Abstract: A system for controlling axial shifting of working rolls on a rolling mill is provided, and more particularly, a control system method which includes monitoring sensors for the rolling mill, processing information and calculating the non-all statical friction condition for the contact surfaces of the rolls on a central processing unit, and implementing the axial shifting of the working rolls on a hydraulic system. The purposes of roll shifting are primarily to control the strip shape and crown by improving the bending roll effect, to reduce the edge drop of the strip, and to maintain the uniform wear and thermal crown of the working rolls. In order to minimize or eliminate the scarring and scotch marks caused by axial shifting of the rolls, the contact zone must be kept in a non-all statical friction state. The non-all statical friction condition may be met by controlling the shifting velocity.

Abstract: A set of eccentric dowel pins and a pin-adjusted structure can move interlocking features of a hole type modular tooling system directly and continuously along axes without rigging and indicating, and thus provide full flexibility to such a hole type modular tooling system.
