INVT's drive solution for bar and wire rod hot rolling production lines achieves full-link synchronization, micro-tension and high-performance control, adapting to the harsh working conditions of rolling lines and enabling efficient production.
Full-line Coordination: High-precision synchronous control is required for multi-zone rolling mills, which is prone to steel piling and drawing, directly resulting in scrap steel and production shutdowns.
Performance & Accuracy Requirements: Rolling mills demand extremely high dynamic response, which affects the dimensional accuracy and yield of bars and wires.
Harsh Operating Conditions: Severe on-site high temperature, dust and oil cause VFDs to overheat and age easily, leading to a high failure rate.
High Energy Consumption & Strong Impact: Strong acceleration and deceleration shocks, frequent heavy-duty starts and stops result in high energy consumption and great damage to the power grid and machinery.
Severe Impact of Faults: A single VFD failure will shut down the entire line, with slow troubleshooting and low operation and maintenance efficiency.
Communication Bus Requirements: Extremely high communication reliability is required; bus failures can cause steel piling accidents.
INVT takes the GD880 high-performance industrial VFD as the core, adopting a multi-drive architecture with a common DC bus for "rectifier + inverter".It integrates superior dynamic control, modular design for easy maintenance, rapid fault diagnosis, and high-reliability engineering, together with communication redundancy and safety functions.This makes it fully adaptable to on-site working conditions, ensuring efficient, stable operation and easy maintenance of the production line.
View Larger ImageExcellent Dynamic Performance: High-speed and high-precision loop control algorithms ensure outstanding dynamic response. Speed stability accuracy: ±0.01%, torque accuracy: ±3%, torque response time: <5 ms.
Easy Maintenance: Modular design of power units combined with quick-connect structure enables rapid replacement within 30 minutes.
Fast Fault Diagnosis: Faults are classified and graded. The fault black box supports data storage of 512 points across 10 channels within a specified time period, facilitating problem location
High Reliability: Long-life design of reliable components, enhanced three-proof coating process, and heavy overload capacity design.
Communication Redundancy: An all-in-one communication card supports adaptation to multiple protocols, dual-channel bus adaptation, and S2 ring network.
Safety Functions: Integrated STO (Safe Torque Off) function to build a higher-level safety architecture.
High-efficiency and superior control performance ensure high precision and stable operation, effectively boosting production efficiency, and enhancing dimensional accuracy and yield of bar and wire rod products.
The black box records faults for quick root cause location, and modules can be replaced rapidly, greatly shortening average fault processing time and accelerating production recovery.
Strict component selection standards minimize failures during the equipment life cycle, significantly cutting maintenance expenses.
Communication system redundancy is implemented to prevent full-line steel piling caused by single-point failures and improve network availability.
Higher safety level safeguards personnel and equipment, and avoids safety accidents.
