Popis: The key technology of the liquid core heavy reduction rolling mill relates to the roller’s normal life cycle in a bad work condition. It is the guarantee of continuous production. This paper simulated and calculated the two roller types which are built-up welding roller and roll-sleeve type roller, material of the rollers is H13 (4Cr5MoV1Si) which has better synthetical mechanical properties. It also calculated the fatigue life under the steady temperature, stress and strain fields after rolling for five cycles though the strain-life method.
