This paper addresses the problem of understanding whether certain process conditions of the Hot Strip Mill, Cold rolling mill and Hot-dip galvanizing lead to non-uniformities in the materials’ microstructure during the production of steel strip.
The work describes the application of an artificial intelligence technique (Self-Organizing Map) in order to relate the several process conditions with inline measurements by a Non-Destructive Testing system called IMPOC©. The influence on non-uniformity of some of these conditions has been investigated through statistical analysis on several different industrial cases.
SOM results can be exploited in Decision Support Systems to help steelwork operators to avoid, during the production, process conditions considered likely to end in materials’ non-uniformities giving them different feasible solutions.
