| description | The invention relates to the technical field of steel rolling, and discloses a profile steel strip rough straightening method and system.The straightening method comprises the following steps that descaling and rolling are conducted on heated and discharged steel billets alternately, and descaling points are arranged at three nodes of heating and discharging, rough rolling and finish rolling of the steel billets; profile steel is formed after rolling is finished, and a rolling pull-down area is reserved; the descaled and rolled profile steel enters a cooling procedure to be subjected to cooling treatment; the cooled profile steel enters a straightening procedure to be straightened; and the straightened section steel rolling and pulling-down area and the straightening transition area are sawn. According to the method, the rolled pulling-shrinkage area is reserved, the rolled pulling-shrinkage area and the rolled pulling-shrinkage area are straightened at the same time, the straightness quality of the profile s |
