Profile Control Device TRIZ Cases
- In-Line Slab Rolling Friction Control to Prevent Protrusion Folding
Rolling load and forward slip are used to hold slab rolling friction at 0.15-0.25, preventing protrusion folding and surface defects.
- Box-Section Rolling Profile Control for Stable Thickness Uniformity
A central-region contour control strategy keeps box-section rolled products uniform while avoiding concave profiles and unstable rolling.
- Casting Roll Crown Control Using Insulated Expansion Rings
Insulated heated expansion rings reshape casting roll crown during twin roll strip casting to maintain a stable strip thickness profile.
- Plate Crown Control Using Learned Roll Wear Correction
Real-time crown and flatness feedback corrects roll wear and thermal expansion errors to set bending force and shift values more accurately.
- Rolling Mill Profile Control for Stable Box-Profile Strip
Controls the strip center profile while accepting edge drop, preventing concave contours and stabilizing box-profile rolling.
- Protruding Mandrel Geometry for Hot-Rolled Coil Flatness
A center-protruding mandrel offsets thermal strain and tight winding effects to improve hot-rolled coil flatness and cut correction cost.
- Flatness Control Tuning via Singular Value Decomposition
Scaling the mill matrix by equivalent movement ranges enables singular value decomposition to eliminate null space actuator saturation.
- Metal Strip Profile Control via Buckling Strain Correction
A rolling control method adjusts strip profile using true elongation strain distributions derived from buckling analysis.
