METHOD AND DEVICE FOR DRYING AND KEEPING DRY ESPECIALLY COLD-ROLLED STRIP IN THE DELIVERY AREA OF COLD-ROLLING AND STRIP-ROLLING PLANTS

摘要

According to known methods for drying and keeping dry especially rolled strips (10), the dry area (34) of the finished rolled strip is separated from the damp area (35) of the rolling stand by a partition (12, 13; 14, 15). According to the invention, a contactless seal is created between the partition (12, 13; 14, 15) and the strip (10) by means of a compressed gas buffer which is similar to an air cushion and a split flow (31, 32). Compressed gas (33) is guided onto the strip surfaces at a right angle from above and below, from the nozzle lips (18, 19) of a number of blast nozzles (23).
