| Abstract: | The application of multi-radius ellipse hole in No.1 Steel Rolling Mill of Shi Steel is introduced. The problems of end products being twisted and horizontal size too small are resolved with the last hole before finished of large-scale round bar changed from single radius ellipse hole to multi-radius one. |
