An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc and the current in the furnace terminals passes through the charged material.
Arc furnace provides a simple and effective way of melting various grades of scrap and then going ahead to refine the metal to desired specification. It is also useful in making all kinds of steels including tool steels and alloy steels. This provides a method of utilizing low cost scrap, which is available in abundance. The key advantage in EAF melting is that refining is possible and you can also produce low carbon steels.

A typical 100t EBT furnace constructed by ZBTECH with mature design & stable quality, An electric arc furnace is mainly used for making steel and consist of devices like refractory-lined upper & lower shell, water-cooled roof, power cable, secondary circuit system, electrode raising & nippling system, roof raise & lower mechanism, lifting column, ladle, ladle car, water-cooling system, air compressed system, hydraulic system, lance system, H.V, L.V, auto control & computer system.
The tapping operation of the EBT electric arc furnace. When tapping, about 5° tilting to the tapping side, the tapping mechanism is opened, and the tapping filler automatically falls under the static pressure of the molten steel, and the molten steel flows into the ladle to realize automatic pouring and tapping. When the molten steel reaches about 95% of the required water, it will quickly recline to prevent the slag. In the back-dumping process, about 5% of the molten steel and a little slag will flow into the ladle. After the furnace is shaken, the steel is left in the furnace by 10% to 15%. Slag ≥95%) Inspection and maintenance of the steel tap, closing the taphole, adding filler, loading scrap, re-arcing smelting.
