Chapter 3 - Rolling of metals

• Hot mill can be provided with
facilities for crown control to
improve the control of the
profile of hot strip mill.
• For example work roll
bending with continuous
variable crown and pair cross
mills.
•The roll cross angle of rolls incorporated
in a stand of each rolling mill is set at a
predetermined value beforehand.
• If there is a roll cross angle that will
enable a target sheet crown to be applied
to each sheet and the roll bender load of
each stand is adjusted on-line, thereby
effecting sheet crown control.
