CHNZBTECH specializing in the electric furnace for steel manufacturing covers design, engineering, supply, and commissioning for whole short-line steelmaking furnaces, from EAF, Secondary refining furnaces, VOD to CCM, rolling mill, as well as spare parts. EAF is divided into DC EAF, CONSTEEL EAF, and traditional top-charging EAF, meanwhile, Secondary refining furnaces including LF, ESR, and AOD, are within supply scope as well.
CCM usually are the main facility for casting liquid, based on the form of shapes, common see billet caster, bloom caster, and slab caster. Additional, CHNZBTECH, as one of the leading steel furnace manufacturers in China, providing ferroalloy melting and steel melting equipment solutions, main smelting varieties are silicon manganese alloy, industrial silicon, and ferrosilicon alloy, low micro carbon ferrochrome.

CHNZBTECH: Base on different melts and heats method, usually types of steel making furnaces can be divided into induction furnaces, AC arc furnace, DC arc furnace, Submerged arc furnaces. Consider refining function, CHNZBTECH, one of the professional steel furnace manufacturers, also offers LF, VD/VOD furnace, ESR furnace.
CHNZBTECH: Different capacity of furnaces configured with different transformer, tap to tap from 120minuts to 35minutes. Larger capacity EAF, are powered also by oxygen lance manipulator from furnace door, ET lance from side-wall which decrease melt down time. Scrap continuous feeding and preheating enables EAF with CONSTEEL tap liquid within 35minutes, and power consumption lower to 290 KW.H/t.
CHNZBTECH: it depends on site condition of exists steel melting furnace. Usually only EAF roof, copper busbar, water cooled welding cable, electrode arm, clamping rings, vacuum circuit breaker, those vulnerable and quick-wear parts need to be replaced after due time of working. Revamping and updating steelmaking furnaces are also potential ways for morden steel plants.
CHNZBTECH: air melting furnace usually are considered as normal type furnace like EAF, SAF, IF. Which electrodes exposed to air and melting down at relative open atmosphere. However, consider vacuum melting furnace usually refers to VD/VOD, VIM, VAR, those machines are equipped with vacuum suction pumps, which remove nitrogen, hydrogen, oxygen, under vacuum.
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.
