Sachgruppe der DNBAbstract
Based on the problem of a total evaluation of skip steel cables of blast furnaces two computer aided procedures for the analysis of the measured data of electromagnetic steel cable testing are developed. The first procedure is useful to detect inner and outer broken wires and simulates the analysis of a skilled inspector by a pattern classification algorithm using fuzzy-logic. Like an inspector this system has to be trained. This is implemented with the help of a genetic algorithm. The second procedure is helpful serves as evaluation of accumulated inner faults of steel cables. Therefore two characteristic values describing the inner condition are determined by frequency analysis of the measured data .
