1964年5月间鞍钢的有关单位在小型厂成功地试验了一个结构简单的下开口正立围盘。通过立围盘的设计、制做与试验工作,我们体会到只要掌握轧件在围盘中弯曲运行的规律,围盘盘体与围盘装置就可以简化。简化后的盘体易于制做和满足设计要求,尤其以焊接结构代替铸钢件之后,更大大的方便了制做;简化的装置便利了安装与调整。本文重点介绍了盘 In May 1964, Anshan Iron and Steel related units successfully tested a simple-structured under-lip orthographic panel in a small factory. Through the design, manufacture and test of the flange plate, we realized that as long as we can grasp the law of the bending operation of the plate in the flange plate, we can simplify the plate body and the wall plate. The simplified plate body is easy to manufacture and meet the design requirements. Especially after the steel structure is replaced by the welded structure, the manufacture is more convenient and convenient. The simplified installation facilitates the installation and adjustment.
