Cause Bending roller breakage

Cracking rolls Bending late, if after the design and operation are in line with standard stress tired roller reaches a certain number of cycles, it will constitute a stress concentration, leading to fatigue cracking; With suprasegmental overload stress increase this cracking is accelerated. Within the skill level, should try to raise the hardness of abrasion resistance to high rollers jobs, improve fatigue resistance, the same contact stress is reduced, the number of quality of life expected Bending roller is improved.
