Designed specifically for high-strength steel sheets with yield limits up to 1600 MPa. Advanced roller configuration and pressure distribution system ensures uniform leveling without material damage or surface defects.
Achieves exceptional flatness accuracy of 1.0-1.5 mm/m², eliminating warping and internal stress. Precision-ground 42CrMo alloy steel rollers with hardness HB260-280 ensure consistent performance and long service life.
Patented technology of separating roller driving and side roller adjustable design. Multiple rows of support rollers arranged in chess pattern maintain work roller rigidity and effectively level wave bending and scoop-shaped plate deformations.
Full-driven upper and lower roller system with dual motor drive ensures stable operation and emergency braking capability. Soft start device minimizes power grid impact while maintaining low noise and compact structure for continuous production.
Integral inclined iron adjustment mechanism allows manual fine-tuning of upper and lower leveling roller convexity. Easily adapts to correction requirements of various deformation types including wave bending and scoop-shaped plates.
Handles thickness range from 8-120mm and width up to 3000mm. Suitable for construction machinery, automotive manufacturing, and heavy equipment industries. Customizable for larger sizes and faster speeds based on specific requirements.
Reliable dual-motor system ensures stable, efficient operation.
Chess-pattern roller arrangement with adjustable convexity for superior leveling performance.
Heavy-duty welded steel frame construction with stress-relieved design ensures minimal deflection and vibration during high-load leveling operations.
Gcr15 quenched alloy steel rolls with hardness HRC 60-62, precision ground and polished for superior surface finish and long service life.
High-response servo proportional valve with closed-loop feedback system, providing precise roll gap control accuracy up to 0.01mm.
Yihai Controller with touchscreen HMI interface, intelligent parameter calculation, and data management for up to 2,000 material records.
