本文按如下的出发点导出轧制压力的计算公式:(1)以平面压缩过程代替轧制过程;(2)接触面按不同摩擦规律分区;(3)采用非主轴坐标系的形状变形能塑性条件;(4)近似估计纵向应力σ_x沿板厚不均匀分布对轧制压力的影响。导出的计算公式可用于计算冷轧板带和热轧中、薄板的轧制压力。
The paper deduces the formula of rolling pressure according to the following starting point: (1) replaces the rolling process with plane compression process; (2) the contact surface is divided according to different friction rules; (3) the plastic deformation condition using non-spindle coordinate system ; (4) Approximately estimate the influence of inhomogeneous distribution of longitudinal stress σ_x on the rolling pressure. The derived formula can be used to calculate the rolling pressure in cold-rolled strip and in hot-rolled and thin-plate.
