Definitions

  • the invention relates to a strip caster, in particular for casting metallic strips, especially made of steel.
  • Steel strips cast on the casting plant preferably have a thickness of up to 10 mm.
  • a casting system for casting steel melts in particular is described in DE 34 23 834 C2.
  • the liquid steel flows from a storage container through a nozzle onto an endlessly circulating, cooled belt that is supported by rollers.
  • the solidified strip is passed through conveyors of a subsequent plant for further processing, in particular rolling.
  • the solidified belt is still relatively soft and should in any case not be subjected to bending immediately after casting, for example after leaving the rotating belt, of the casting machine. There are also considerable temperature differences between the inside of the strip and the surface of the strip.
  • the object of the invention was to reduce thermal and mechanical stresses in the cast band.
  • a flexible support element is therefore provided in an arrangement adjoining the casting installation.
  • the flexible support element is stretched in particular between the casting plant and a subsequent conveyor.
  • the flexible support element absorbs the vertical forces caused by gravity.
  • the length of the support and guide element is adjustable.
  • Tensioned steel belts can be used as a flexible element, for example, which can in particular be mounted on rollers, wherein the rollers can be driven simultaneously or synchronously with the conveying devices. With the support element running along, the strip tensile forces can advantageously be minimized. The drive is controlled for this.
  • the flexible support element consists of a link chain in the manner of a bicycle chain, several chains being arranged next to one another in the direction of the bandwidth or these being interwoven with one another in such a way that they offer a sufficiently large contact surface
  • the flexible support element in particular the chain, has rolling elements.
  • These rolling elements can be designed as rollers or spherical elements rotating in the form of a roll. With these designs as well, the most important thing is to absorb the vertical forces and to ensure as smooth a transport as possible in the direction of movement of the cast tape.
  • the rolling elements are preferably rotating and / or in sections Longitudinal belt driven to avoid tensile and compressive stress in the supported area
  • adjusting devices for adjusting the tension of the flexible support element in its longitudinal direction are arranged on the flexible support element, in particular the supported belt or the preferred chain with rolling elements.
  • the slope curve and thus the length of the path supported by the flexible support element can be arranged
  • the flexible support element therefore also functions as a buffer for adjusting the belt tension. If the subsequent conveyor device has a higher speed relative to the previous one, the belt tension can be compensated for by shortening the flexible connector element and at the same time reducing the speed of the subsequent conveyor roller Conveyor roller reduces the tension on the flexible support element, thereby increasing the supported length and at the same time increasing the speed of the subsequent conveyor roller
  • the supported length of the flexible support element is preferably changed by adjusting devices which, in conjunction with suitable measuring and processing devices, can be adjusted in a controlled manner according to the torque of the idling roller on the casting installation
  • Tensioning rollers can be used as control elements in an endless circulating belt or chain
  • hydraulic hydraulic cylinders are preferably arranged at the belt ends or at a belt end.
  • a combination of a rotating belt with a supporting chain can also be provided
  • the casting installation according to the invention consists of a casting device 1 with an endlessly rotating belt, a compensating section 2 and a subsequent conveyor device 3.
  • the cast strand 4 is required between the conveyor device 3 and the roller 11 of the casting device 1
  • Compensating section 2 arranged the flexible support element 5.
  • the flexible support element 5 is designed as a chain with rollers.
  • the chain 5 is tensioned via support rollers 51 and chain tensioner 52.
  • the hanging curve of the chain 5 determines the length of the belt 4.
  • the belt 4 is practically aligned between the conveyors 11 and 3 in the dashed position. With reduced chain tension, the belt sags between the rollers 51 in accordance with the hanging curve
  • the tension of the chain 5 is regulated according to the torque on the roller 12.
  • the speed of the rollers of the conveyor device 3 is preferably also regulated by the control device.
  • the arrangement of a flexible support element is advantageous wherever the cast strand has to be supported in order to reduce vertical loads.
  • the flexible support element can therefore advantageously be used not only in strip casting systems, but also in casting systems for other dimensions.
  • the length of the support element is changed so that a constant, supporting force is exerted on the band lying thereon.
  • z. B. determines the force acting on the chain depending on the position. From the difference to the force measurement with a strand, the supporting force to be set as a controlled variable is obtained, taking into account the inertial forces.
  • the chain or the belt is rotatably supported at one or more points, so that two or more loops are obtained. This reduces the sag, and a binding of the support element, for example for setting a protective gas atmosphere, can have a smaller volume .

Abstract

L'invention concerne une installation de coulée, notamment de feuillards en acier. Le feuillard en acier coulé doit être soutenu, notamment après son passage à travers le dispositif de coulée, afin de réduire les tensions et les déformations mécaniques. Un élément flexible de support, notamment une chaîne à rouleaux, dont la longueur peut être modifiée au moyen de dispositifs d'ajustement appropriés, est monté à cet effet en aval du dispositif de coulée.
