  • Rolling mill roll eccentricity control
    Patent number: 4843854
    Abstract: 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 the backup rolls. One reason for this is to effect a compensation in the eccentricity of the backup rolls due to roll grinding.
