Rolling mill roll eccentricity control Kaiser Aluminum

The invention relates to the control of rolling mill backup roll eccentricity by combining the load carrying characteristics of rolling mill tapered roller bearing assemblies during rolling with prescribed levels of axial thrust to effect a controlled deflection of backup roll necks on a 4-high rolling mill or the like due to the selected thrust force applied axially to the ends or necks of
