DCS Solutions for Turnkey Paper Production Lines
Modern paper production demands sophisticated automation control to achieve consistent quality, minimal downtime, and optimal energy efficiency. As a turnkey paper mill machinery supplier, Leizhan provides complete automation control solutions that integrate Distributed Control Systems, Quality Control Systems, and Motor Control Centers into a unified platform for seamless operation across your entire paper manufacturing line.
Our automation control scope covers everything from pulping and stock preparation to the paper machine, rewinder, and auxiliary systems, ensuring every process stage operates with precision. The automation control system is built on Siemens PCS7 technology, a world-class process control platform that delivers high reliability, powerful functionality, and excellent scalability. With a system availability rate exceeding 99.9 percent, our automation control ensures uninterrupted production and rapid response to process variations. From high-voltage feeds through MCCs to MCS, DCS, and QCS, Leizhan’s automation control provides full responsibility for system design, engineering, and integration across the entire mill.
Our automation control solutions are designed to meet the demanding requirements of modern paper mills, covering all critical control functions. The DCS (Distributed Control System) forms the backbone of our automation control, handling data acquisition, PID loop control, sequential control, and interlock protection across the entire paper making line. The automation control system includes high-performance controllers with substantial processing power, ensuring that all control algorithms run efficiently even in large-scale installations. For a typical paper mill project, our automation control configuration includes multiple I/O stations with analog inputs, analog outputs, digital inputs, and digital outputs, all carefully sized with built-in expansion capacity. The automation control system incorporates Siemens ET200SP distributed I/O stations with push-in terminals for easy wiring, modular design for flexible configuration, and hot-swap capability for maintenance without production interruption.
Our automation control also integrates MCC systems that provide variable frequency drive control for critical paper machine components, enabling smooth acceleration, deceleration, and precise speed regulation. The MCC portion of our automation control includes motor starters, VFDs, and protective devices, all coordinated through the DCS for intelligent motor management. Additionally, our automation control integrates QCS (Quality Control System) for real-time measurement and control of basis weight and moisture, using high-precision sensors with automatic compensation and self-cleaning features. Communication between all components of the automation control system is via Industrial Ethernet and PROFIBUS fieldbus, ensuring high-speed, reliable data exchange. The automation control also supports open communication protocols including OPC and TCP/IP for seamless integration with third-party systems such as drives, MCS, and enterprise networks.
Leizhan is your single-source partner for complete paper mill automation control, delivering integrated DCS, QCS, MCC, and drive solutions as part of our turnkey paper production lines. Our automation control engineering covers system design, hardware configuration, software programming, installation supervision, commissioning, and operator training.
