Advantages of Electric Arc Furnace Bottom Blowing Technology


What is the bottom blowing technology of the electric arc furnace? 

What are the advantages? 

With the expanding market and increasing demand, the bottom-blowing technology of electric arc furnaces comes into being. Many steel mills have introduced the bottom blowing technology of electric arc furnaces successively, because this technology can greatly shorten the smelting time, reduce the content of iron oxide in slag and improve the yield of metal, thus achieving a function of reducing the consumption of ferroalloys. Low arc furnace blowing technology can also uniform the composition and temperature of molten steel, so it is recognized by everyone!

The arc furnace bottom blowing technology has some points which can be roughly summarized as follows:

1: EAF bottom blowing technology reduces the soft melting in the cold zone, promotes the melting of waste steel, and plays an active role in eliminating the cold zone in EAF steelmaking.

2: EAF bottom blowing technology improves the reaction speed at the steel slag interface, promotes the adsorption and removal of impurities in EAF rough steelmaking, improves the reaction speed of dephosphorization and decarbonization, and plays an active role in shortening the smelting cycle.

3: Bottom blowing technology of electric arc furnace accelerates the running speed of molten steel in the molten pool and plays an important role in eliminating the phenomenon of uneven temperature in the molten pool. The key point is that the temperature of steel discharging can also be reduced.

4: Due to one stirring effect of bottom blowing, the reaction at the steel slag interface is particularly balanced, and the iron oxide content in the slag is greatly reduced, which is conducive to the reduction of iron consumption.

5: The bottom blowing technology of the electric arc furnace reduces the tapping temperature and iron oxide content of the electric arc furnace, so the life of the lining is also prolonged.
