A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact, and sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because of other problems in a mill such as a power cut, mechanical problems of transportation or in the water2 Good tool condition (proper roll stepup, top and bottom roll root, proper radius and proper fin blade usage) 3 Proper mill alignment All shafts parallel to one another (all bottom shafts must be in the same plane and the weld box at proper height) and all shaft shoulders in line (breakdown thruCamber, The unkind Curve Welded Tube Pros

Fin Pass Rolls JMC Rollmasters

The fin blade is a narrow roll segment that fits into the open gap at the top of the partially formed tube As the rolls are adjusted together the metal is put into reduction (ie"squeezed") The flower images on this page represent the flower of a one inch diameter tube in the fin rolls If the original strip width is correct the scalp will grow to precisely load the first pass fin roll24/2/2014· On some, the top roll moves up and down to produce the desired angle; on others, the two bottom rolls move and the top roll remains stationary (see Figure 5) Another machine type is the tworoll, pinchstyle roll bender For this system, the tube feeds between an upper and lower roll, while on either side two adjustable guides move to produce the desired bend angle Many use roll bending toTube and pipe basics: How to achieve the perfect bend
