4-Hi 950mm Cold Rolling Mill

    This is a used 4-Hi reversible cold rolling mill manufactured in 2012, capable of rolling down to 0.18mm in practice, equipped with Siemens electrical control and AGC system, and comes with abundant spare parts including 32 new work rolls.
    No.Highlight CategoryDetailed Description
    1Wider Rolling WidthThe designed maximum rolling width is 850mm, and the actual rolling width achieved by the previous owner reached 910mm, exceeding the design value. This width is suitable for high-volume production of wide stainless steel strips, meeting the stringent width requirements of industries such as kitchenware, hardware stamping, architectural decoration, and automotive components.
    2Thinner Finished ThicknessThe designed minimum finished thickness is 0.2mm (design limit up to 0.02mm), and the actual minimum thickness achieved by the previous owner is 0.18mm, better than the design specification. This precision is suitable for ultra-thin stainless steel strip production, widely used in high-tech, high-value-added fields such as electronic components, precision medical devices, new energy battery casings, and flexible display backplanes.
    3Larger Input Thickness CapacityThe designed maximum input thickness is 3mm, and the actual input thickness achieved by the previous owner is also 3mm. This wider input range allows the equipment to handle thicker hot-rolled stainless steel coils, reducing pre-rolling processes and improving overall line efficiency.
    4Higher Power Main Motor SystemThe main motor is model Z710-3 with a power rating of 1050kW and a speed range of 330-1000 rpm. This represents a 40% power increase compared to 750mm-class equipment (750kW). Higher power means stronger rolling capacity, larger reduction per pass, and higher production efficiency.
    5Dual-Motor Coiling ConfigurationThe recoiler is equipped with two 450kW motors (total 900kW) with a speed range of 400-1200 rpm, and the uncoiler is similarly equipped with high-power motors. The dual-motor coiling design provides higher coiling tension, smoother acceleration/deceleration control, and better tension distribution uniformity.
    6Higher Rolling SpeedThe rolling speed reaches 300 m/min, a 50% increase compared to 750mm-class equipment (200 m/min). Higher speed means higher output per unit time, delivering significant economic benefits for continuous rolling production modes.
    7Higher Rolling ForceThe maximum rolling force is 1000 tons, far exceeding the capability of 750mm-class equipment. This enables the equipment to handle harder materials (such as 304, 301, and other high-strength stainless steels), achieving larger reduction per pass and reducing the number of rolling passes required.
    8Optimized Roll SpecificationsThe working roller size is Φ180×980mm, and the backup roller size is Φ725×950mm. Compared to 750mm-class equipment, the larger working roller diameter provides greater rigidity and strength to withstand 1000 tons of rolling force without excessive elastic deformation.
    9AGC Hydraulic Screw-Down SystemThe equipment uses an AGC (Automatic Gauge Control) hydraulic screw-down system, offering core advantages over electric screw-down: millisecond-level response speed, micron-level control accuracy, dynamic compensation for rolling force fluctuations and roll thermal expansion, and consistent thickness along the entire strip length.
    10Siemens Electric Control SystemThe electric control system is manufactured by Siemens, a global leader in industrial automation. Siemens control systems feature high stability, strong anti-interference capability, user-friendly programming environment, abundant spare parts supply, and well-established technical support networks.
    11Extensive Spare Parts InventoryThe spare parts list is exceptionally rich: 64 work rolls (including 32 brand new ones), and 5 backup rolls (2 with chocks, 3 without chocks). This massive spare parts inventory means the buyer will not need to purchase additional rolls for many years, significantly reducing operating costs and downtime risks.
    12Relatively New Manufacturing YearThe equipment was manufactured in 2012, two years newer than the previous equipment (2010). A newer manufacturing year means more modern design, less aging of electrical components, less mechanical wear, and longer remaining service life. The equipment was taken out of service in March 2026, less than 3 months ago, maintaining good condition.
    13Solid Drum Coiling MechanismThe coiling method uses a solid drum, which is simple and durable. Compared to collapsible drums, the solid drum has a lower failure rate and lower maintenance costs. The solid drum offers good rigidity, resisting deformation during high-tension coiling, helping maintain neat coil shapes.
    14Strong Material AdaptabilityThe designed rolling material is SS (stainless steel), covering multiple grades such as 201, 304, and 301. Compared to equipment specifically designed for SUS 201, this equipment has a wider material adaptability range, flexibly handling stainless steel strips of different materials, hardness levels, and processing characteristics.
    15Performance Fully Verified by Actual Rolling DataActual production data from the previous owner: maximum width 910mm (exceeding design value), maximum input thickness 3mm, minimum finished thickness 0.18mm (better than design value), rolling speed 300 m/min. All core parameters have been verified in actual production, ensuring reliable equipment performance.
    16Disassembly and Refurbishment Services AvailableThe supplier offers disassembly, refurbishment, and maintenance services (costs to be confirmed separately). Disassembly services include complete machine disassembly, component labeling, rust-preventive packaging, and loading for shipment. Refurbishment services include roll grinding, bearing inspection and replacement, seal replacement, hydraulic system cleaning, electrical system testing, and frame cleaning and painting.
    17Reliable Equipment Source with Clear HistoryThe equipment manufacturer information is complete, with manufacturing in 2012 and decommissioning in March 2026. The equipment has operated stably for over 14 years. The reason for decommissioning is plant production line upgrades, not equipment failure, so the core components remain in good condition.
    18High Cost-Effective Used Equipment ChoiceCompared to new equipment of the same specifications (typically 10-18 months delivery, high price), this equipment significantly shortens the procurement cycle (can be shipped within weeks) and reduces initial investment costs (typically 20-40% of new equipment price). Combined with the extensive spare parts inventory and optional refurbishment services, this equipment is a highly cost-effective choice for quickly starting stainless steel cold rolling projects.
