Features of Steelmaking Electric Furnace
Simple equipment and small construction investment
The electric furnace system is relatively simple, with less civil engineering, which is convenient for rapid production and suitable for flexible plant construction and small and medium-sized layout. Among them, the induction furnace has advantages in equipment cost and operating manpower.
Strong ability to smelt high-alloy steel grades
The electric arc furnace can melt high-melting-point elements such as tungsten and molybdenum, which is suitable for the production of high-alloy steel and special steel; at the same time, it has good temperature control ability, and the terminal temperature control accuracy can reach ±5℃.
High thermal efficiency and strong adaptability
The arc temperature of the electric arc furnace is as high as 4000–6000℃, and the thermal efficiency is generally more than 65%. It is suitable for cold and hot charging of furnace materials, and even low-quality scrap steel (such as slag iron and large castings) can be used to smelt high-quality steel.
Possess strong refining capabilities
The electric furnace has excellent capabilities in deoxidation, desulfurization, degassing and alloying, especially the electric arc furnace. Combined with the LOD furnace and the LF refining furnace, the induction furnace can also construct the IF+LOD+LRF process to achieve a refining level similar to that of the electric arc furnace.
Charge. Scrap steel, sometimes mixed with DRI or HBI to improve chemistry, is loaded into the furnace shell.
Close and position. The roof is closed and the three graphite electrodes are lowered through the roof openings.
Arc and melt. Power is applied. An electric arc forms between the electrode tips and the charge and melts the scrap.
Refine. Oxygen, carbon, and fluxes (often lime) are injected to remove impurities and adjust steel chemistry.
Tap. When temperature and composition are on target, the furnace is tilted and liquid steel is poured into a ladle for further treatment or casting.
Slag removal. Non-metallic material is skimmed off separately.
Application of Electric Arc Furnace
Alloys production
Steelmaking electric furnaces are used to produce various alloys such as alloy steel, nickel, chromium, And others.
Recycling industry
These furnaces play a crucial role in the recycling industry by melting and reprocessing metal Scrap.
Production of specialty metals
Some valuable and specialized metals, such as titanium and vanadium, are also produced using steelmaking electric furnaces.
