TENSIONING ROLLER SETS ARE EMPLOYED IN DIFFERENT CONFIGURATIONS IN MANY PLANTS.
NUMEROUS INVESTIGATIONS ON STRETCHER AND ROLLER LEVELLING PLANT IN WHICH THE TENSIONING FORCES ARE APPLIED BY MEANS OF TENSIONING ROLLERS HAVE SHOWN THAT CONSIDERABLE PLASTIC STRETCHING OF THE STRIP CAN OCCUR NOT ONLY BETWEEN THE TWO TENSIONING ROLLERS (S-ROLLERS) BUT ALSO WITHIN THE TENSIONING ROLLER SETS IN UNCONTROLLED FASHION.
TO KEEP THIS EFFECT UNDER CONTROL IN PRACTICE AND USE IT FOR A GIVEN PURPOSE IT IS INTENDED TO ANALYSE THE RELATIONSHIPS BETWEEN THE MOST IMPORTANT PARAMETERS AND THE PLASTIC DEFORMATION OF STRIP PASSING THROUGH TENSIONING ROLLERS MORE ACCURATELY AND TO DETERMINE THEM QUANTITATIVELY.
SYSTEMATIC INVESTIGATIONS WILL BE CARRIED OUT ON THE EFFECTS OF FRONT TENSION AND REAR TENSION, THE TENSION LEVEL, THE DISTRIBUTION OF MOMENTS OVER THE INDIVIDUAL ROLLERS, THE NUMBER, CONFIGURATION AND DIAMETER OF THE ROLLERS ON THE DEFORMATION OF STRIP OF VARIOUS MATERIAL QUALITY AND THICKNESS.
THE INVESTIGATIONS WILL BE CARRIED OUT ON NARROW STRIP WITH A WIDTH OF APPROXIMATELY 200 MM. USING THIS NARROW STRIP THE ROLLER DIAMETER CAN BE SELECTED FOR THE TESTS TO BE SIMILAR TO THAT USED IN PRACTICE SO THAT PROBLEMS OF TRANSFERABILITY TO INDUSTRIAL SCALE BECAUSE OF DIFFERENCES IN DIMENSIONS WILL BE KEPT TO A MINIMUM. KNOWLEDGE OF THESE RELATIONSHIPS HAS PARTICULAR TECHNICAL AND ECONOMIC SIGNIFICANCE FOR THE LAYOUT AND OPERATION OF TENSIONING ROLLERS IN VIRTUALLY ALL CONTINUOUS STRIP MILLS.
