| Abstract: | This paper introduces the special pass schedule and technology for H-beam blank by splitting the cast slab. On the basis of considering the influence of pass shape and roll depressing on the spreading , the flange spreading and web spreading are calculated separately. Moreover, the corresponding formulas for spreading are brought forth against different pass shape and different pass. This formula can provide a good reference to theory research and practical production. |
