Abstract

A methodology to determine the residual lifetime of continuous caster machine roll is developed. The roll is modeled as a thick-walled cylinder with a semielliptical crack. The study takes into account the statistical variation of the characteristics of cyclic crack resistance under operating conditions. The procedure enables to determine the parameters of acceptable distribution of crack depth for a given number of stress cycles and the distribution of durability for a given allowable depth of crack.
