Development of Surface Inspection System for Wire Rod
نویسندگان
چکیده
This paper introduces the surface inspection system for wire rod in steel-making industry. The inspection system is based on vision technology. We have developed illumination system with blue LED lighting sources to get best quality of surface image. And we have implemented defect detection algorithms based on block sigma transform which can recognize wire rod objects and segments defect candidates from images in robust and efficient manner. We have installed the inspection system in production line and have good detection rates.

Intelligent Knowledge Based System Approach for Optimization of Design and Manufacturing Process for Wire-Electrical Discharge Machining
Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...

متن کاملOn-line Red-scale Measurement System for Wire Rod Coil
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 m...
