ABSTRACT:
A process and apparatus for producing increased reductions in strip material, particularly soft metal strip materials, are disclosed. The process and apparatus utilize a rolling mill having at least two offset work rolls driven at a peripheral speed ratio less than a desired gage reduction ratio but greater than zero and a mechanism for applying forward tension to the strip material. The desired gage reduction may be obtained using reduced separating force magnitudes and minimized tension force magnitudes. The rolling mill utilizes relatively small diameter work rolls without having to provide additional support structures other than the back-up rolls and frame roll supports to prevent roll bending in the rolling direction. Roll flattening is substantially eliminated resulting in improved gage control and strip flatness.
