Can the double code magnetic encoder be used on hot rolling production lines?

The double code magnetic encoder is fully suitable for the hot rolling production line environment, and its design and functional characteristics can effectively cope with the harsh working conditions of this scenario. The specific advantages are as follows:

️️️1. Adaptability to harsh environments
The double code magnetic encoder adopts the principle of magnetic induction, without the need for optical components or mechanical contact, and the magnetic field signal is not affected by dust, water vapor, and high-temperature iron oxide scale interference. Its metal shell and fully enclosed structure (such as cast aluminum shell) provide physical protection, combined with IP67 protection level design, which can resist common dust, high temperature (≤ 1300 ℃ workpiece radiation) and coolant splashing in hot rolling production lines.

️2. Key position control application
Rolling mill main drive speed regulation: As a speed feedback component integrated into the main motor, it monitors the speed and direction in real time, and works with a fully digital speed regulation system (including voltage loop, current loop, and speed loop) to achieve high-precision roll synchronization control.
Roll positioning: directly measure the position and rotation angle of the roll to ensure the accuracy of steel plate thickness and width control, and avoid product size nonconformity caused by positional deviation.
Flying shear synchronization: used for detecting the speed and position of the flying shear machine, controlling the acceleration, uniform speed, and deceleration actions during the cutting process of steel billets, and ensuring the accuracy of fixed length cutting.
Pinch roller linkage: The lower pinch roller is driven to operate in coordination with the flying shear and rolling mill, maintaining speed matching at various stages of the production line and preventing steel stacking or breakage accidents.

️3. Fault tolerance and redundancy design
The double channel output signals are mutually backup. If a single channel experiences signal abnormalities due to strong electromagnetic interference or vibration, the system can automatically switch to the backup channel to avoid full line shutdown caused by encoder failure. This feature is crucial for hot rolling production lines that require extremely high continuity.

️4. Anti vibration and anti axis current design
Vibration reduction structure: Flexible couplings or insulated lining are used to connect the transmission shaft, absorbing high-frequency vibration impact of the rolling mill and reducing mechanical losses.
Shaft current protection: The insulation design blocks the shaft current generated by the harmonic of the frequency converter, avoiding the failure of the internal circuit of the encoder due to electrical corrosion.

5. Installation and maintenance advantages
Compact structure, can be directly embedded into equipment flanges or bearing positions, suitable for limited space scenarios in hot rolling production lines. Without vulnerable parts such as gears and gratings, it significantly reduces maintenance frequency caused by code wheel contamination or mechanical wear, and lowers downtime costs.
