TYPES OF STEEL MAKING FURNACES FOR SALE
EAF Electric Arc Furnace
Among types of steel making furnaces, EAF is mainly used for melting special steel from scrap, DRI, and HBI. Traditional EAF and CONSTEEL EAF compared with the other steel melting forge with higher temperatures up to 3000℃, easier temperature and liquid chemical control, more access to harmful element removal, and smaller investment. While, DC EAF, compared to AC EAF, lower electrode consumption up to 50% down, smaller melting power down by 5-10%, longer lining bricks life up to 30%,
 
Secondary Refining Furnace
Among types of furnaces in steel making, LRF is usually followed by EAF, IF for liquid steel further treatment, especially sulfur, inclusive slag reduction for cleaner liquid, as well as a buffer between the steel making furnace for steel and CCM. VD/VOD (Vacuum Oxygen Decarburization) considers the main melting of spring steel, prop steel, die steel, stainless steel, the removal of hydrogen and oxygen and nitrogen In liquid steel. ESR electric steel melting furnace, compared to EAF melting, with pure metal, dense organization, uniform composition, and smooth surface, results in longer service life and higher performance.
 
Submerged ARC Furnace
Among steel furnace types, CHNBZTECH SAF's main smelting varieties are ferromanganese alloy, industrial silicon metal, silicon manganese alloy, and low-carbon ferrochrome. From a small capacity of 3200KVA to up to 65000KVA, low carbon ferrochrome with chrome recovery ≥ 60%, Carbon ≤ 0.03 %. DC SAF compared to AC SAF, with 10% lower energy consumption, especially for power, and electrode paste. The Corundom(Al₂O₃) Furnace for steel melting can also melt white and brown corundum.
 
Furnace Auxiliary Equipment
CHNZBTECH operating an electric furnace steel mill provides induction furnace, CCM, rolling mill, WTF, and FTP to achieve final products like bloom, billet, rebar, coil, and slab. Among types of steel making furnaces, induction furnace is mainstream in foundry plants to produce castings, like flange, and auto parts. Continuous caster usually is designed and erected for billet, bloom, slab, and Auxiliary equipment like WTP, FTP, and power station around the main workshop to guarantee daily and normal running of the plant.
 
Furnace Auxiliary Spare Parts
Among types of furnaces in steel making, auxiliary Spare Parts is key and indispensable for the electric furnace steelmaking mill daily operation, different spare parts and consumable like EAF oxygen lance manipulator, LF roof, water-cooled power cable, scrap bucket, ladle preheater, copper busbar, electrode arm, copper mould, refractory and graphite electrode with different design, high quality can be provided for revamping or updating customer exist plant.

Electric Furnace Steel Making Process
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.
 
Steel Making Furnace Applications
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.
