摘要

The compact-strip-production plant for the production of metal casting strip (200) as pre-product for slabs, comprises mold (110) for casting the casting strip, a vertical strand guide (120) for guiding and cooling the poured casting strip up to hardening, a bending- and aligning area (130) arranged downstream of the strand guide for bending and aligning the casting strip after its hardening from the vertical into horizontal, and a heat insulation element (140-n) arranged in the bending- and/or aligning area for the hardened casting strip. The compact-strip-production plant for the production of metal casting strip (200) as pre-product for slabs, comprises mold (110) for casting the casting strip, a vertical strand guide (120) for guiding and cooling the poured casting strip up to hardening, a bending- and aligning area (130) arranged downstream of the strand guide for bending and aligning the casting strip after its hardening from vertical to horizontal, a heat insulation element (140-n) arranged in the bending- and/or aligning area for the hardened casting strip, a temperature measuring device for detecting the temperature of the insulation element or of its surrounding, and an indicator and/or automatic evaluator for indicating and/or evaluating the detected temperature with regard to necessary exchange of the insulation element. The insulation element is arranged between two rollers in the bending- and/or aligning area in such a way that the interval between the side of the insulation element turned to the surface of the casting strip, and the surface of the opposite section of the casting strip, which is smaller than the diameter of the two rollers. The insulation element is coolably formed and has a carrier element on its side turned away from the casting strip, and a layer of insulation material on its side turned to the casting strip. The layer of the insulation material is mounted on the carrier element. The insulation material is formed from ceramic fiber with or without stainless steel film, technical insulation thread with insulating performance or from a heat shield. The insulation material is mounted over spacers to the carrier plate. The insulation elements are mountable and demountable in dependent upon the rollers and other elements of the bending- and/or aligning device. The insulation elements are fixable over fishplate hanging on the bending- and/or aligning device. A roller is arranged between the insulation element and the casting strip. The diameter of the roller is smaller than the diameter of the two rollers. The casting plant is operated with a casting speed of 3.5-8 m/min. The casting strip in the outflow of the aligning device has a cross-section with a width of 1000 mm and a thickness of 40-100 mm.
