An electric arc furnace is an industrial device that uses the high temperatures generated by electric arcs to heat and melt materials, playing an important role in modern industrial production. Its working principle is based on the phenomenon of electric arc discharge. When a high voltage difference is formed between the electrode and the material, the air is ionized, creating a conductive plasma channel, which is the electric arc. The temperature of the electric arc is extremely high, reaching several thousand degrees Celsius, allowing materials to be quickly melted or undergo high-temperature reactions.
Using large forging equipment, the heated steel billets undergo multiple operations such as upsetting and elongation, which densifies and homogenizes the internal structure of the metal, eliminates original defects, and forms the basic outline of the wheel. During the forging process, temperature, pressure, and deformation are precisely controlled to ensure the Size accuracy and internal quality of the wheel.
