The calculational formula of rolling pressure and moment was deduced by the three dimensional deformation analysis using the energy equilibrium principle. The experiments in cold rolling Al tube and hot roiling steel tube verified that the theoretically calculated value is identical with measured one, Thus, this formula seems to be available to the engineering practice. 收稿日期: 1983-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 朱之超 段振勇 温殿英 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I3/127 No related articles found!
