Trustworthy Electric Arc Furnace (EAF) Manufacturer for Your Need

What is Electric Arc Furnace?
An EAF electric arc furnace china is a sophisticated industrial facility used for melting and refining various types of metals, primarily steel. The EAF furnace operates on the principle of electrical energy being converted into intense heat through an electric arc. In the furnace, an electric arc is generated between electrodes and the metal charge, resulting in temperatures exceeding 3,000 degrees Celsius. This extreme heat causes the metal scrap or raw materials within the electric arc furnace to melt. Types of electric arc furnace are widely employed in steel production due to their flexibility in handling diverse raw materials, including recycled steel. They offer advantages such as faster melting rates, precise temperature control, and reduced energy consumption compared to traditional methods, making the china electric arc furnace a pivotal technology in modern steelmaking processes.

The maintenance suggestion from the electric arc furnace EAF manufacturers in China

Reduction of the angle of tapping;

Simplify the tilting structure of the EAF furnace;

Reduce the copper busbar system impedance and increase life of the the electric arc furnace;

Retaining hot steel for slag operation;

No slag tapping, improves the quality of steel, is conducive to refining operations:

Hot heel & retain slag is conducive to EAF electric arc furnace treatment, and energy conservation;

Reduce the tapping temperature, save power consumption;

Reduce secondary oxidation and improve steel quality, increase ladle life of the steel making electric arc furnace.

TYPES OF ELECTRIC ARC FURNACE FOR SALE
EAF steel making usually can be divided into different category based on a different standard. Based on charging way, the electric arc furnace steelmaking can be divided into top charging EAF, horizontal and shaft continuous charging EAF. According to power supply, the electric arc steelmaking making can be divided into AC EAF, and DC EAF. Base on tapping direction, the EAF steelmaking can be divided into EBT and tapping spout.

Difference between electric arc furnace and induction furnace
A major difference between the compared electric arc furnace EAF melting process is the ability to use differing quality charge materials. Oxidation and reduction reactions take place within and above the melt zone during electric arc furnace steelmaking, which allows for the usage of highly oxidized and low-quality scrap material. Induction furnaces are more sensitive to low-quality charge materials and contaminants, resulting in premium scrap costs. A reductive atmosphere is not present and therefore iron oxide will not be reduced. This increases iron loss through the slag. Another charge material difference between the EAF melting process is the cost of alloys and nonmetallic additions. An induction furnace operation uses a high-grade silicon carbide to adjust iron chemistry. In addition, pure carbon in the form of graphite is used for carburization. These additions are costs not required for the EAF.
