At the reversing mill, rolling speed, roll bite, and coolant flow may be optimized only with a precise real-time knowledge of metal temperature. the low and highly variable non-greybody emissivity character associated with this complex aluminum process dictates the use of the most sophisticated multi-wavelength infrared pyrometers as the ...
The rolls can be ground to an hourglass shape. a 6-high mill also allows for substantial roll shape, depending upon the horizontal movement of the rolls. another advantage of a 6-high mill is a larger work roll which can transmit considerable torque and allow for high speeds up to 7,000 fpm.
Reversing pass, the work rolls were deviated hori-zontally toward the exit from the centerline of the backup rolls. the purpose of the deviation was to eliminate the clearance between the chocks and the mill window liners. since the single stand of a revers - ing hot roll mill is used for roughing and finishing
