In the process of rolling plate processing, we often encounter the situation that the cylinder produced by rolling appears big in the middle and small in the two ends.<br>We usually call this phenomenon barrel (drum) deformation.<br>For medium and thin plates with the same material properties:<br>The larger the plate width (the size along the length direction of the equipment) is, the smaller the diameter of the rolled cylinder is, and the easier the deformation is.<br>When the width of the plate exceeds 5m (in this case, the flat plate is welded and then rolled), the barrel deformation will be obvious.<br>
