Galvanizing Line Control & Management System WEDONE

Integrated PLC Automation, Process Monitoring and Production Data Management

The WEDONE Control & Management System integrates equipment control, process monitoring and production data management for hot-dip galvanizing lines. Based on Siemens PLC technology, the system provides operators with centralized visibility and control from pretreatment through galvanizing.

• Siemens S7-1200 or S7-1500 PLC control platform
• Centralized monitoring of equipment and production status
• Integration with cranes, RGV systems and pretreatment equipment
• Monitoring of tank level, temperature, concentration and other process parameters
• Production data collection, historical records and traceability
• Alarm display and fault-diagnosis functions
• Multi-level user authorization for data and operational security
• Optional remote supervision, diagnosis and technical support
• Customized interface and control logic for each production line

By improving process visibility and equipment coordination, the system helps operators maintain stable production, respond to faults efficiently and support consistent galvanizing quality.

Working Principle

The Control & Management System uses advanced sensors, programmable logic controllers (PLC), and human-machine interfaces (HMI) to monitor and control key parameters such as temperature, bath composition, line speed, and zinc coating thickness. It provides operators with real-time data, enabling immediate adjustments and efficient management of the galvanizing process.

Application in Hot-Dip Galvanizing

The Control & Management System is essential for hot-dip galvanizing lines, providing centralized control and monitoring of key production parameters. By automating the process and optimizing the use of energy and resources, it helps ensure consistent product quality, improve operational efficiency, and reduce waste, leading to a more sustainable galvanizing operation.

Frequently Asked Questions

Which equipment can be integrated into the control system?

The system can coordinate galvanizing furnaces, automatic cranes, RGV material-handling systems, pretreatment tanks, pumps, dryers, environmental equipment and other production-line devices. The integration scope is customized for each project.

What process parameters can the system monitor?

Depending on the installed instruments, the system can monitor tank levels, temperatures, solution concentration, density, metal-ion concentration, equipment status, production cycles and alarm conditions.

Does the system support production-data storage and traceability?

Yes. Operating data, alarms and production records can be collected and stored for historical review and process analysis. The exact data structure and retention period are configured according to project requirements.

Can WEDONE provide remote diagnosis and technical support?

Yes. An optional IoT-based remote service function can allow authorized WEDONE engineers to review operating status and assist with troubleshooting. Remote access is protected through controlled authorization and agreed security settings.

Can the system upgrade an existing galvanizing line?

Yes. WEDONE can assess the existing PLCs, instruments, electrical cabinets, equipment interfaces and communication network before developing a retrofit solution. Compatibility depends on the age and condition of the installed equipment.
