DEVICE FOR KEEPING A COLD-ROLLED STRIP DRY IN THE OUTLET OF STRIP ROLLING MILLS

摘要

The preferred quality requirements postulated by producers for the product cold-rolled strip include, among good flatness and optimum thickness tolerances, also dryness of the strip in the outlet of strip rolling mills. Already existing devices that are disposed in the outlet of roll stands comprise stationarily installed and mobile partitions, a roll barrel and a roll strip venting device and a vapor escape. The aim of the invention is improve the aforementioned device by disposing above the rolled strip ( 10 ) a strip deflector ( 3 ) with an integrated fan-operated strip venting device ( 4 ) by means of a low-pressure nozzle ( 7 ) and an upper roll barrel gap seal ( 5 ) in the form of a slotted nozzle ( 6 ) and below the rolled strip ( 10 ) an extraction device ( 16 ) with integrated lower strip deflector ( 17 )
