5 Applications Of Rotary Encoders In Rolling Mills

Rotary encoders play a major role in rolling mills as they provide position feedback, speed measurement of motor drives, torque monitoring, automatic gauge control, and screw down. To explain this further, Walker Machinery, a major distributor of digital encoders in Milton, Ontario, explores these 5 applications in detail.

What Are The Main Applications Of Rotary Encoders?

Position Feedback

Rollers play a major role in rolling mills. Position control of these rollers is critical for optimal functioning. Rotary encoders provide accurate feedback of the roller position to optimize operations.

Speed Measurement Of Motor Drives

For rolling mills, the speed of the motor drives needs to be constant to ensure the integrity of the end product. Shaft encoders also serve this application by providing the feedback of motor speed to the drive system. This helps monitor and maintain the speed of the motors in real-time.

Torque Monitoring

Although not a direct application, rotary encoders also provide some form of torque monitoring for rolling mills. This will help to detect any possible overloads of the motor and help prevent wear and tear on it.

Automatic Gauge Control

To ensure that the thickness of the end product is uniform, rolling mills require constant minor adjustment. Shaft encoders or rotary encoders help in this regard as well, as they can sense the roll positions.

Length Control

To ensure that the length of the material passing through the roller is also constant, rolling mills employ the use of rotary encoders. As they can measure the shaft rotation, it can be used to precisely cut the material to the right length. Therefore, it improves accuracy and throughput.
