Implementation of a new quality flatness sensors in the distributed computer control systems of rolling mills

Abstract Quality manufacturing is very important in order to increase the steel industry competitiveness. For this reason, steel companies in the whole world has been investigating the ways to manufacture higher quality products. A new distributed system which is able to detect and measure flatness defects in rolled steel products has been developed. It is based on laser-optical principles, using lasers, line scan cameras and industrial computers. The new system will be integrated in the global DCCS of the rolling mill. In this way, the information is available for several computer systems in the factory.
