| Category | Item | Detailed Description |
|---|---|---|
| 1. General Overview | Equipment Identity | This is a well-maintained 900mm 6-Hi Cold Rolling Mill, manufactured in 2012. It represents a modern, high-precision reversing mill designed for efficient cold rolling of mild steel strips. The equipment is supplied by Keepwin Industry, a professional used metallurgical solution provider, ensuring comprehensive technical support and services. |
| Manufacturing Date | The mill was manufactured in 2012, making it a relatively modern asset with contemporary design features and good remaining service life. | |
| Mill Configuration | The mill features a 6-high roll configuration, which provides superior rigidity and strip shape control compared to traditional 4-high mills. This configuration is ideal for producing high-quality cold rolled strips with tight thickness tolerances. | |
| 2. Mill Type and Configuration | Number of Rolls | The mill stand contains 6 rolls per stand: two work rolls, two intermediate rolls, and two backup rolls. This arrangement minimizes work roll deflection and enables precise thickness control across the strip width. |
| Roll Arrangement | The 6-high configuration positions the small-diameter work rolls in direct contact with the strip, supported by intermediate rolls and large backup rolls. This provides exceptional rigidity while allowing for significant reduction per pass. | |
| Designed Rolling Materials | The mill is specifically designed to process Mild Steel (MS) , making it suitable for a wide range of commercial cold rolling applications including general stamping, forming, and light industrial uses. | |
| 3. Product Dimensional Capabilities | Minimum Finished Thickness | The mill is designed to produce finished strips down to an impressive 0.15mm minimum thickness. This thin-gauge capability makes it suitable for precision applications requiring light-gauge cold rolled steel. |
| Actual Production Width | The original owner successfully rolled strips up to 820mm actual width, demonstrating the mill's capability to handle medium-width materials efficiently. | |
| Actual Minimum Thickness | Production records confirm the mill consistently achieved the designed minimum thickness of 0.15mm in actual operation, validating its precision capabilities. | |
| 4. Speed and Performance | Maximum Rolling Speed | The mill achieves rolling speeds up to 400 m/min, providing excellent productivity for medium-width cold rolling operations. This speed capability ensures efficient throughput for both small and large production runs. |
| Production Efficiency | The combination of 6-high rigidity, powerful drives, and 400 m/min speed enables high productivity while maintaining excellent strip quality and dimensional accuracy. | |
| 5. Drive and Power System | Main Drive Motors | The mill is powered by two 800kW main motors, providing substantial rolling torque for effective reduction. The dual-motor configuration ensures balanced power delivery to the mill stand. |
| Coiler Drive Motors | Both coilers are equipped with two 800kW motors each, ensuring precise tension control during high-speed rolling. This powerful coiler drive system maintains stable strip tension, which is critical for achieving good strip shape and thickness consistency. | |
| Power System Configuration | The comprehensive drive system, combining main and coiler motors, delivers total installed power of approximately 4,000kW, ensuring ample power for all rolling conditions. | |
| 6. Control and Automation | Electrical Control System | The complete electrical control system is reported to be in good condition, ensuring reliable operation and precise coordination of all mill functions including speed, tension, and screw-down positioning. |
| System Integrity | All control components are present and functional, with no missing parts reported. This ensures the mill can be operational quickly after relocation and installation. | |
| 7. Material Handling | Coiler and Uncoiler | The mill is equipped with heavy-duty coilers and uncoilers designed for continuous reversing mill operation. The powerful 800kW coiler motors provide excellent tension control across the entire rolling speed range. |
| Coil Handling | The complete line includes necessary coil handling equipment for efficient operation, though specific reel diameters and coil weight capacities would require confirmation from detailed specifications. | |
| 8. Support and Services | Spare Parts Availability | A list of spare parts to be delivered with the equipment is available (confirmation required). This will facilitate ongoing maintenance and minimize downtime after commissioning. |
| Disassembly Services | The supplier can provide professional disassembly services (cost to be confirmed), ensuring the mill is carefully dismantled, labeled, and prepared for transport. | |
| Refurbishment Services | Comprehensive equipment refurbishment and maintenance services are available (cost to be confirmed), allowing the buyer to upgrade and renew critical components before installation. | |
| Installation Support | As a full-solution provider, Keepwin Industry can offer technical support for installation and commissioning, ensuring a smooth transition to production at the new site. | |
| 9. Visual Documentation | Equipment Photos | The accompanying photographs (see original document) show the mill stand, control systems, and auxiliary equipment in their current condition, providing visual confirmation of the equipment's general state and maintenance level. |
| 10. Summary of Key Advantages | Modern Equipment | Manufactured in 2012, this mill is relatively modern with contemporary design features. |
| Precision 6-Hi Design | The 6-high roll configuration ensures excellent strip shape and thickness accuracy. | |
| Thin-Gauge Capability | Capable of rolling down to 0.15mm finished thickness. | |
| Powerful Drive System | Total of 4,000kW installed power across main and coiler drives. | |
| Proven Performance | Actual production data confirms design capabilities were achieved. | |
| Comprehensive Services | Full range of disassembly, refurbishment, and installation services available. |
