在冷轧环件过程中需要控制进给速度，但首先必须进行计划。然而，到目前为止，由于现有方法效率不高，主要是通过试验和经验来确定的。本文旨在寻找一种简便的进给速度规划方法。本研究以圆环外径生长率作为确定进给速度的基准量。分析了轧制过程中环件膨胀的原因，建立了相应的数学模型。该模型定义了环件外径增长率与进给速度之间的关系。利用该模型对进给速度与轧环厚度的关系进行了规划。确定了进给速度的极值和环件外径生长速率的极值。根据环件外径增长率规划进给速度的方法是一种高效、经济的方法，有利于冷轧环件的工艺控制。
Feed speed needs to be controlled during cold ring rolling but first it must be planned. However, up to now, it has been set mainly by trials and experience, as the existing method is inefficient. This paper aims to find a convenient method to plan feed speed. In this study, the ring outer diameter growth rate was regarded as the basic quantity to determine the feed speed. A mathematical model is built on analysis of the reason for the ring enlargement during rolling. The model defines the relationship between the ring outer diameter growth rate and feed speed. Using the model, the feed speed was planned versus the thickness of the rolling ring. The extrema of the feed speed and the ring outer diameter growth rate were also determined. The method of planning the feed speed based on the ring outer diameter growth rate is efficient and economical, and it facilitates process control for cold ring rolling.
