Roll System of High-Precision 23 roll leveler unlock ultimate flatness strip

Roll System for High-Precision 23 roll leveler

We proudly introduce our roll system for high-Precision 23 roll leveler, meticulously engineered for advanced production lines. This innovative system delivers exceptional material flatness through precisely calibrated multi-roll configuration and micro-stress elimination technology. Specifically designed to handle copper, aluminum, and specialty steel coils, it effectively eliminates common surface defects including ripple patterns, edge waves, and stress-induced deformations. The integrated precision control system ensures consistent quality output, significantly enhancing production yield by up to 25% while maintaining superior surface integrity for critical etching applications.

The advantages of the roll system for High-Precision 23 roll leveler are as follows:

The roll system is a key component of the leveler, whose main function is to support the working roll and intermediate roll, in order to minimize the deflection and deformation of the working roll. This ensures a stable impact on the production efficiency and quality performance of coils and strips. The key performance characteristics of the rolling mill during operation include:

• Enhanced Surface Hardness: Achieves superior surface hardness (HRC 58-65) through advanced heat treatment processes, ensuring exceptional resistance to abrasive wear and surface degradation in continuous operation.
• Optimal Full-Volume Hardness Uniformity: Maintains consistent hardness distribution (within ±2 HRC) throughout the entire roll volume via controlled quenching and tempering processes, eliminating soft spots and ensuring uniform wear characteristics.
• Deep Reinforcement Layer Technology: Features a substantially thickened reinforcement layer (15-25mm depth) within the roll body through specialized carburizing or induction hardening techniques, providing extended service life and sustained performance under heavy loads.
• High Strength & Impact Toughness: Engineered with superior mechanical properties in both roll neck and body sections, combining high yield strength (≥800 MPa) with exceptional impact toughness (≥25 J at 20°C) to withstand extreme operational stresses and shock loads.
• Outstanding Wear Resistance: Demonstrates exceptional resistance to abrasive and adhesive wear through premium alloy composition and advanced surface engineering, significantly extending maintenance intervals in high-friction applications.
• Superior Peeling Resistance: Incorporates optimized material structure and residual stress control to prevent surface spalling and peeling, even under cyclic thermal and mechanical loading conditions.
• Enhanced Sudden Load Resistance: Designed with robust structural integrity and fatigue resistance to withstand unexpected operational shocks and overload conditions, ensuring reliable performance in demanding rolling applications.
