Scanners - Digitizers White Papers
Steel Identification is Moving Toward Bar Codes
Overview
Hand held laser scanners are widely available at relatively low cost. These units can read large bar codes at distances of up to four metres and may be radio linked to the mill's computer network for real time inventory and verification. The adjacent man readable number (ideally with a check digit) can be used as a backup when the bar code has been damaged. This permits reading at reheat furnace entry and offers the potential for reading from material handling vehicles or cranes in the storage yard.
Laser marking of paint patches is the newest approach to automated marking. Although it still has some of the maintenance problems of paint spray systems, it can provide vivid marks which can include man-readable characters and high quality bar codes, even on marginal fuzzy patches. Laser patch marking can be performed directly on hot products with one coat or on cold products with two.
