rolling process for a strip, especially a metal strip

摘要

The rolling process for a strip, and especially steel strip, sets a nominal strip thickness on entry into each rolling stand, and each rolling stand has a nominal thickness for the emerging strip. During rolling at a stand, the strip thickness changes in a transit zone (a4 asterisk ) from the entry to the exit thickness. The strip thickness is also changed in transit zones (a5 asterisk ,a6 asterisk ) at the following rolling stands between their entry and exit thicknesses. At each rolling stand, the quotient of the actual thickness nominal value and the actual entry thickness value remains constant.
