采用有限元法建立1500四辊平整机辊系变形模型,计算出弯辊力和轧制力变化对轧辊辊缝形状的影响。结果表明,工作辊弯辊和轧制力都能对辊缝形状有影响,工作辊弯辊对辊缝形状成正比变化,轧制力对辊缝形状成反比变化。 The finite element method was used to establish the deformation model of 1500 four-roll leveling machine roller system, and the influence of bending force and rolling force on the roll gap shape was calculated. The results show that both the work roll bending force and the rolling force can affect the shape of the roll gap. The work roll bending roll is proportional to the shape of the roll gap, and the rolling force varies inversely with the shape of the roll gap.
