US company Alton Steel Inc. has become the world's first steel producer to use Siroll Orbis+ to measure the profile of long products. The Orbis+ fully rotating, on-line gauge for wire rod and bar mills delivers improvements in both product quality and output, while reducing waste. Unlike traditional methods that merely sample a single side, the new device reviews the entire bar during the rolling process. So defects can be uncovered when they can be remedied instead of after the product is completed. The previous model, Orbis, has been used by Alton Steel since 1996.
Like its predecessor, the new Orbis+ measuring system works on the shadow principle and measures the dimensions and profiles of rod steel and rebar of different shapes, including round, flat, square, octagonal and hexagonal cross-sections. The new system can perform more profile measurements per unit of length than other systems available on the market and offers a high degree of precision.
