It is widely used in electric arc furnaces and refining furnaces in the metallurgical field, and plays a conductive role in the smelting process. As an important auxiliary equipment for electrode extension, the degree of automation and operating efficiency of the electrode tilting device are of great significance to reducing the labor intensity of workers and improving production efficiency.
