The furnace shell is composed of a furnace shell and a built-in refractory material.The overall framework of the furnace is conjoined, the furnace shell can be separated, a tube-type water-cooled furnace wall, a tube-type water-cooled roof, and eccentric bottom tapping. These industrial furnace spare parts consist of an upper furnace shell , lower shell, the EBT mechanism, and a tubular water-cooled wall.

The upper shell of the electric arc furnace is a cylindrical structure welded from steel pipes as a support, with a water-cooled furnace wall hanging inside and a water-cooled top cover installed in the eccentric area.
