Roll Grinder Monitoring
Steel and aluminum mills know that monitoring the roll grinding process for quality control improves the performance of work rolls and back-up rolls (BURs) used throughout the mill.
Work rolls touch all product surfaces that pass through a mill. Therefore, any pattern or lead line on these rolls is imparted onto the strip surface. Grinding chatter can lead to both 3rd and 5th octave mill chatter, which increases mill downtime and shortens roll life.
Today, advanced monitoring technology enables roll shops to dramatically reduce hidden roll surface imperfections. The direct impact on mill performance is significant. A recent study conducted by a major steel mill documented the elimination of unscheduled BUR changes coupled with a 7% increase in mill production.
