Dc Steel-making electric arc Furnace
Application of equipment:
Used for melting ordinary steel, high quality carbon steel, alloy
steel, stainless steel.
Product overview:
Dc electric arc furnace is a type of electric arc furnace that uses
direct current as an energy source, mainly for melting steel or
alloys and non-ferrous metals. The working principle is to use the
arc generated between the electrode and the charge (or molten pool)
to generate heat, so as to achieve the purpose of melting.
Product features:
Compared with AC arc furnace, DC arc furnace has the advantages of
capital, equipment, environmental protection, especially operation
results, such as low electrode consumption, small voltage
fluctuation, and small impact on the power grid.
Product flow chart:
1. Loading: Transport the waste steel to the steelmaking workshop,
use a crane to lift the waste steel and put it into the steelmaking
furnace to fill the furnace;
2, melting: close the furnace cover, through the current, so that
the top graphite electrode and the bottom electrode produce a
strong arc, the high temperature of the arc makes the waste steel
quickly melt to form molten steel;
3, oxidation: oxygen is blown into the furnace, so that some
harmful elements in the molten steel (such as phosphorus, sulfur)
and oxygen chemical reaction to produce oxides, and with the slag
discharged out of the oven;
4, steel and refining: the refined molten steel is poured into the
ladle, and then further refining treatment, such as adjusting the
composition, temperature, etc., to meet specific quality
requirements.
