An improved roll bending system is described for the work rolls and intermediate rolls in a six high mill. New bending blocks apply improved roll bending forces to the roll chocks, and additionally, are designed to move vertically and rotate, which provide important benefits to maintenance and enhance the rolling operation. Additionally, important related details to the mill operation and bending blocks provide operational improvements during roll changing.

Methods of shifting and bending rolls in a rolling mill

It is a primary object of the present invention to provide a pre-stressed rolling mill which has the advantages of a conventional mono-block mill housing and utilizes a standard Cluster mill gauge eccentric bearing gauge control system. It is highly desirable to have a rolling mill with a low cost mill housing design, a high mill stiffness, a simplified gauge control system, a capacity for multiple work roll ranges, and satisfactory side to side tilting. Such a mill is capable of operating satisfactorily as a commercial temper mill and a commercial cold mill.

Split housing cluster mill designed for temper and cold rolling

The present invention provides a Cluster mill which utilizes a Cluster mill gauge control system, has a high mill stiffness, a large work roll gap for threading, a rapid work roll gap opening, accurate roll force computation, side to side tilting, and utilizes work rolls over a much wider diameter range.
