Definitions

  • the invention relates to a strip caster with a melt feed and at least one Cooling device for cooling the melt.
  • Such a belt caster is known from EP-0526886.
  • Steel strips cast on a casting plant preferably have a thickness of up to 10 mm on.
  • a casting plant for the casting of steel melts in particular is also in the DE 34 23 834 C2 described.
  • the liquid steel passes through a through a storage container Nozzle on a continuously rotating, cooled and supported belt. That froze Belt is conveyed through conveyors of a subsequent plant for further processing, led especially rolling.
  • the solidified band is still relatively soft and should at least immediately after the shedding, for example after leaving the rotating one Band, the casting machine can not be subjected to bending. Also exist considerable temperature differences between the inside of the belt and the surface of the belt.
  • the object of the invention was to thermal and mechanical in the cast tape Reduce tensions.
  • the flexible support element is stretched in particular between the casting plant and a subsequent conveyor.
  • the flexible support element causes those caused by gravity Vertical forces added.
  • the length of the support and guide element is adjustable.
  • Tensioned steel strips, for example, can be used as a flexible element can be mounted in particular on rollers, the rollers moving along or synchronously with the conveyors can be driven. With the support element moving, you can the belt tensile forces are advantageously minimized. The drive is controlled for this.
  • the flexible support element consists of a link chain like a bicycle chain, in the direction of Bandwidth multiple chains are arranged side by side or so are intertwined that they have a sufficiently large contact surface Offer.
  • the flexible support element has so especially the chain, rolling elements.
  • These rolling elements can as rollers or spherical elements rotating in the belt conveying direction be trained. With these versions, too, it comes first and foremost to take up the vertical forces and one if possible smooth transport in the direction of conveyance of the cast tape guarantee.
  • the rolling elements are preferably rotating and / or driven in sections in the longitudinal direction of the belt to pull and Avoid compressive stress in the supported area.
  • the flexible Support element in particular the supported band or preferred chain with rolling elements, adjusting devices for adjusting the Tension of the flexible support element in its longitudinal direction arranged.
  • This allows the hanging curve and thus the length of the the flexible support element supported route can be set.
  • the flexible support element therefore also acts as a buffer for adjusting the tape tension. If the subsequent conveyor relative to the previous one a higher one Speed can be shortened by shortening the flexible support element while reducing the speed of subsequent ones Conveyor role of the belt tension can be compensated. Conversely, at too low speed of the subsequent conveyor roller the tension at flexible support element is reduced, thus increasing the supported length while increasing the speed of the subsequent conveyor roller become.
  • the supported length of the flexible support element is preferably by Adjusting devices changed in connection with suitable measuring and Processing equipment according to the torque of the idler roller are adjustable on the casting machine.
  • control elements In the case of an endless, revolving belt, as control elements or chain tensioners are used.
  • the casting installation according to the invention consists of a casting device with an endless belt, an equalizing section and one subsequent conveyor.
  • the shed strand is between promoted the conveyor and the role of the casting device.
  • Between the two conveyors is in the compensation section the flexible support element arranged.
  • the flexible support element is like indicated as a chain with rollers.
  • the chain is over Support rollers and chain tensioners tensioned.
  • the hanging curve of the chain determines the length of the tape. If the position is tense, the belt practically in the dashed position aligned between the Funding facilities and managed. With reduced chain tension the tape hangs between the rollers according to the hanging curve by.
  • the Chain tension regulated according to the torque on the roller In conjunction with measuring and control devices, not shown, the Chain tension regulated according to the torque on the roller.
  • the speed of the control device is also preferred Controlled roles of the conveyor.
  • the arrangement of a flexible support element is advantageous wherever the potted strand must be supported to withstand vertical loads reduce.
  • the flexible support element can therefore not only be advantageous Belt casting machines, but also for casting machines for other dimensions be used.
  • the length of the support element is so changed that on the tape lying a constant, supportive Force is exerted.
  • z. B the force acting on the chain determined depending on the position. From the difference to force measurement with a strand taking into account the inertia forces, this results as a control variable supporting force to be set.
  • the chain or band is attached one or more bearings rotated so that two or result in several loops. This reduces the sag, and a mounting of the support element, for example for setting one
  • the protective gas atmosphere can have a smaller volume.
