정상 압연 구간의 특징 값을 기반으로 한 판 파단의 상태감시

Tandem rolling mill has an important role in the steel industry, the improvements in thickness accuracy of a steel strip produced by a multi stand rolling mill are substantial interest to the steel industry. Because of the complicated equipment in order to improve quality and productivity, the necessity of appropriate condition monitoring is required. Condition monitoring should be able to decrease the cost of loss and equipment damage. This paper proposes one method based on the feature monitoring. High density of physical sensors to recognize a machine condition reduced monitoring efficiency. To increase the efficiency in high density monitoring is essential reducing the dimension of signal through statistic methods. This study performed the feature value method to the strip breakage at the stationary rolling region. This method can provide the dimension reduction and show the visualization.
