Moving Toward Visible Difference and Beyond: Imaging-Based Surface Quality Control for Rod and Wire

$15.00

Applications of rod and wire, particularly those subject to substantial processing, demand high surface quality to avoid product failure during processing or use. In recent years, imaging-based equipment has been applied not only to the hot rolling wire rod mills, but also in wire peeling and drawing facilities. The โ€œimage advantageโ€ provides the foundation of visibility, a key capability for detecting and verifying very fine surface anomalies. Additionally, the visibility also facilitates timely identification of process/equipment issues such as roll and die wear, among others.
