Abstract

PURPOSE: The yield of products is improved by detecting the defect parts existing at the side edge parts, detecting the defects less than permissible defects, i.e., plate widths from which products can be taken and further measuring the length and thickness of the test material at these plate widths with good accuracy, in rough hot rolling operation.
