1. Specialized Processing for Demanding 201 Stainless Steel Alloy
This cold rolling mill is meticulously engineered for the high-precision processing of 201 stainless steel, an austenitic chrome-manganese alloy known for its cost-effective corrosion resistance.
The cold rolling mill tackles the significant challenge of reducing 201 stainless steel strip thickness from a maximum entry gauge of 3.0 mm down to an ultra-thin finished thickness of 0.48 mm.
Precision thickness control across the full 680 mm strip width is paramount for successful 201 stainless steel processing, a core capability of this cold rolling mill.
Every design aspect of the cold rolling mill focuses on meeting the stringent requirements inherent to rolling 201 stainless steel efficiently and reliably.
The cold rolling mill's ability to achieve consistent 0.48 mm gauge exemplifies the 201 stainless steel optimization.
2. High-Power Hengli Motor System & Multi-Stage Gearbox Torque Transmission
Robust power generation is delivered by a Hengli motor system, featuring one 750 kW Hengli motor as the Main Drive and two 380 kW Hengli auxiliary drives.
This tri-motor Hengli configuration ensures synchronized power delivery and operational stability crucial for deforming 201 stainless steel.
The Hengli motor system transmits power through a high-torque gearbox arrangement: one 710 model gearbox (1:16 ratio) and two 500 model gearboxes (1:14 ratio).
These multi-stage gearboxes are essential for generating the immense torque required to achieve the specified 160 m/min rolling speed on 201 stainless steel.
The synergy between the Hengli motor system and the robust gearbox units provides the reliable, high-torque foundation necessary for efficient 201 stainless steel reduction.
3. Precision Roll Stack for Controlled 201 Stainless Steel Reduction
Precise deformation of the 201 stainless steel strip is achieved by a substantial and rigid roll stack.
The cold rolling mill employs large-dimension Work Rolls (Ø780 mm x 1600 mm body) in direct contact with the 201 stainless steel strip.
The Work Rolls are firmly supported by sturdy Backup Rolls (Ø750 mm x 650 mm body), ensuring minimal deflection under load.
The geometry and rigidity of the Work Rolls and Backup Rolls are critical for applying consistent, controlled pressure across the entire 680 mm width of the 201 stainless steel strip.
This robust roll stack design within the cold rolling mill guarantees the dimensional accuracy needed to achieve the target 0.48 mm finished thickness on 201 stainless steel.
4. Solid Mandrel Coiling for Critical Tension Stability in 201 Stainless Steel
Maintaining unwavering tension during coiling is vital, especially for ultra-thin 0.48 mm 201 stainless steel strip.
The cold rolling mill integrates a solid mandrel winding system for superior coil integrity.
The solid mandrel design utilizes a non-expanding shaft, providing absolutely rigid core support for the developing 201 stainless steel coil.
The inherent rigidity of the solid mandrel is fundamental for maintaining consistent strip tension throughout the entire winding process of the 201 stainless steel.
This tension stability provided by the solid mandrel prevents coil collapse, telescoping, or edge damage in the delicate finished 201 stainless steel product.
5. Eurotherm "590" DC Drive Control for Dynamic Process Accuracy
Overall governance and precision control of the cold rolling mill process are managed by the industry-proven Eurotherm "590" DC Drive system.
The Eurotherm "590" DC Drive delivers exceptional accuracy in both speed regulation and torque control, essential for 201 stainless steel rolling.
The Eurotherm "590" DC Drive ensures the cold rolling mill maintains the exact 160 m/min rolling speed while dynamically adjusting motor torque to respond instantly to variations in 201 stainless steel resistance.
This dynamic control accuracy from the Eurotherm "590" DC Drive is indispensable for achieving superior surface quality and consistent gauge tolerance on the 0.48 mm 201 stainless steel strip.
The Eurotherm "590" DC Drive system is the nerve center ensuring the cold rolling mill meets the precise demands of 201 stainless steel processing.
6. Integrated Heavy-Duty Platform for 201 Stainless Steel Excellence
Encased within a substantial 130-ton frame, the cold rolling mill provides the necessary rigidity and vibration damping for precision 201 stainless steel processing.
The cold rolling mill represents the seamless integration of the powerful Hengli motor system, the high-torque gearbox units, the robust Work Rolls and Backup Rolls, the tension-stable solid mandrel, and the precision Eurotherm "590" DC Drive control.
This synergy creates a formidable cold rolling mill platform specifically optimized for the efficient and high-quality production of ultra-thin 201 stainless steel strip down to 0.48 mm.
Every component of the cold rolling mill is purposefully selected and engineered to overcome the specific challenges presented by the 201 stainless steel alloy.
The cold rolling mill delivers proven performance and reliability for demanding 201 stainless steel cold rolling applications.
