为解决粗轧轧制稳定性,减少轧辊异常报废损失,设计并应用了变接触支撑辊辊形和负凸度工作辊辊形。该辊系配置使得辊间接触长度与轧制带钢的宽度基本相等,消除了有害接触区,使辊间接触应力均匀化,并提高了辊缝横向刚度,改善了轧辊的磨损,增强了板坯轧制过程的对中和稳定性。 In order to solve the stability of rough rolling and reduce the abnormity scrap loss, the design and application of variable contact roll roll and negative roll work roll are designed and applied. The roller system is arranged such that the length of the contact between the rollers is substantially equal to the width of the rolled strip, the harmful contact zone is eliminated, the contact stress between the rolls is even, the lateral rigidity of the roll gap is increased, the wear of the roll is improved, Alignment and Stability of Billet Rolling Processes.
