Abstract

DC60 (12/03/47) Method for rolling and subsequent coiling of metal strips (1), especially steel strips (1) on the drum of the winder at The expandable is driven to rotate at least one (20) cylinder, in which the metal bar (1) is inspected in the longitudinal cross-section. To find the fault The normalization of the extrusion makes it possible to quickly and economically examine the sample of the metal strip (1a) in the continuous rolling process where the metal strip sample (1a) is directed along the extrusion line (2a) above the station. Roll (18), positioned below, goes to the inspection table (11) for unobstructed inspection and is then discontinued.Methods for rolling and subsequent coiling of metal strips (1), by Especially the steel bar (1) on the tank of the winder where The expandable is driven to rotate at least one (20) cylinder, in which the metal bar (1) is inspected in the longitudinal cross-section.

Claims (12)

1. The procedure for rolling and subsequent winding of a metal strip (1), specifically a steel strip (1), on the round barrel of an expandable winding machine driven to rotate at least one barrel (20), on which the metal strip (1) is inspected in its longitudinal cross-section for rolling abnormalities, is characterized by the sample of the metal strip (1a) being brought along the line of the rolling line (2a) above the lowered winding station (18) to the inspection table (11) for unobstructed inspection and subsequently stopped. 2. The method as specified in claim 1 is characterized by the fact that after the sample of the strip (1a) is cut, a new starting portion of the strip is deflected downwards under the inspection table (11) and is rolled onto the hopper of the upper hopper (20) or the hopper of the lower hopper (21). 3. The method specified in claim 2, which is characterized by the metal strip samples (1a) being decelerated by a belt conveyor (17) which are integrated into a single unit on an inspection table (11). 4. The method specified in any of the claims 1 through 3, which is characterized by the continuous rolling operation, is such that during the continuous rolling operation, the metal strip roll (25), the beginning of which is rolled onto the drum of the upper drum roll machine (20), is deflected 180 degrees and rolled to completion to the specified maximum diameter of the roll (25a). 5. The method specified in any of the claims in Claims 1 through 4, which is characterized by the roll of metal strip (25) being rolled down onto the lower drum of the drum winding machine (21), is lowered and passed parallel to the axis of the drum of the drum winding machine. 6. The plant for rolling and subsequent winding of metal strips (1), especially steel strips (1), is arranged after the production line to be continuous from the final production line (2) and contains an inspection machine for inspecting the metal strips (1) for rolling irregularities, which is characterized by the winding station (18) being arranged below the plane of the inspection table (11) which extends in line relative to the rolling line (2a), where the sample strip (1a) can be inspected independently. 7. The plant, as specified in claim 6, which is characterized by having at least one deflection unit (10) at the entrance (27) to the winding station (18) for deflecting the metal strip (1) to the drums of the winding machines (20, 21), is provided. 8. The mill as defined in claim 6 or 7, which is characterized by the winding station (18), is made up of the upper winding machine's drum (20) and the lower winding machine's drum (21), each drum arranged in a non-consecutive manner within the rotating frame (28) below the plane of the inspection table (11). 9. The plant, as defined in claim 8, is characterized by the upper drum roll bar (20) and the lower drum roll bar (21) being able to rotate on a diameter line passing through the central axis (28a) of the rotating frame (28). 10. A factory as defined in one of the claims of Claims 7 and 8, which is characterized by a diameter extending at an angle of approximately 15 to 25 degrees to the horizontal. 11. The plant, as defined in one of the claims of Claim 6 and which is characterized by a rotating frame (28) for the drum of the winding machine (20,21) is mounted on a rear support roller that is driven to rotate (29). 12. A plant as defined in one of the claims of Claim 6 and which is characterized by the contact roller arm (30) which may be rotated inward or outward and which consists of the contact roller (31) together with the bottom drum roller barrel (21).
