Product Introduction
This listing presents an exceptional opportunity to acquire a 99% new, Foshan-manufactured 750mm Cold Rolling Mill, configured as a high-performance 4-High Tandem Cold Rolling Line. Representing near-new condition at a highly competitive value proposition, this robust used cold rolling mill combines advanced engineering with proven reliability, engineered specifically for demanding precision metal forming applications. Designed to deliver superior thickness reduction, enhanced surface finishes, and consistent gauge control critical for producing high-quality strip products, this mill offers a strategic upgrade or expansion path for operations seeking high-volume output without the capital expenditure of brand-new equipment.
The core of this system is its sophisticated 4-High Tandem Cold Rolling Line (4-Stand) configuration. This sequential arrangement of four individual rolling stands is the cornerstone of its capability. Each stand progressively reduces material thickness under meticulously controlled conditions, ensuring uniform deformation and minimizing stress concentrations on both the strip and the mill components. This inherent design philosophy of the 4-High Tandem Cold Rolling Line translates directly into significant advantages: exceptional strip flatness, tight gauge tolerances across the entire coil length, improved metallurgical properties due to controlled work hardening, and superior surface quality compared to single-stand or reversible mills. The sequential reduction process is inherently more efficient, enabling higher throughput rates ideal for continuous production runs of precision strip in materials like carbon steel, stainless steel, aluminum, and copper alloys.
Power transmission is optimized through a Work Roll Driven system. Unlike conventional designs that drive the larger backup rolls, this configuration transmits torque directly to the work rolls – the rolls in immediate contact with the material. This engineering choice ensures maximum power delivery precisely where the deformation occurs, minimizing parasitic energy losses and effectively eliminating the risk of slippage between rolls. The Work Roll Driven system provides superior "bite" for initiating the rolling process, especially on harder materials or thinner gauges, and delivers consistent, high rolling force crucial for maintaining precise thickness profiles. This translates directly to reliable performance, reduced energy consumption per ton rolled, and enhanced process stability.
Complementing the drive system is the advanced Electric Screwdown mechanism for precise roll gap control. This system replaces traditional hydraulic or manual screwdowns with high-precision electric motors and actuators. The Electric Screwdown offers rapid, accurate, and highly repeatable adjustment of the roll bite (the gap between the work rolls) during both setup and dynamic rolling operations. Key benefits include:
Unmatched Accuracy: Enables maintenance of exceptionally tight thickness tolerances, often reaching micron-level precision.
Rapid Response: Quickly compensates for incoming material variations or process disturbances, ensuring consistent output quality.
Repeatability: Guarantees identical setup conditions for repeat production runs.
Simplified Maintenance: Eliminates hydraulic oil, associated leaks, and complex valve systems, reducing downtime and operational costs.
The mill is powered by robust and well-matched motors, ensuring ample power reserves for demanding cold rolling processes:
Main Drive Power: A high-torque 770 KW main motor provides the substantial power required to drive the Work Roll Driven system efficiently through all four stands of the tandem mill, handling the cumulative rolling force and maintaining required speeds.
Recoiling Power: A dedicated 355 KW recoiler motor delivers powerful and precisely controlled tension during the winding of the finished strip. This controlled tension is absolutely critical for achieving tight, stable, and vibration-free coils with optimal inner wraps, minimizing telescoping and edge damage, and ensuring safe downstream handling. Precise tension control also contributes significantly to final strip flatness.
