| 摘 要： | 本文对无孔型轧制时的轧件稳定性问题进行了实验研究,分析了入口处导板对轧件稳定性的影响。在考虑入口处导板扶持轧件的情况下,研究了轧件稳定性随导板间隙系数、压下量、轧件高宽比以及轧件鼓形率等参数变化的规律。通过多元逐步回归分析,得到了轧后轧件最大歪斜的计算公式,由此推导了保证轧件稳定性条件时入口导板间隙系数的允许值。

| Abstract: | The stock stability in grooveless rolling was systematically inves-tigated to analyze the influence of entry guide on stock stability. Howthe stock stability changes with the guide gap coefficient, dranght,stock's aspect ratio and barrel ratio is discussed, taking account ofdifferent holding conditions of entry guide to the stock. Maximumskew of stock after rolling is calculated through multi-componentstepwise regression, thus giving the critical value of entry guidegap coefficient to provide the stability of the stock to be rolled. |
