Abstract
A method is presented for hot rolling a Z-section sheet pile from a semi-finished H-beam. The semi-finished H-beam is oriented in such a way that its web is substantially parallel to a rolling plane. A preform of the sheet pile is first rolled in a first plurality of rolling passes to form a preform having two flange/web transition sections substantially parallel to the rolling plane. These two flange/web transition sections connect rough-rolled portions for the sheet pile flanges to a middle section which is oblique to the rolling plane. A final Z-section sheet pile is formed from the preform in a second plurality of rolling passes.
