Method and rolling train for rolling a rolled stock produced in an ingot casting process, open- and/or closed-loop control device for a rolling train, machine-readable program code for an open- and/or closed-loop control device, and storage medium

A method for rolling a rolled stock, produced in an ingot casting process, in a rolling train, where the rolled stock, prior to being rolled, has a truncated pyramid shape with a base area, a top area and four side areas, said method comprising:

• rolling, during a first rolling pass sequence, two opposite side areas of the rolled stock in a first direction, so that upon completion of the first rolling pass sequence, all cross-sectional areas of the rolled stock that are oriented transversely with respect to the rolling direction have identical surface areas;
• rotating the rolled stock;
• and
• rolling, during a second rolling pass sequence, the two opposite side areas of the rolled stock in a second direction transversely with respect to the first direction.

A rolling train for rolling a rolled stock produced in the shape of a truncated pyramid in an ingot casting process, comprising:

• at least one rolling stand for rolling the rolled stock in a first direction and in a second direction transversely with respect to the first direction;
• means for rolling the rolled stock in a first rolling pass sequence during which two opposite side areas of the rolled stock are rolled in the first direction until all cross-sectional areas of the rolled stock that are oriented transversely with respect to the rolling direction have identical surface areas,
• means for rotating the rolled stock from the first direction to the second direction;
• and
• means for rolling the rolled stock in a second rolling pass sequence during which the two opposite side areas of the rolled stock are rolled in the second direction transversely with respect to the first direction.

An open- and/or closed-loop control device for a rolling train, storing machine-readable program code which includes control commands that when executed cause the open- and/or closed-loop control device to perform a method for rolling a rolled stock, produced in an ingot casting process, in a rolling train, where the rolled stock, prior to being rolled, has a truncated pyramid shape with a base area, a top area and four side areas, said method comprising:

• rolling, during a first rolling pass sequence, two opposite side areas of the rolled stock in a first direction, so that upon completion of the first rolling pass sequence, all cross-sectional areas of the rolled stock that are oriented transversely with respect to the rolling direction have identical surface areas;
• rotating the rolled stock;
• and
• rolling, during a second rolling pass sequence, the two opposite side areas of the rolled stock in a second direction transversely with respect to the first direction.

A non-transitory storage medium embodying machine-readable program code that when executed causes a control device for a rolling train to execute a method for rolling a rolled stock, produced in an ingot casting process, in a rolling train, where the rolled stock, prior to being rolled, has a truncated pyramid shape with a base area, a top area and four side areas, said method comprising:

• rolling, during a first rolling pass sequence, two opposite side areas of the rolled stock in a first direction, so that upon completion of the first rolling pass sequence, all cross-sectional areas of the rolled stock that are oriented transversely with respect to the rolling direction have identical surface areas;
• rotating the rolled stock;
• and
• rolling, during a second rolling pass sequence, the two opposite side areas of the rolled stock in a second direction transversely with respect to the first direction.
