Abstract

In the past few years, dramatic developments on the worldwide steel market and fierce, growing competition among the suppliers of steel products have led to massive changes in the steel manufacturing industry, such as: * Drastic reduction of personnel. *National and international mergers and acquisitions among steel manufacturers. *Increasing demand for automation of the production process. *New manufacturing processes (e.g. CSP or ISP production). Facing the ongoing challenge of cutting costs by increasing yield, resulting in a growth or at least preservation of the sales volume, steel manutacturers are demanding new automation technologies more than ever before. In order to be competitive on the worldwide steel market, steel companies must consider the installation of automatic surface inspection systems to be a key investment for more economic productivity. New developments in automatic surface inspection have not only lowered the initial costs for such a system, but also provide a higher level of pertormance. All data of the inspection results are available tor both immediate and long-term use for the production process control and quality control. Automatic surface inspection means: *Consistent, 100% coverage of the material surface at high production velocities up to 1200 m/min (24 hours / day - 365 days / year). *Objective and reproducible inspection results. *Reliable detection and reporting of the causes of production problems. *Immediate reaction time to allow the production process control to locate and eliminate problems. *Detect image capture, storage and interactive display to support automatic inspection. *Availability of all inspection data for statistics and analysis to establish improvement programs for the production process. Optimized and improved production process and quality control, especially with regard to ISO 9000. On-line quality control and process control, easily manageable by one operator (reduced personnel requirements). Two major developments have contributed to the increasing acceptance of automatic surface inspection systems: steel manufacturers have realized the economic importance ol automatic inspection, and suppllers of inspection systems have continually improved the performance of their systems. With new technologies and classification criteria, it is possible to meet the demands of the rapidly changing requirements in the steel manufacturing industry.
