摘要
建立了圆截面轧扁时平均摩擦系数的推算方法;运用开槽法制作试样,研究设计了圆截面轧扁时平均摩擦系数测定的实验方法;进行了试验验证,取得了试验条件下的平均摩擦系数;在此基础上,总结出关于圆截面轧扁时摩擦系数的变化情况;研究工作对圆截面轧扁的定长轧制具有指导意义。
The paper deals with the matter to set up a calculated method of average friction coefficient when the circle section stick is rolled to flat; Using the sample with a cutting notch, the experiment method of average friction coefficient while the circle section stick is being rolled to flat is investigated and designed to exam the produced formulas and obtain the average friction coefficient under the currently condition. Then, the variable rule for rolling the circle section stick to flat are summarized, The research have a guidance sense to a fixed length rolling pieces being produced from circle section to flat.
