چکیده
This article deals with a red-scale measurement system which can be applied to Wire Rod Production Line in POSCO (Pohang Iron and Steel Company). A red-scale is a type of oxidized Fe coated on the surface of wire rod and as the name means it has red color. The main cause of red-scale is an improper control of cooling process after final milling stage. To control the cooling process we need to measure the amount of red-scale on the surface of wire rod and to feedback the information of red-scale to control unit. We developed a red-scale measurement system in which we used a color camera to get the information of the amount of red-scale on the whole of wire rod surface instead very limited spot information when we employ commercial colorimeter. This paper will explain the details of the structure of red-scale measurement system and its red-scale estimation algorithm Copyright © 2008 IFAC

An eddy-current-based sensor for preventing knots in metallic wire drawing processes
During metallic wire drawing processes, the presence of knots and the failure to detect them can lead to long production interruptions, significant economic losses and a lower quality of final product. Consequently, there is a pressing need to develop methods for real-time detection and prevention of this fault. In this paper a sensor to prevent the formation of knots during the metallic wire d...
