| Abstract: | Abstract： In this article, the design principles of finished hole, butterfly hole and slitting pass for angle steels are intro- duced. A set of pass graph for 25＂ large equal angle steel is designed based on the design features of rolling mill and blanks in Rail and Beam Plant of Baotou Steel. The practices prove that the pass schedule could produce products with three speci- fications at the same time, which could make the production costs reduced and the use ratio of rolls improved. |
