异径辊筒压延机速度分布及压力分布

Velocity and Pressure Distribution of the Calender with Non-equal Sized Rolls

本文采用双极坐标系,对异径辊简压廷机的流受理论进行了研究。得知,与同规格等径辊筒压延机比较,异径辊筒的体积流量增大,单位体积流量的能耗下降,辊筒横压力减少。且这种变化随辊筒不对称度的增大而加剧。

The rheological analysis of the calender with non-equal sized rollsis made by means of the bipolar coordinates.It is proved that in comparisonwith the normal one this new type of calender has more advantages:morevolumetric flow rate and less roll-separating forces e.t.c.And thesedifferences will be more obvious ith the increase of non-symmetricaldegree of the rolls.
