Electric arc furnace refers to the high temperature produced by the electrode arc smelting ore and metal electric furnace. The energy is concentrated when the gas discharge forms an arc, and the temperature of the arc zone is above 3000 ℃.

Refining furnace is a kind of smelting equipment commonly used in the thermal processing industry, and is mostly used in the final deoxidation and alloying process of molten steel in ferrous metallurgy.

The ladle furnace is an out-of-furnace refining technology using arc heating under vacuum conditions. The ladle furnace is one of the main equipment for refining the molten steel in the general steelmaking furnace in a special ladle.

The rolling mill is the place where the production of rolled steel is carried out. Steel rolling production is the production process of rolling ingots or billets into steel.
