Embodiment Construction
[0039] figure 1 The shown Stegel rolling mill 2 comprises: a reversing stand 4 with two work rolls 6 and two back-up rolls 8 between which a rolling gap 7 is formed; The feed side and discharge side of the coiler furnace are arranged, however figure 1 Only the tape winder furnace 10 on the feed side is shown. The Stegel mill 2, especially the reversing stand 4, consists of figure 1 The control and / or regulating device 9 shown symbolically in the figure is actuated.
[0040] In the coiler furnace 10 , the rolling stock 14 to be rolled, which is a metal strip in the illustrated exemplary embodiment, is wound up on a Stegel drum 12 . The rolling strip 14 is maintained hot in the coiler furnace 10 so that it can be rolled to the target thickness d by means of the reversing stand 4 ziel .
[0041] A general problem in such Stegel rolling mills 2 is that after a short time delay the material outside the coiler furnace 10 is already cold and can no longer be rolled completely to...

Abstract
The invention relates to a Stegel rolling mill (2) comprising at least one reversing stand (4) for rolling a rolling stock (14) and on the feed side and outfeed of the reversing stand (4) Side-arranged coiler furnace (10) for rolling stock (14). When rolling the rolling stock (14), the following steps are carried out by means of the Stegel rolling mill (2): Step 1 (S1): When rolling the rolling stock (14), at the beginning of the rolling stock (14) Neglecting the target thickness (d ziel) of the rolled piece (14) in the region; - Step 2 (S2): During the implementation of step 1, determine at least one value related to the current thickness (dist) and / or hardness of the rolled piece (14) Measure the parameter and compare it with the nominal value; - Step 3 (S3): When the determined thickness (dist) reaches or falls below the nominal value, taking into account the target thickness (d ziel) of the rolled piece (14) Run reversible racks. In the method for operating a Stegel rolling mill (2), cold, unrollable pieces of the rolling stock (14) are taken into account during the rolling process and the control of the reversing stand (4) is adjusted accordingly Or adjust so that disturbing events are avoided and the usable portion of the rolled stock is maximized.
Description
technical field [0001] The invention relates to a method for operating a Stegel rolling mill with at least one reversing stand for rolling a rolled stock and a Coiler furnace for rolling stock arranged on the material side. The invention also relates to a control and / or regulating device for carrying out the method, a Stegel rolling mill having such a control and / or regulating device, a machine-readable program code and a storage medium. Background technique [0002] In a Stegel rolling mill, the rolling stock, in particular the strip, exits the coiler furnace on the feed side and enters the reversing stand leading to the rolling track via a drive on the feed side. After the first rolling pass, the rolled stock is fed into the coiler furnace on the discharge side. During such a multiple-repeated reversal process, the beginning and the end of the strip are cooled more strongly than the central region of the strip. Stronger cooling results from the fact that the strip regio...
