TRACEABILITY, quality and inventory control improve when barcodes are applied early in the casting and rolling areas, and scanned downstream.
Available from Nichol Industries , the barcode tags, developed by InfoSight Corporation of USA, can survive up to 1800°F even when attached to hot slabs.
Automatic tagging systems are available for slabs, blooms, and billets using white heat resistant tags with a laser printer receiving data and printing black barcodes and man-readable data with good contrast for scanning
Metal bars, rods and wire can also be tagged using a novel two step thermal transfer printer which produces tags capable of withstanding oven temperatures of up to 550°F or if attached with a wire up to 900°F
InfoSight Corporation has also developed a barcode scanner to read the labels to a distance of 15 metres which can be used from carriers or cranes to track material from casting to rolling.
Nichol Industries, the Australian agent, has a mobile exhibition of both the Laser and Thermal tag printers enabling steel manufacturers to have an on site demonstration and collect some test labels for trials.
