ABSTRACT:
A method and apparatus for rolling parallel-flange steel shapes under hot conditions through reversing rolling in a universal mill group are disclosed. The mill group comprises a first universal mill, an edging mill, and a second universal mill. The web height of the steel shape is finished to a final target size by a final pass in the second universal mill, or the inner web length is finished to a final target size by reducing the web weight by a first pass in the first universal mill before carrying out the reversing rolling.
