ABSTRACT:
Sheet steel profiles are rolled in a rolling line including a number of rolling mills. The starting material is first reduced and shaped conventionally in successive mills, and then the final rolling takes place initially by preliminary bending of the sheet steel profiles to the starting (first pass) shape. At this stage, the interlocking joint portion of the profiles are given a shape suitable for the finished profile. The finishing pass is then performed to give the profile cross-section its finished dimensions. All these final rolling operations take place continuously and in one direction.
