The electric arc furnace is mainly composed of electrode holder, electrode, furnace cover, molten bath, furnace door, tilting cradle, hydraulic steel and other components. The furnace bottom and furnace wall are constructed of acidic or alkaline refractory materials. First, the electric energy is transmitted to the furnace through the electrode, and then the electrode and furnace charge are used to generate electric arc to raise the temperature in the furnace. Finally, the high temperature makes the ore metal melt.

A tapping box protruding from the furnace shell is installed on the original tapping side to replace the original tapping groove. Refractory materials are built inside the tapping box, and a small molten pool is formed. It is connected with the large molten pool at the bottom of the original furnace and has a smooth transition. The tapping hole is opened vertically at the bottom of the small molten pool of the tapping box.

In the early days, the direction of rotation of the closing mechanism of the tap hole of DEMAC was vertical, and later it was mostly changed to the horizontal direction. For example, the BSE tapping technology in Germany, its advantage is that the plate that closes the tap hole moves horizontally, and the total height is low.
