With the introduction of the hydraulically adjustable three-roll bar mill, a new chapter has been opened in the history of rolling mill technology. The innovative concept for the rolling-mill adjustment system is characterized by flexibility and speed. The computer-based technology system CARTA® supports the planning and optimization of the rolling operation. A wide range of different steel grades can be rolled more easily and quickly with the aid of this system. The rolling mill settings can be easily determined. The system furthermore helps with the tracking and with the utilization planning of numerous different roll ring sets.
