摘　　要：阐述了变接触轧制技术的原理。从理论上分析了变接触轧制技术在提高承载辊缝横向刚度、增加弯辊力调控功效、改善辊间接触压力分布方面的作用。通过在宽带钢热连轧机上的长时间应用证明:变接触轧制技术可以显著改善轧后带钢的板形质量、降低轧辊消耗和增加轧制单位公里数。The principle of varying contact rolling technology is introduced. Theoretically the varying contact rolling technology can increase the transverse stiffness of loaded roll gap, heighten the control effect of roll bending, improve the distribution of contact force between backup roll and work roll. After long-term application on hot wide strip mills, varying contact rolling technology was proved to he effective in strip profile and flatness improvement roll consumption reduction and increase of rolled product length of rolling cycle.
