The types of electric arc furnace (EAF) operates by using electric energy to create a high-intensity electric arc between two or more graphite electrodes and the scrap metal inside the steelmaking furnace. The electrodes are lowered into the furnace and positioned above the scrap metal.
As the electric current passes through the electrodes, it creates an arc that generates intense heat, reaching temperatures of around 3000 degrees Celsius (5400 degrees Fahrenheit). This heat through the electric furnace steel making process causes the scrap metal to melt and form a pool of molten metal in the bottom of the electric steel melting furnace.
The heat from the electric arc also helps to remove impurities and oxidize any unwanted elements in the scrap metal. These impurities rise to the surface of the molten metal and are removed through slagging, where a layer of fluxing agents is added to this steel melting furnace to absorb the impurities and create a slag layer that floats on top of the molten metal.
Small casting with high quality melting. The steelmaking furnace can not only be used in casting factories for flexible casting of small parts, but also in the mechanical processing industry.
Steel billets, deformed steel, and steel balls melting. Small MINI steel plants are used to produce steel billets, deformed steel, and steel balls. In recent years, due to the development of the steel ball market, more types of steel making furnaces have been used to produce molten iron, using high-speed centrifuges machines and various heat treatment equipment to produce steel balls of different sizes. Compared to medium frequency steelmaking, electric furnace steel can better control harmful components to molten steel, and raw materials have more selectivity.
Polysilicon, monocrystalline silicon, and organic silicon melting. Similarly, the submerged electric arc furnace is also an important part of steelmaking and ferroalloy production. Currently, with the development of the global spectroscopic industry, there is a greater and deeper demand for industrial silicon in the market. These metallic silicon are melted in submerged arc furnaces and further processed to produce polysilicon, monocrystalline silicon, and organic silicon.
Special steel like ball steel, bearing steel, tool steel melting. Enhanced by different refining facilities like LF furnace, VD VOD furnace, RH, ESR, VAR, VIM, primary molten steel could be easily treatment with any specially chemical analysis, like ultra low carbon, sulfur, phosphorus, but with high content of benefits elements like manganese, chrome.
