摘　　要：国内大量应用的1 700mm以下的UCM冷连轧机组不具备工作辊窜辊功能,只能依靠工作辊边部辊形设计对硅钢板带进行边降控制。提出了针对UCM冷连轧机的工作辊端部辊形设计方法,在大幅提高边降控制能力的同时,通过边部保护段的设计有效减少断带风险。辊形曲线有利于轧辊磨削,避免轧辊表面质量对带钢表面造成影响。充分利用工作辊与中间辊弯辊的板形调控特性,使用高效实用的弯辊力组合板形控制方法,对轧制过程中产生的二次和四次板形缺陷实施快速精确的控制,在控制硅钢边降的同时很好地抑制板形问题,具有重要的研究价值与推广前景。UCM cold continuous rolling mills below 1 700 mm without the function of work roll shifting are widely used in China.So it can only rely on the contour design of the work roll edge to control the edge drop of silicon steel strip.A design method of work roll end profile for UCM cold tandem mill was proposed,which could not only greatly improve the edge drop control ability,but also effectively reduce the risk of breaking through the edge contour design with protective effect.The work roll curve is good for grinding to avoid the influence of the surface quality of the roll on the surface of the strip.The profile control characteristics of the work roll and intermediate roll bending were fully utilized,and the efficient and practical combination of roll bending profile control method was used to quickly and accurately control quadratic and quartic wave plate shape defects generated in the rolling process.The edge drop of silicon steel was well controlled while the flatness problem was solved.The technology has important research value and promotion prospects.
