Rare End Control Device TRIZ Cases
- Roll Bender Pressure Control for Tail End Buckling Suppression
Continuous roll bender pressure reduction after tail exit keeps strip centered, suppressing meandering and buckling in tandem rolling.
- Stretch-Reducing Mill Speed Control for Tube End Thickness
Wall thickness feedback lets a stretch-reducing mill adapt motor speed profiles automatically to limit thickened tube ends and yield loss.
- Remote Rolling Mill Control Using Real-Time Model-Based Automation
Model-based automation and open-network signal transfer enable remote rolling mill control without sacrificing response time or operator safety.
- Rolling Mill Tail-End Leveling Using Thrust-Force Compensation
Estimated inter-roll and material-roll thrust forces correct tail-end load imbalance in rolling mills, improving meandering control and reducing buckling risk.
- Rolling Mill Zigzagging Control With Thrust-Compensated Leveling
Estimated inter-roll and material-roll thrust forces correct differential load data, improving tail-end leveling and preventing rolling mill damage.
- Tandem Cold Rolling Thickness Control Using Entry Thickness Transfer
Transferred entry thickness data lets upstream stand speeds be adjusted faster, improving delivery thickness accuracy under changing rolling conditions.
- Stretch-Reducing Mill Motor Curves for Tube End Thickening
Outlet wall-thickness feedback lets a Central End Controller tune motor speed curves to limit tube end thickening and reduce rolling losses.
- Rolling Mill Feed-Forward Speed Control for Stable Strip Entry
Monotonic feed-forward roll speed during strip entry reduces tension swings and material buildup, helping keep mass flow stable.
- Hot-Rolled Steel Sheet End Shape for Stable Coil Unwinding
A recessed fish-tail sheet end distributes unwinding load so thick, wide API X65 hot-rolled coils stay within coil opener limits.
- Rolling Mill Strip End Stabilization via Differential Force Correction
A computer unit calculates pivot values from differential rolling forces to correct roll positions and stabilize the trailing strip end during high-speed unthreading.
- Steckel Mill Reversing Unit Cold Head Control
Reversing unit ignores target thickness at the head end, monitoring current thickness and hardness to prevent faults from cold sections.
- Rolling Train Geometry Control via Neural Network Feedback
Higher-level automation measures actual strip geometry and calculates optimal parameters to prevent dog bone formations and reduce material waste.
