Tapping Spout EAF Furnace
Product Description
Tapping Spout EAF(Electric Arc Furnace)
Equipment composition: tilting mechanism, furnace shell assembly, water-cooled roof, roof lifting and swing device, electrode lifting device, high current system, cooling water system, hydraulic system, electrode extension station, electric furnace transformer, high voltage cabinet, low voltage electronic control system and so on.
Furnace features: The overall structure of the furnace adopts an elevated structure and a connected structure. The furnace roof is swung off & charging from top, the copper-steel composite conductive cross arm supply power , and the short spout for discharge slag, while long spout for tapping molten steel.

The electric arc furnace roof swung off and the electrode is arc-started. The whole process of smelting is about 90-250 minutes, depending on the size of the transformer, oxygen decarburization and phosphorus removal can be achieved in the melting down process, after the molten steel reach the temperature and composition required, liquid steel tapping out from the tapping spout with temperature around 1600-1700℃；
