摘要： 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.

摘要： 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.
摘要翻译：提出了一种从半成品H型钢束热轧Z型片材桩的方法。半成品H型钢的取向方式使得其幅材基本上平行于轧制平面。首先在第一多个轧制道次中轧制片材桩的预制件，以形成具有基本上平行于轧制平面的两个凸缘/幅材过渡部分的预制件。这两个凸缘/腹板过渡部将用于片桩凸缘的粗轧部分连接到与轧制平面倾斜的中间部分。在第二多个轧制道次中，由预成型件形成最终的Z型片桩。

摘要： An I-beam blank is rolled from a bloom by rolling into opposite edges of the bloom respective central triangular section notches of predetermined apex angle, apex radius of curvature, width, and height in a succession of roll passes. According to this invention the radius and apex angle of the notches are progressively increased a plurality of times during the succession of roll passes. Then the notches are pressed by rolling generally out of the bloom edges in at least one final rolling pass, thereby flattening these edges. The rolling passes are carried out between respective pairs of rolls having facing grooves bases and the roll pairs of the grooving steps are formed with respective triangular-section ridges complementary to the notches being formed. In addition the bloom is rolled repeatedly in the first pair of grooves until the material of the bloom flanking the notch mainly fills these grooves, that i until the bloom bottoms in the grooves.
摘要翻译：通过在一系列辊道中滚动预定顶角，顶点曲率半径，宽度和高度的相应的中央三角形切口凹槽的相对边缘，从花纹卷起一个工字钢坯。根据本发明，在连续的辊道期间，槽口的半径和顶角逐渐增加多次。然后，通过在至少一个最终轧制道次中通常从花纹边缘滚动来挤压切口，从而使这些边缘变平。在具有相对的槽基部的各对辊之间进行轧制道，并且槽对的辊对形成有与形成的凹口互补的相应的三角形脊。另外，在第一对凹槽中重复地滚动花纹，直到在切口侧面的花纹的材料主要填充这些凹槽，即直到花纹在凹槽中。
