Industry Advantages of Frequency Converter Components

2024-08-16

The use of frequency converter components is becoming increasingly widespread in the metal processing industry. Various metal processing equipment, such as dual frequency converter wire drawing machines, in-line wire drawing machines, and steel plate rewinding machines, rely on frequency converter components to achieve efficient and precise operations. This article will explore the advantages of frequency converter components in metal processing and introduce specific application cases.

Application of Frequency Converter Components in Metal Processing Equipment

Frequency converter components have a wide range of applications in the metal processing industry. Here are some typical cases:

Dual Frequency Converter Wire Drawing Machine

This machine is primarily used to draw wire into fine threads of the desired specifications. The frequency converter components used in this equipment include the main drawing VFD and the take-up VFD. The main drawing VFD typically uses open-loop vector control, while the take-up VFD combines open-loop vector control with PID composite control. This combination ensures the stability and precision of the wire drawing process.

In-Line Wire Drawing Machine

The in-line wire drawing machine is used to gradually draw copper or steel wires and wind the finished product. The frequency converter components in this equipment control the motor's speed and torque to ensure uniform wire drawing. Unlike the dual frequency converter wire drawing machine, each drawing drum in the in-line wire drawing machine is driven by an independent motor, requiring the frequency converter components to precisely adjust each motor's operating state.

Stainless Steel Galvanizing Annealing Line Wire Drawing Machine

This equipment processes metal wires that have undergone pickling, heating, and galvanizing. The frequency converter components provide high-precision open-loop torque control in the traction wheels and coiling drums after the annealing furnace, ensuring a smooth transition when changing coils. This prevents impact and wire breakage during high-speed operation, ensuring the stability and efficiency of the production line.

Stainless Steel Plate Rewinder

In a steel strip annealing production line, the rewinder is responsible for rewinding the high-tension steel strip into the appropriate coil diameter. The key role of frequency converter components here is to ensure tension control and coil diameter adjustment during the rewinding process, thus improving production efficiency and ensuring the quality of the steel strip.

Industry Advantages of Frequency Converter Components

The application of frequency converter components in the metal processing industry offers several advantages:

Open-Loop Torque Control Without Speed Encoder Feedback

The open-loop torque control function of frequency converter components can widely replace traditional torque motors, eliminating the need for encoder maintenance. Advanced control technology allows frequency converter components to achieve precise torque control, reducing system complexity and maintenance costs.

Mature PID Control Algorithm

Frequency converter components use a mature PID control algorithm with strong adaptability. Multiple sets of PID gains and various PID limit options ensure fast adjustment and stable operation of the system, avoiding oscillations and enhancing the precision and stability of the processing process.

Superior Performance

Frequency converter components can achieve a speed precision of up to 0.02% and a torque output precision of 5%, with a response time of less than 10ms. These performance indicators ensure high precision in material processing and excellent synchronization, meeting the strict requirements for precision and efficiency in the metal processing industry.

Comprehensive Control Solutions

Frequency converter components offer various control solutions, adaptable to both rod and rodless scenarios. This flexibility makes frequency converter components perform excellently in different metal processing applications, meeting diverse needs.

Compatible Power Specifications

Frequency converter components support 220V and 380V power inputs, increasing their applicability in various industrial environments. This design allows frequency converter components to be widely used in various metal processing equipment, enhancing the equipment's compatibility and flexibility.
