Title:
STEEL MATERIAL QUALITY DETERMINATION DEVICE AND STEEL MATERIAL QUALITY DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/061971
Kind Code:
A1
Abstract:
In order to make it possible to stably and accurately determine whether a steel material is produced from carbon steel or produced from low-alloy steel, provided is a steel material quality determination device characterized by being provided with: an image capturing means (11) which captures, continuously multiple times, images of sparks produced when a steel material (18) is rubbed; a detection means (12) which detects, from each of the captured images (2) captured by the image capturing means, an alloy spark region corresponding to an alloy spark produced by rubbing an alloy component contained in the steel material; a calculation means (13) which calculates the total number of alloy spark regions detected by the detection means; and a determination means (14) which determines that the steel material is produced from low-alloy steel when the calculated total number of alloy spark regions is a first threshold value or more, and determines the steel material is produced from carbon steel when the calculated total number of alloy spark regions is less than the first threshold value.
