International ClassesB21B 041/06B21B 039/08 AbstractA process for operation of a two-stand reversing mill optimizes product yield and time productivity in rolling strip in two or more passes through the mill, by bringing, in each pass, a tail end of the rolled strip to but not into the first roll stand through which the remainder of the strip has last been passed, gripping said tail end on a reel serving as an exit reel, rolling the strip and coiling it onto said exit reel. In a next to last pass after the first pass, a portion, e.g. about 1 1/2 wraps, of the strip may be left on a reel serving as an entry reel to maintain strip tension.Field of SearchWith modification or control of temperature of work, tool or machineIncluding cooling By means (other than a tool) modifying temperature of work Including optionally selectable work paths To reverse-roll the workpiece Comprising diverse roller-pairs Including successively-acting roller-couples Comprising relatively-inclined successive couples With carrier for roller-couple or tool-couple With replacement of tool Included in roller-cluster Including tautening of work during deformation (e.g., "tension bridle") | |
