The line speed of the transmission device of the fully automatic
continuous galvanizing line is precisely controlled by a high-precision speed control system to keep it consistent. It uses the S71500 inverter to adjust the motor speed of the driving transmission roller, uses the coil diameter calculation function, and uses the line speed or encoder signal to dynamically adjust the torque. It ensures the smooth transportation of the strip and solves the problems of speed difference, strip stretching, and wrinkling.
The strip tension in each tension zone of the
galvanizing production line is carefully balanced and stably controlled, which can control the strip tension in the heating furnace, and is installed with a tension control device and integrated tension closed-loop control. Our
hot dip galvanizing line's electronic control system has PLC control, transmission control, temperature control, and HMI human-machine interface. It can automatically adjust the braking force or motor speed of the relevant roller shaft to maintain tension and reduce manual deviation. It can control the unwinding and winding tension of the strip to avoid slipping or breaking.
