| Beam Blank Deformation Characteristics during Open Pass Web Rolling
Takashi Kusaba, Toru Sasaki |

Synopsis : As an approach to clarifying complicated beam blank deformation characteristics during the open pass breakdown rolling into H-shapes, the deformation of dog bone beam blanks is studied using plasticine models starting with the web portion deformation behavior which is assumed to correspond to that of a flat plate under rolling force. Based on experimental results, mathematical expressions that can calculate the exact amount of metal flow and dimensions have been established to a level applicable to actual steel rolling. A new method of partial web rolling is also introduced. |
