PROCEDURE AND DEVICE FOR DRYING AND DRY MAINTENANCE SPECIALLY COLD LAMINATED IN THE EXIT REGION OF COLD LAMINATION FACILITIES AND FLEJES FACILITIES.

摘要

Procedure for drying and dry maintenance, especially of laminated bands (cold rolled strip), up to approximately 10 mm thick, preferably less than 0.2 mm thick, in the outlet region of cold rolling mills and strapping installations, in which for the separation of the wet space (35) from the rolling mill with respect to the remaining outlet region, behind the last rolling frame, the dry space (34), a bulkhead is arranged, the part of which upper is connected above the band to the bridge of the frame and whose lower part is connected below the band to the base plate, characterized in that the band (10) is driven with a gas, preferably air, under pressure from the ends of the band side of the bulkheads (12, 13) and their components (14, 15, 16, 16¿, 17, 17¿) from above and from below through blow nozzles (23) at right angles with with respect to the surface of the band, of so that a compressed gas mattress, similar to an air cushion, is formed over the entire width of the band, in the gap (30) of 0.1 to 1 mm, preferably 0.2 mm wide, between the bulkhead end (12, 13; 14, 15) on the side of the band and the upper and lower surface of the band and the compressed gas (33) is discharged above and below the band (10) in the form of an interstitial circulation (32) parallel to the surface of the belt in the direction of the rolling mill and the wet space (35), respectively and in the interstitial circulation (31) in the opposite direction to the dry space (34).
