Abstract
A stand of a cold tube-rolling mill is formed by a housing and work rolls. Mounted in pairs on the housing are uprights arranged opposite to the axis of rolling. The work rolls are mounted one above the other in the bearing supports between pairs of lower and upper backup rolls mounted in corresponding bearing chocks. The upper bearing chocks are adapted for vertical setup motions. The stand has a device for ensuring positive contact of the work rolls. The device is a linkage mechanism for each bearing chock of the upper backup rolls that links kinematically the bearing chock with an independent power drive ensuring its vertical setup motion.
