Tandem rolling is an advanced process with high productivity and high quality product. But it is more complex than other rolling processes. It can be realized only when rolling theory, mechanical and electrical installations and control techniques have been developed to a certain level.The development of tandem rolling theory may be divided iuto three stages: classical tandem rolling theory based on the condition of constant mass flow; analytical theory of tandem rolling; and tension theory of tandem rolling.The principal contents of the theories are described briefly. Under the guidance of dynamic analytical theory the advanced full continuous and dynamic gauge changing rolling have been carried out.The author has analysed the dynamic gauge changing model shown by Fukuyama company which invented this advanced technique in Jap anand gives a calculation equation for setting. Some brief results of control model by simultaneously changing both the tension and the thickness are given.

连轧是一种先进的、具有高产、优质特点的轧制生产方法。但是,连轧比其它轧制方法复杂,必须在轧制理论、机电设备和控制技术发展到一定水平的条件下才能实现。本文把连轧理论的发展分成三个阶段:古典连轧理论——秒流量相等条件;连轧分析理论;连轧张力理论。简要地介绍了各理论的主要内容。在连轧动态分析理论指导下,实现了先进的全连续和动态变规格轧制。笔者对发明这一先进技术的日本福山动态变规格控制模型进行了分析,给出了设定计算公式,并给出了同时改变张力和厚度的控制模型研究的简要结果。

This ought to be the foundation of strength computation of driving pavts. Under certain conditions, cold strip...

The rolling theory deals with only simple rolling condition, but in fact, any rolling procees has, more or lees, some nonsymmetry For instance the diameters between two worle rolls are not absolutely equal This papes diecribes the experience on a four-high strip mill The tests proved that even a little difference between two xork rolls in diameters may cause unequal distribution of the rolling torque. This ought to be the foundation of strength computation of driving pavts. Under certain conditions, cold strip mill may use "single-roll drive and unequal diameter rolling" The practice proved that it could bring us three advantages: increase in reduction, decrease of the rolling pass and the saefty of driving parts.

根据轧制理论,在一般四辊轧机上轧制薄带钢时,常常认为相当接近于简单轧制条件,这时两轧辊的轧制力矩相等。测定表明,由于辊径不可避免地存在微小差别,接轴上的力矩常出现分配不均的情况,这应作为传动零件强度计算的基础。在一定条件下,冷轧带钢轧机实行“单辊传动,异径轧制”方案是可行的。实践证明它可保证轧机受力零件的安全,增加压下率,减少道次,从而提高轧机生产率。
