Influence of roll neck design and inlet rolling temperature on roll neck service life
Roll neck fracture was the result of the rotational-bending fatigue due to uncontrolled decreasing of the inlet rolling temperature. Three groups of design modifications of the roll neck have been considered to decrease maximum local stresses and to increase roll service life. In order to reduce energy consumption, influence of three different inlet rolling temperatures has also been considered. The negative influence of rolling temperature decreasing on roll fatigue life can be completely compensated by adequate shape of roll neck and in that way reduce energy consumption and overall costs.
