SUMMARY:Applications of imaging-based surface inspection equipment for process improvement at the wire rod mill of Třinecké Železány  
DESCRIPTION:In 2018 and 2019, Třinecké Železárny implemented a project to replace the surface inspection equipment using eddy currents in the two-strand wire rod rolling mills. The imaging-based surface inspection system was selected for installation in the wire rod mill based on its proven defect detection capabilities in many SBQ wire mills. The first unit was installed in 2018, with a second installation to follow in 2019. The wire rod mill quality team at Třinecké Železárny found the range of quality data, including images of defects, to be beneficial.  In addition to real-time detection and alarms resulting in mitigation of quality failures, the newly available surface quality data has led to the resolution of various surface quality issues and the development and implementation of a coil grading model based on customer requirements, wire diameter, material grades and surface quality data. The results of the quality scorecard, along with images of defects, are displayed on a large screen at the quality control station, providing all line operators across all mill shifts with a clear, consistent and repeatable assessment of the quality of each rolled coil. The introduction of imaging-based surface inspection systems, coupled with improvements to the rolling process that enable surface quality data, has contributed to the best quality performance in 2021 since the wire rod mill began operations in the mid-1970s. This document maps the processes, experiences and successes of surface quality improvement at the wire rod mills of Třinecké Železárny.
