Designed for 3-20mm thickness where precision paramount. 15-roller full primary drive system provides superior distributed force. Achieves ±0.5mm/m² flatness unattainable by traditional equipment. Ideal for applications requiring near-perfect geometry post-leveling.
Both upper and lower work rollers actively driven by independent motors. Zero passive rollers = no slippage, superior surface finish. Each motor delivers 30-45 kW continuous power. Synchronization via proportional valve maintains<±2% torque variance.
Maximum precision configuration: 8 upper rollers + 7 lower rollers in alternating pattern. Reduces individual roller bending moment 60%, extends bearing life 3-4×. Optimal for thin-plate applications where precision, not throughput, is priority.
Four independent pressure transducers monitor inlet/outlet pressures continuously. PLC adjusts proportional valve position<100ms response time. Maintains constant pressure ±3 bar throughout rolling cycle. Achieves precision repeatability ±0.3mm across 100+ consecutive pieces.
4-row backup roller system with each support individually adjustable via wedge mechanism (±0.5mm per position). Eliminates beam deflection entirely. Maintains flatness tolerance independent of plate width or material variance.
System learns pressure curves per material batch. First piece rolled with operator-confirmed settings; system stores parameters. Subsequent pieces processed automatically with ML-based pressure optimization. Reduces operator training time 70%.
All 15 working rollers (8 upper + 7 lower) actively driven. No passive contact rollers. Each roller controlled independently via dedicated motor + proportional valve. Eliminates torque ripple, slip, surface vibration.
Four pressure transducers (inlet, outlet, upper, lower) send real-time signals to PLC. System continuously adjusts proportional valve spool position maintaining target pressure ±3 bar. Achieves precision repeatability ±0.3mm across full production run.
Q355 stress-relieved steel, closed-box construction. Deflection <0.3mm full load vs. 0.8mm standard equipment. Spring isolators reduce vibration 70%. Compact design optimized for thin plate processing.
15 independent SAI hydraulic motors (30-45 kW each). Individual planetary reducers ratio 1:80 per motor. Flow divider maintains ±2% load balance. 4-row backup roller matrix, individually adjustable.
Siemens S7-1200 advanced control module. 4 independent pressure transducers. 15 independent proportional spool valves. <100ms closed-loop adjustment. Stability ±3 bar maintained.
Industrial-grade Siemens PLC. 12-inch advanced operator interface. Absolute position feedback ±0.05mm accuracy. 6 emergency stops, dual-hand enable.

All 15 working rollers actively motor-driven. Traditional equipment typically has 3-5 active primary rollers + passive contact rollers. Full drive eliminates passive slip, improving precision to ±0.5mm vs. ±1.0-1.5mm standard.
Operator manually sets parameters for first piece. System learns pressure curve and stores it. Subsequent pieces processed automatically with predicted parameters. New material commissioning reduced 60%.
Full-load minimum radius: 200mm for thin-plate specialty. At half-load: 100mm achievable. 15-roller distributed-force configuration enables tighter radii than traditional equipment.
Optional configuration enables up to 150°C processing. Requires enhanced cooling + thermal insulation. Reduces required pressure 30%, extends equipment life under high-stress applications.
