What is an Electric Arc Furnace?

Electric arc furnace (EAF) steelmaking utilizes electrical energy as the heat source, employing the intense heat generated by the electric arc between the electrode and the charge to heat and melt the charge.

This method is extensively employed in the production of various types of steel, including ordinary steel, high-quality carbon steel, a wide array of alloy steels, and stainless steel. Its broad range of applications makes it a pivotal piece of equipment in steel mills and foundries.

Technical Features:

• Water-cooled Furnace Wall and Cover: The furnace wall and cover are water-cooled to enhance durability and operational efficiency.
• Eccentric Bottom Tapping: This design facilitates easier and more controlled tapping of molten steel.
• Conductive Composite Cross Arm: This component ensures efficient transmission of electrical energy.
• Advanced Intelligent Electrode Lifting Regulator: This system optimizes energy usage, promoting energy conservation and reduced consumption.
• Industrial Configuration and Picture Monitoring System: These features provide comprehensive oversight and control over the steelmaking process.

Key Advantages:

1. Flexible Temperature Control: During the smelting process, the current and voltage can be precisely controlled to adjust the smelting temperature, catering to the specific requirements of different types of steel.
2. Simple Equipment and Short Process Flow: The EAF boasts a straightforward design and a streamlined process flow, contributing to high thermal efficiency.
3. Controlled Furnace Atmosphere: The atmosphere within the furnace can be regulated to optimize the smelting conditions.
4. High-Quality Steel Production: In alkaline EAF steelmaking, a significant amount of phosphorus, sulfur, oxygen, and other impurities can be removed from the steel, enhancing its quality. The alloy recovery rate is high and stable, the chemical composition of the steel is relatively easy to control, and a wide variety of steel types can be smelted.

The HX-type EBT (Eccentric Bottom Tapping) steel-making arc furnace, when paired with an LF (Ladle Furnace) for refining, is ideal for scrap remelting and the production of high-quality carbon steel, low-alloy steel, alloy structural steel, and various special alloy steels. The EBT electric arc furnace features a rotating furnace cover, eccentric bottom tapping, and a conjoined overhead installation structure.

The refining furnace section of the EAF is equipped with a conductive cross arm, tubular water-cooled furnace wall and cover, as well as advanced steelmaking equipment such as electrode electro-hydraulic proportional control and computer monitoring systems. The upper equipment is complemented by a high and low voltage power distribution system, an operating system, and a hydraulic system, ensuring complete, convenient, and straightforward operation.
