<p>"Setting of a multi-stand rolling mill train for the cold-rolling of metal strip" To calculate process variables to be used in setting a multi-stand rolling mill train for a given strip, the strip is first classified into one of a plurality of predetermined thickness groups, in dependence on (a) the strip entry thickness, (b) the strip exit thickness and (c) the desired surface roughness on exit. Standard values for the selected class, relating to (a) reduction distribution, (b) deformation work and deformation force per unit width and (c) tensile stress, are then converted into adapted values by means of linear functions using the actual strip data values. The process variables are then calculated from these adapted values. This method is simple, but provides adequate precision for the setting of the train.</p> |
