EvalHD – High resolution process data for quality assessment

Initial situation

• Plant-wide quality databases exist at many steel producers
• Data-warehouses are optimized for per-coil data access
• For statistical analysis per-coil data aggregations are used
• No efficient aggregation of inner-coil quality information possible

Working topics

• Design and implementation of a dedicated HR data storage system capable of handling high-performance HR data access
• Development of a modular software system for product quality supervision supporting web-based access to HR data
• Implementation of this web-service at the industrial sites providing intuitive visualizations of the current production state

Results

• High-performance HR data access
• Through process synchronization of any kind of HR data
• Accelerated root-cause identification of quality problems
• Optimization of the whole production chain towards zero-defect production
