Experimental Research on Durability in Exploitation of Rolling Mill Rolls

Having in view the statistical data calculated for 10 years, the total consumption of rolling mill rolls represents 0 785...0 8 kg/tone of rolled steel. Nationwide, the 5 million tones steel being rolled every year represents a consumption of 4000 tones rolls, worth 6 million euro/year, which imposes large research with an important economic and scientific impact [1-6] It is noticeable that approximately 1/8...1/10 of the rolls are removed from exploitation because of the thermal shock caused breakings, which cause accidental damage and stoppage, and the losses expand over the rolls' cost, as well as production losses, disturbing the entire technological flux. , ,
