Direct determination of sequences of passes for the strip rolling process by means of fuzzy logic rules

摘要

In this work the direct determination of sequences of passes for the strip rolling process by means of fuzzy logic rules is presented. The variables rolling load, accumulated deformation and aimed deformation - are expressed in linguistic terms, such as high, medium and low and their corresponding sub-levels. These rules can be established in agreement with data obtained from theoretical models, rolling of samples of the strip or by means of available databases for this particular material and operational conditions. In the last two cases, the procedure becomes independent of the knowledge of mechanical and metallurgical characteristics of the process.
