外文摘要：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. (C) 2007 Elsevier Ltd.
