Steel production is a crucial industry that plays a significant role in various sectors, including construction, automotive, and manufacturing. Electric Arc Furnaces (EAFs) are a vital component of steelmaking processes, allowing for the efficient melting and refining of scrap steel. One essential e
READ MORECompoundsMost silicon is used industrially without purification and, in fact, is usually relatively little processed from its native form. More than 90 percent of the Earth's crust is made up of silicate minerals, which are compounds of silicon and oxygen that often carry metal ions while negatively
READ MOREVacuum arc remeltingVacuum arc remelting (VAR) is a secondary melting process used to produce metal ingots with increased chemical and mechanical homogeneity for demanding applications. [1] The VAR process has revolutionized specialized traditional metallurgical technology indust
READ MOREProducing one ton of steel in an electric arc furnace requires about 400 kWh per short ton (1.44 gigajoules) or about 440 kWh per ton (1.6 GJ); the theoretical minimum energy required to melt one ton of scrap is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)). Thus, a 300-ton, 300-MVA EAF woul
READ MOREAn Electric Arc Furnace (EAF) is a furnace in which materials are heated by an electric arc.Industrial electric arc furnaces range in size from small units with a capacity of about 1 ton (used in foundries for the production of cast iron products) to about 400 ton units for secondary steelmaking. E
READ MOREWhen the electric furnace is tapped, the furnace body is inclined to the tapping direction at a certain angle (usually 45s), and the molten steel flows through the tapping trough and enters the ladle. In addition to diversion of the molten steel, the tapping trough also prevents the molten steel from dispersing and protects the molten steel from secondary oxidation.
READ MOREThe oxidation period of ordinary power electric arc furnace steelmaking usually refers to the process stage from the dissolution of the charge, sampling and analysis to the completion of the oxidation slag. Some think it started from blowing oxygen or adding ore to decarbonize.
READ MORETo achieve slag-free tapping of electric furnaces, traditional tapping methods need to be changed. The rapid progress of electric furnace technology is not only reflected in the number of electric furnaces, but also the furnace type and tapping mechanism and control methods are constantly changing and updated, making the electric furnace slag-free tapping technology more perfect and diversified.
