| Abstract: | During rolling, there are mill roll breakage and pilling. Numerical analysis method, combined with cumulative damage theory, tolerable limit damage analysis theory and fatigue reliability analysis method, was applied to research mill roll reliability. Develop field variables of rolling pass, predict the life of mill roll and calculate the reliability of mill rolls. |
