Continuous improvement of production process with virtual rolling quality system

 

Customer: Rautaruukki Oyj

 CHALLENGE

A tandem cold mill must produce high quality products cost-effectively to maintain international competitiveness. Sheet metal industry customers require good strip dimensions accuracy and uniformity of the mechanical properties. The manufacturing of over 10,000 different steel grade/dimension combinations puts a lot of pressure on the rolling process, and continuous improvement of the setup models and process circumstances is needed.

 SOLUTION

VTT and Rautaruukki have created a virtual quality system to monitor and analyse the production process. The system uses virtual sensors and models to calculate quality features based on process information and analysed history data. The intelligent virtual-sensor technology is developed for estimating hard-to-measure variables. Automation system is continuously updated after analysis to achieve the required quality.
