In plate manufacturing, flatness has always been a challenging target as products are evolving towards harder materials along with increasing thickness ranges.
Clecim’s solutions are bringing flexibility from narrow to wide, from thin to thick, from soft to hardest grades to ensure processing the widest possible product mix.
In addition to having the premium flatness quality monitored by modern flatness gauges, the control of the Levelling process allows high plastification rates, ensuring minimized residual stress in plates as a result. This is advantageous in later forming and laser cutting processing stages, with consequential fewer rejections.
The process is optimized to ensure controlled throughput, preventing any bottlenecking, and whereas maintenance downtime is minimized by means of focused design.
Clecim Levelers are based on fully hydraulic actuation and ensures the safest control within machine limits. Our levelling control determines the best possible roll gap at all period of process based on torque and speed measurements. Using the actual torques and speeds, an intelligent algorithm generates commands for the entry and exit gaps and for each motor individually.
Independent control of the gaps and the motors is not always sufficient for processing the most demanding products. Precise torque and speed control for each motor is implemented in conjunction with the management of the HAGC hydraulic cylinders.
To achieve maximum knowledge of the material yield stress, Clecim has developed an observable neural network which adapts to the yield stress pass after pass.
To achieve the best dynamic behavior, the control system monitors jointly all actuators resulting in a high-precision control system.
