Description
<EMI ID=1.1> <EMI ID=2.1>
d'utiliser l'écart de l'épaisseur réelle du produit .laminé
<EMI ID=3.1>
but de modifier l'emprise de la cage, de telle sorte que l'écart d'épaisseur soit réduit à zéro.
Etant donné que l'on s'efforce d'utiliser d'une
<EMI ID=4.1>
éviter un surdimensionnement selon toute possibilité, le procédé connu pour la correction de l'épaisseur du produit laminé sortant est désavantageux, en oe sens que l'on doit dans chaque cas, concevoir la dernière cage de laminoir,
de façon que les grands écarts d'épaisseurs puissent également être encore surmontés.
La présente invention remédie à cette situation" ;
Elle consiste en ce que l'écart de réglage de l'épaisseur -. ;
<EMI ID=5.1>
la mise au point d'au moins la dernière et avant-dernière cage.
Dans le développement postérieur de l'invention, l'écart de réglage de l'épaisseur du produit laminé sortant est utilisé à la correction de la, mise au point de toutes
les cages du train de laminoirs..
Grâce à la présente invention non seulement une
<EMI ID=6.1>
la valeur moyenne de l'écart de réglage de l'épaisseur du ' . produit lamina sortant est utilisée à la correction de la mise au points.
L'utilisation de la -valeur moyenne de l'écart de
<EMI ID=7.1> , approximation, les -valeurs de correction peuvent également être proportionnelles aux, valeurs absolues de mise au point.
Dans un dispositif pour la mise en oeuvre du nouveau procédé de réglage de l'épaisseur, il est prévu des mémoires intermédiaires pour le maintien des valeurs de
<EMI ID=8.1>
cages de laminoir.
<EMI ID=9.1>
l'épaisseur du produit laminé sortant est titillai à la ^""
<EMI ID=10.1>
<EMI ID = 1.1> <EMI ID = 2.1>
to use the deviation from the actual thickness of the rolled product
<EMI ID = 3.1>
aim to modify the grip of the cage, so that the difference in thickness is reduced to zero.
Since we try to use a
<EMI ID = 4.1>
avoid oversizing according to any possibility, the known method for correcting the thickness of the exiting rolled product is disadvantageous, in that sense that in each case one must design the last rolling stand,
so that large differences in thickness can also be overcome further.
The present invention remedies this situation ";
It consists in that the adjustment deviation of the thickness -. ;
<EMI ID = 5.1>
the development of at least the last and penultimate cage.
In the further development of the invention, the adjustment deviation of the thickness of the exiting rolled product is used to correct the adjustment of all
the stands of the rolling mill train.
Thanks to the present invention not only a
<EMI ID = 6.1>
the average value of the thickness adjustment deviation of '. exiting lamina product is used for focus correction.
Using the mean -value of the deviation
<EMI ID = 7.1>, approximation, the correction values can also be proportional to the absolute focus values.
In a device for implementing the new thickness adjustment method, intermediate memories are provided for maintaining the values of
<EMI ID = 8.1>
rolling mill stands.
<EMI ID = 9.1>
the thickness of the rolled product leaving is titillai at the ^ ""
<EMI ID = 10.1>
