A method for producing a steel beam blank includes continuously casting a steel beam blank strand and cooling the steel beam blank strand in a secondary cooling zone. The steel beam blank strand is guided in a vertical casting plane along a curved path having its web perpendicular to the vertical casting plane, so that each of the lateral flanges has an intrados flange tip and an extrados flange tip. The method further includes straightening the steel beam blank strand behind the secondary cooling zone. When being straightened, the intrados flange tips are selectively reheated between the secondary cooling and the straightening of the steel beam blank strand via an external energy supply focused on the intrados flange tips. In this manner, transverse cracks in the intrados flange tips may be reliably avoided.

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.
