AI Technical Summary

Technical Problem

In high-temperature environments, the hydraulic cylinder temperature of the electrode lifting device in a submerged arc furnace rises, causing the seals to fail and the distance between oil molecules to increase, resulting in air bubbles and posing a safety hazard.

Method used

A servo motor drives the worm gear and worm wheel mechanism, and the worm gear rotates synchronously through bevel gears and bevel gear rings, ensuring stable movement of the movable frame and avoiding malfunctions caused by excessive temperature of the hydraulic cylinder.

Benefits of technology

This improves the stability and safety of the electrode lifting device for electric arc furnaces, prevents hydraulic cylinders from malfunctioning due to high temperatures, and ensures the reliability of equipment operation.
