Abstract


The planning of cuts in steel rolls is a combinatory optimization problem. Some companies of the metallurgical industry use the steel cold lamination process so that it acquires the necessary physical properties. In this case, the cutting patterns should consist of compartments of items compatible with the lamination process, hindering the task of cuts planning. A compartment represents an intermediate roll to be laminated, so that it is possible to combine intermediate rolls with different lamination needs in the same roll of the stock. In this work the prototype of the RollCut System will be presented to aid with the cuts planning.
