Heavy-Duty Industrial Slitting Line with 36-Ton Capacity & Modern Controls
1. Heavy-Gauge Material Processing Capabilities
This industrial slitting line specializes in processing demanding thick-gauge materials from 1.0mm through 6.0mm thickness. The slitting line handles challenging substrates including high-tensile carbon steel and advanced zinc-aluminum-magnesium alloys. The slitting line's robust construction accommodates maximum 36-ton coils through the double-cone uncoiler, enabling continuous processing of heavy industrial coils. This slitting line maintains precision throughout its operational range, with all critical components engineered specifically for heavy-gauge capability applications requiring superior mechanical strength.
2. Core System: Double-Cone Uncoiler & Material Handling
The double-cone uncoiler forms the material feeding foundation of the slitting line. This double-cone uncoiler features an expanding mandrel design providing non-slip grip for 36-ton coils. The double-cone uncoiler integrates with a hydraulic lifting trolley system that positions coils for efficient loading. The hydraulic lifting trolley reduces manual handling requirements while ensuring precise alignment with the slitting line entry section. This double-cone uncoiler configuration enables rapid coil changes while maintaining operational safety standards for heavy materials.
3. Precision Entry & Leveling Subsystems
Material enters the slitting line through a sophisticated entry section:
2-roll pinch feed initiates controlled material advancement
5-roll leveler eliminates coil set and crossbow defects
Hydraulic crop shear trumps leading/trailing ends for perfect weld preparation
The 2-roll pinch feed works in concert with the 5-roll leveler to establish perfect flatness before slitting operations. The hydraulic crop shear features an 11kW drive motor for clean cutting of 6mm materials. This entry section ensures the slitting line processes materials with optimal flatness and alignment before reaching the cutting station.
4. Cutting System with High-Torque Transmission
The 260mm arbor cutting system delivers exceptional performance through:
Massive 260mm arbor shaft providing vibration-free operation
132kW arbor drive motor generating industry-leading torque
Anti-skip hold-down rolls preventing material displacement
The 260mm arbor diameter offers unparalleled rigidity during 6mm material separation. The 132kW arbor drive motor maintains consistent rotational energy even under maximum load. Anti-skip hold-down rolls apply controlled pressure to eliminate material vibration during high-speed cutting operations. This combination makes the slitting line's cutting system exceptionally capable for heavy-gauge capability applications.
5. Tension Control & Edge Processing Systems
The slitting line incorporates advanced material control subsystems:
3-roll tension unit establishes baseline strip tautness
Plate-type tensioner provides friction-based tension control
Dual independent edge trimmers process both edges simultaneously
The plate-type tensioner excels at maintaining consistent tension for thick 1-6mm materials. Dual independent edge trimmers allow customized edge treatment configurations while processing both slit edges concurrently. This slitting line configuration ensures perfect edge quality and dimensional stability throughout processing.
6. Bridge Unit & Scrap Management
The overlap bridge with integrated scrap chopper enables continuous operation during reel changes. The overlap bridge maintains material flow between the cutting station and rewinder while the scrap chopper processes trim waste into manageable segments. This overlap bridge design eliminates production stoppages during coil transitions, significantly boosting the slitting line's operational efficiency for heavy-gauge capability materials requiring frequent reel changes.
7. High-Capacity Rewinding System
Material recoiling features:
Ø610mm mandrel rewinder with exceptional core strength
200kW rewinder motor delivering precision torque control
Secondary hydraulic lifting trolley for coil removal
The Ø610mm mandrel provides rigid support for heavy finished coils. The 200kW rewinder motor enables tension-regulated winding from delicate threading to full production speeds. The hydraulic lifting trolley safely removes processed coils up to maximum capacity. This slitting line rewinding system builds production-ready coils with perfect tension profiles.
8. Control & Hydraulic Integration
The slitting line operates under the precision Eurotherm 590 DC Drive control system. The Eurotherm 590 DC Drive maintains tension accuracy within ±0.5% throughout all operational phases. Hydraulic functions are managed by reliable Huade solenoid valves and an air-cooled power unit that maintains optimal fluid temperatures. The Eurotherm 590 DC Drive interfaces seamlessly with all subsystems, creating a harmonized control environment for the entire slitting line.
9. Operational Readiness & Performance Guarantee
This slitting line delivers turnkey readiness with:
Comprehensive post-maintenance overhaul certification
Operational guarantee covering all subsystems
Eurotherm 590 DC Drive recalibration documentation
Hydraulic system pressure testing reports
The turnkey readiness status ensures immediate production capability upon installation. The slitting line's post-maintenance operational guarantee provides assurance of sustained performance for heavy-gauge capability applications. This turnkey readiness package eliminates commissioning delays for facilities processing zinc-aluminum-magnesium alloys and structural steels.
