Metal Rolling Stand Details TRIZ Cases

Sensors profile work roll radius and hydraulic tilt correction reduces asymmetric roll gaps, preventing strip deviation and cobble risk.

A vertical switching frame alternates two forming units to speed steel pipe specification changes with less space, cost, and manual risk.

A compact support layout places X-ray thickness measurement between edge heaters, saving mill space while suppressing edge cracks.

Pre-rolling torque and vertical load balancing adjusts roll chock positions to suppress zigzagging, camber, and inter-roll thrust.

A staggered three-cylinder bearing layout cuts offset loads during large roll shifts, improving bending accuracy and bearing life.

Hot-state intermediate rolling plus on-line bending forms hat-shaped steel sheet piles while limiting flange waves, twists, and thickness variation.

A spring-damping interface decouples the rolling stand from the foundation to cut variable-frequency vibration, damage, and noise.

Hot rolling to a reduced height followed by on-line hot bending cuts passes, preserves temperature, and prevents flange wave and twist.

Heating a tapered work-roll end forms radial expansion that suppresses edge tight and plate breakage while improving edge drop control.

Pass-specific center flatness ranges guide rolling stand control variables to prevent flatness fluctuations, waviness, and instability.

Movable roll-drive extensions let all rolling cages be extracted from one side while avoiding angular gearboxes and water-prone gearbox placement.

Axially shifting hot rolling work rolls compensates running-surface wear, changing effective contour to maintain strip profile and planarity.

A dual-arm torque support transmits only tension and compression, preventing retroactive forces while allowing roller spacing adjustment.

A stationary stop and automatic position calculation calibrate vertical rollers faster, keeping personnel out of the danger zone.

Movable support bearings and roll offsets reduce horizontal load and free space for cooling headers, improving hard-strip rolling quality.

Small work rolls gain stable support through additional rolls and adjustable bearings, cutting conversion effort in cold strip rolling stands.

Offset support bearings create space for coolant headers while cutting horizontal roll force, extending bearing life and improving strip quality.

A fixed-bearing end-face support diverts axial forces from the work roll, reducing friction, wear, and heat in small-diameter rolling stands.

An arc-shaped plate and independent speed control enable very large diameter ratios while reducing friction, slippage, and strip warpage.

Axially arranged bending and backlash cylinders keep rolling mills compact while centering loads on bearing housings to reduce wear.

By varying friction or roll cross angle, this case identifies backup roll thrust working points without waiting for roll changes.

Optical sensors in oil feed and discharge lines detect coolant contamination and oil loss early in roll stand oil film bearings.

Separate sliding bending blocks and integrated roll shifting increase rolling mill stand opening capacity while simplifying roll change assembly.

Horizontal roller vibration boosts dislocation and oxide-layer breakup, improving metal clad plate bonding with lower deformation force.

Adjustable guide elements follow vertical roll movement to set offset outside the mill and prevent interference during rolled stock guidance.

Continuous casting, solutionizing, rolling, and quenching cut thick aluminum plate processing steps while preserving controlled temper.

Rotatable wear members with larger surfaces near the loop lifter spread strip-edge wear, cut manual cleaning, and reduce surface defects.

Adjustable horizontal support stabilizes a small work roll against lateral bending, improving roll stand rigidity for high-strength steel rolling.

Integrated hydraulic pressing units and oscillation absorbers brace mill stand rollers to cut stand vibration and improve hot-strip surface quality.

A double-ended balancing cylinder layout cuts seal loads in rolling mills, reducing leaks, wear, and cross-member stress.

Interchangeable work roll sets let one cold rolling stand match roll diameter to material strength, reducing flattening while preserving thickness reduction.

Vertically fixed bending cylinders and bending arms decouple roll gap adjustment from the backup roll balancer for high lift and easier maintenance.

Adjusting bearing support position preserves strip and roll clearances during wear, preventing interference while maintaining roll cooling and lubrication.

Adaptive gain control based on sheet width and measured shape prevents overcontrol and breakage in wide steel sheet rolling.

Contactless gas seals contain and remove roll coolant without wiper debris or cross-contamination, even during stops or reverse running.

Balancing work-side and drive-side rolling forces lets roll chock positions cut thrust, zigzagging, and camber in multi-high mills.

A motor-driven ball screw lift replaces hydraulics to keep roll press thickness uniform and avoid oil contamination inside glove boxes.

Integrated spray cooling within mill stands keeps steel section temperature uniform during passes while cutting rolling time and avoiding separate cooling zones.

Segmented bending blocks and axial roll shifting increase roll opening, stabilize thick-product rolling, and simplify mill stand assembly.

Intermediate coil storage decouples casting and rolling speeds, enabling hot-rolled aluminum strip without cold rolling or long homogenization.

Interchangeable support rollers let one rolling mill stand handle smaller work roll diameters without changing intermediate or backup rolls.

Alternating rolling stations enable same-side cartridge extraction while avoiding angular gearboxes, reducing maintenance and corrosion risk.

Grouped roll-stand offsets and a neutral stand reduce internal polygon formation, improving seamless pipe wall thickness and diameter tolerance.

Multiple roller units balance inner compression and outer stretching to bend angled thickness sections with less buckling, stress, and distortion.

Intermediate coil buffering decouples casting and rolling speeds, enabling faster strip production and controlled dispersoid formation.

Wireless smart modules sense roller guide position, manual tampering, and sound faults to automate calibration and cut rolling mill downtime.

Movable guide assemblies rotate with changing work piece curvature to resist twisting and improve bending precision without manual adjustment.

Multiple opposed roller groups vary peening force along the feed path to create uniform or graduated compressive stress profiles.
