Precision Cold Mill for Ultra-Thin Carbon Steel Strips (Dismantled - Ready for Relocation)
1. Ultra-Thin Rolling Capability for Demanding Applications
This China MCC5 precision cold mill achieves exceptional thickness reduction capabilities, processing quality carbon steel strips from 5.0mm maximum entry thickness down to verified 0.11mm finished gauge. The precision cold mill maintains micron-level accuracy with ±0.002mm tolerance at 0.11mm thickness, making the China MCC5 precision cold mill suitable for producing precision shim stock, electronic component substrates, and specialized tool steel temper rolling materials. The precision cold mill's narrow-strip optimization accommodates widths from 100mm to 450mm, precisely matching requirements for high-value electronic component substrates production.
2. High-Speed Rolling Performance Parameters
The China MCC5 precision cold mill operates at industrial-scale throughput with maximum 300 m/min rolling speed. This rolling speed capability ensures efficient production of ultra-thin gauge materials while maintaining dimensional precision. The China MCC5 precision cold mill combines high rolling speed with exceptional thickness control through the integrated AGC (Automatic Gauge Control) system. This rolling speed and precision synergy positions the precision cold mill as an optimal solution for volume manufacturing of quality carbon steel strips requiring tight tolerances.
3. Advanced Roll Stack Configuration
Precision material reduction relies on the specialized roll stack within the China MCC5 precision cold mill:
Work Rolls: Ø120mm × 500mm body dimensions for direct material contact
Backup Rolls: Ø460mm × 460mm body providing foundational support
Intermediate Rolls: Ø190mm × 500mm body enhancing flatness control
The intermediate rolls represent a critical design feature of this precision cold mill, enabling superior strip flatness maintenance during high-reduction quality carbon steel processing. The geometry of the work rolls, backup rolls, and intermediate rolls collectively enables the China MCC5 precision cold mill to achieve stable 0.11mm output.
4. Siemens Control System Integration
The China MCC5 precision cold mill operates under comprehensive Siemens control system architecture. This Siemens control system integrates all critical functions including drive management, AGC operation, and process sequencing. The Siemens control system likely utilizes the SIMATIC TDC platform, providing deterministic control for the demanding ultra-thin gauge rolling processes. The Siemens control system interfaces directly with the mill's drive components to maintain precise synchronization throughout the rolling speed range.
5. Precision Measurement & AGC Technology
Thickness control incorporates two advanced subsystems:
Tsinghua thickness gauge providing non-contact strip profiling
AGC dynamically adjusting roll gaps in real-time
The Tsinghua thickness gauge delivers ±0.5μm measurement precision across the full strip width, feeding continuous data to the AGC system. The AGC processes this feedback to make microsecond adjustments to the roll positions, ensuring consistent quality carbon steel output thickness despite material variations. This measurement-control loop enables the precision cold mill to maintain 0.11mm gauge within ±0.002mm tolerance.
6. High-Power Drive System Configuration
Robust power delivery supports the precision cold mill's capabilities:
Main motor: 770kW power driving the reduction process
Recoiler motor: 355kW managing exit tension control
The main motor provides substantial torque for thickness reduction operations, while the recoiler motor ensures precise tension application during high-speed winding. The main motor and recoiler motor coordinate through the Siemens control system to maintain stability throughout the 300 m/min rolling speed range. This drive configuration enables the China MCC5 precision cold mill to process quality carbon steel efficiently from 5.0mm to 0.11mm.
7. Current Dismantled Status & Verification
The China MCC5 precision cold mill currently resides in dismantled condition at a Hebei facility, prepared for relocation. This dismantled status follows comprehensive structural integrity verification after decommissioning in 2023. The dismantled status includes careful component labeling, protective packaging of critical elements like the Tsinghua thickness gauge, and documentation of all disassembly stages. This dismantled status represents an opportunity for cost-effective acquisition of a proven precision cold mill with ultra-thin gauge capability.
8. Operational History & Technical Provenance
Originally commissioned in 2016, this China MCC5 precision cold mill accumulated approximately seven years of service in specialized quality carbon steel processing. The precision cold mill's technical pedigree combines:
China MCC5 mechanical engineering expertise
Siemens control system automation technology
Tsinghua University measurement science
This convergence of specialized technologies enabled the precision cold mill to achieve verified 0.11mm production capability for demanding applications including electronic component substrates and precision shim stock.
9. Relocation & Reintegration Advantages
Acquiring this dismantled precision cold mill offers significant benefits:
Immediate access to proven ultra-thin gauge technology
40-60% cost savings versus new equivalent mills
Avoidance of 12-18 month manufacturing lead times
Verified performance through operational history
