hz at a stroke of, for example, 0.5 mm. The cooling water is supplied via a flexible tube. On the cover, which is preferably arranged above the cast strip, a layer of heat-resistant sealing material, in particular felt, is arranged to seal between the side borders and the cover.
31125 T z keramických vláken. Medzi privádzacím zariadením a nosným pásom je usporiadané príslušné utesnenie, pričom s výhodou je medzi nosným pásom a utesnením vsunutý ešte hliníkový plech, takže pri kmitaní nastáva relatívny pohyb len medzi vrstvou plsti a hliníkovým plechom. Privádzacie zariadenie a bočné ohraničenia sú s výhodou pridržiavané pomocou špirálových pružín.31125 T of ceramic fibers. A corresponding seal is provided between the feeder and the support strip, preferably an aluminum sheet is inserted between the support strip and the seal, so that relative oscillation occurs only between the felt layer and the aluminum sheet. The feed device and the side boundaries are preferably held by helical springs.
Podľa ďalšieho výhodného vyhotovenia môžu ohraničenia kmitať súčasne ako kolmo, tak tiež paralelne k smeru pohybu pásu (smer liatia), takže celkovo vzniká na hrane pásu šmyková sila pôsobiaca tiež v smere liatia. Kmitanie má s výhodou zložky vo všetkých priestorových smeroch.According to a further preferred embodiment, the boundaries can oscillate simultaneously both perpendicularly and parallel to the direction of movement of the strip (casting direction), so that a shear force acting generally also in the casting direction is generally produced at the edge of the strip. The oscillation preferably has components in all spatial directions.
Okrem toho môže kmitanie nastávať tiež kolmo k povrchu pásu.In addition, the oscillation can also occur perpendicular to the belt surface.
Podľa zvláštneho vyhotovenia sa kmitanie vyvoláva prostredníctvom úderov v pozdĺžnom alebo priečnom smere bočného ohraničenia. Tým sa môžu vytvárať pozdĺžne rázové vlny, ktorými sa prilipnutie môže efektívne uvoľniť.According to a particular embodiment, the oscillation is caused by strokes in the longitudinal or transverse direction of the lateral boundary. In this way, longitudinal shock waves can be generated by which the adhesion can be effectively released.
