· Strip Width: ≤ 650 mm

· Yield Limit: 205 MPa ~ 850 MPa

3. Technical Parameters

· Threading Speed: 15 m/min

· Leveling Speed: 100 m/min (Max)

· Line Direction: Left to Right

· Tension in Bridle Section: 70 KN

· Equipment Centerline Elevation: +800 mm

4. Equipment Specifications

23-Roller Precision Leveler:

Primarily composed of the lower frame assembly, upper frame assembly, upper roll unit, lower roll unit, and sensor devices.

The flatness of the coiled strip heavily depends on the performance of the leveler. Prior to the strip entering the leveler, the Work Rolls are pre-adjusted based on the incoming material thickness and flatness status. If the flatness requirement is not met after passing through the equipment, the machine can be stopped (or kept running) for readjustment until the desired flatness is achieved.

1. Problems Solved

Elimination of Complex Shape Defects: Effectively eradicates critical flatness issues common in titanium processing, including edge waves, center buckles, and irregular coil breaks. This ensures the strip is perfectly planar before further processing.

· Mastering Ultra-Thin, High-Strength Materials: Addresses the challenge of processing difficult-to-work metals with extreme specifications (as thin as 0.05mm and yield strengths up to 850 MPa). The 23-roller configuration provides the necessary support and rigidity that standard levelers lack.

· Removal of Residual Stress: Eliminates internal stresses within the titanium strip, preventing distortion during subsequent cutting, stamping, or slitting operations and ensuring final part dimensional stability.

2. Objectives Achieved

· Achieving "Mirror-Grade" Flatness: The high-density roller arrangement and sensor feedback systems guarantee exceptional flatness, meeting the stringent requirements of high-end industries such as aerospace, medical, or precision electronics.

· Ensuring Production Continuity: With a maximum line speed of 100 m/min and a robust threading speed of 15 m/min, the machine maintains a stable tension of 70 KN. The pre-adjustment function minimizes downtime, allowing for rapid correction without halting the entire production line.

· Maximizing Yield & Versatility: One single machine handles a wide range of thicknesses (0.05–0.5mm) and yield strengths (205–850 MPa). This versatility significantly increases the equipment's Return on Investment (ROI) and reduces the need for multiple specialized machines.

3. Executive Summary

This equipment enables the customer to successfully achieve "Precision Processing of Ultra-Thin High-Strength Titanium Strip." It serves as the ultimate quality gatekeeper, ensuring flawless surface quality and structural integrity, thereby preventing downstream defects and maximizing the final product yield.
