Resumo
As the economic conditions continue to remain unpredictable, the plate market is facing challenges that it has never seen before. For any new investment, the challenge is to design the plant such that it remains flexible to produce a wide range of products to cater for future demands. Siemens VAI’s latest references include a unique combination of Plate and Steckel Mills into a single line and a new Plate- Steckel Mill plant. These projects ensure both production flexibility of discrete plate and coil. One key component is the use of fully automatic thermo-mechanical rolling using the latest physical models and intelligent sequencing strategies achieves the optimum in grain refinement and thus improves mechanical properties. At the same time productivity is kept as high as possible through sophisticated mill pacing. The novel profile and flatness strategy relies on comprehensive physical models and makes use of SmartCrown® as a powerful actuator, enabling large reductions to be taken without risking edge waves. Throughout the rolling and cooling stages of processing, accurate calculation of the thermal-mechanical state of the plate is performed by the temperature and micro-structural monitors. This enables tighter control of the final plate mechanical properties by providing an insight into the plate evolution during the thermo-mechanical processing. This paper looks at the new technical features incorporated into these new mill lines.
