AI Technical Summary

Technical Problem

In existing strip steel finishing lines, motor selection relies on manual experience, which is inaccurate and time-consuming, and cannot meet the requirements of tension distribution and motor selection for strip steel of different materials.

Method used

By calculating the width, thickness, and yield strength limit of the strip, the tension requirement at the entrance of the straightener is determined, and the tension requirement at each tension roller is gradually derived. Combined with the basic parameters and output torque of the motor, the motor is selected to meet production needs.

Benefits of technology

It enables precise tension distribution calculation and motor selection, improves production efficiency, optimizes strip processing quality, enhances adaptability and flexibility, and ensures that the motor meets tension requirements at different speeds.
