本文从分析和实验上研究了因接触压力而导致轧辊表面的变形(沿轧辊轴向下降的图象)和轧板的鼓凸。半无限体的三维解完全适用于宽带轧制。当带钢既薄又硬,还增大其张力σ_2时,轧板凸度(h_(2,0)-h_(2,0.9))比以作用在带宽上的均布轧制力P计算的要小些。这个差值随推荐参数CMF={((?)P/(?)(△h)(h_(2,0)-h_(2,0.9))计-((?)P/(?)σ_2)σ_2}/P增加而增加,当CMF≥1时,实际上轧板凸度为零。这也说明,轧板凸度接近于零时的图象,可用考虑了接触弧长分布状态和入口座标的因素进行计算。
In this paper, the deformation of the roll surface (the image along the axis of the roll) and the bulging of the rolled sheet are analyzed and experimentally studied due to the contact pressure. Semi-infinite body 3D solution is fully suitable for broadband rolling. The strip crown (h_ (2,0) -h_ (2,0.9)) is calculated as the uniform rolling force P acting on the strip when the strip is both thin and hard and also increases its tension σ_2 Be smaller. The difference with the recommended parameter CMF = {((? P) (?) (? H) (h_ (2,0) -h_ (2,0.9) σ_2} / P increases, and when CMF≥1, the actual crown of the rolled plate is zero.This also shows that when the crown of the rolled plate is close to zero, the distribution of the contact arc length and the position of the inlet seat The subject factor is calculated.
