通过对LD型冷轧管机轧制过程中芯棒轴向力的测试与分析,得到芯棒轴向力与道次变形量在宏观变形区上的分配有关。芯棒轴向力的分布特点,受轧制压力在宏观变形区上的分布和钢管不均匀变形程度的影响,其值由瞬时作用力和累积作用力两项构成:Q_(px)=F_(fx)+f_(x(q))。

The reductions distributed over the reducing zone are closely related with the axial plug force (APF) during rolling on the LD cold tube mill XIIFP60 The distribution of the APF is influenced by the rolling pressure distributed over the reducing zone and the inhomogeneity of fhe tube reduction The numerical analysis of APF indicates it may be the sum of a transient and an accumulated acting forces.
