Definitions
- the invention relates to a system for producing a steel strip by deforming a cast steel strand consisting of a Continuous casting machine with an oscillating continuous mold cooled walls and a forming roller arranged at the mold outlet having deformation device for the steel strand.
- a system of this type has become known from EP-B1-0 326 190.
- This allows a thicker, void-free, in its thickness compared to the steel strand leaving the mold reduced strand with one also for further processing achieve fine-grained cast structure.
- the squeeze and press rolls of the Deforming device arranged at the mold outlet press the Steel strand together in such a way that the inner walls of the weld strand shells that have already solidified. Because of the small thickness of the emerging from the oscillating mold Steel strand and the subsequent reduction in thickness of the not solidified steel strand in the deformation device as well as at least one of these downstream rolling stands steel strands with a significantly less than 25 mm reach lying thickness.
- the invention is therefore based on the object in a generic Ensure that surface defects of the Steel strips due to one of the deforming rollers Have detoxifying and descaling devices avoided.
- the spray nozzles are arranged in a box-like housing are.
- the housing can preferably be resilient against the deforming rollers be employed.
- the enclosure of the spray nozzles ensures that the press water and the dissolved slag and scale particles are not get back onto the belt surface and thus into the roller gap. It can be an encapsulated removal of the press water and the Reach particles.
- the resilient employment of Housing that the roller surfaces in front and behind the nozzles are stripped so that on the surfaces of the deforming rollers adhering, not yet detached from the press water jets Scale and slag particles removed at this point at the latest and will no longer get onto the belt surface can.
- An alternative or additional measure provides that the spray nozzles the water as well as the scale and slag particles, internals preferably designed as discharge plates that follow the forming rollers in the direction of strand extraction, that is, are arranged below the rollers. Means of the discharge plates, the water and the contained Collect particles detached from the rollers and from the roller area remove before they fall on the rollers below or can get onto the belt surface again.
- box-like housings 6 are over the length of the squeeze and Press rolls 3, 4 distributed on the side facing away from the strand 5
- Stripped scale and Slag particles fall on internals designed as discharge plates 9, arranged from the steel strand 5 inclined to the outside and therefore the particles from the strand and machine area lead away. If the housings 6 were dispensed with, the Abströmbleche 9 also be sprayed away.
- the housings 6 and / or the outflow plates 9 thus ensure that the sprayed press water and the dissolved slag and Scale particles do not reappear on the surface of the steel strand 5 and get into the nips of the squeeze and press rollers 3, 4.
