Technical Definition

An Electric Arc Furnace (EAF) steel smelting plant is a short-process metallurgical production system that uses electric arc heat to melt scrap steel, direct reduced iron (DRI), or pig iron into qualified molten steel, based on the underlying principles of arc heating and precise composition regulation. It enables low-energy, low-emission steel production, and has become a core technical support for global steel industry low-carbon transformation.

To meet diverse industrial and operational requirements, our EAF systems cover two mainstream series, with customizable solutions for special scenarios:
1. Top-charging EAF series: Positioned for standard carbon steel production, suitable for regions with abundant scrap steel resources, with core features of low upfront investment and short construction cycles.
2. Horizontal continuous charging EAF (Consteel) series: Positioned for high-DRI smelting and alloy steel production, suitable for regions with strict environmental requirements, with core features of low energy consumption and high arc stability.

Our EAF systems are designed with the core philosophy of high reliability, customizability, easy integration, and optimal full-lifecycle cost, fully considering the harsh operating conditions of industrial scenarios and strictly following full-lifecycle reliability design standards.

Technical Principle

The core working principle of our EAF steel smelting plant is to generate high-temperature heat through electrodes to melt solid raw materials into molten steel, while regulating slag composition to achieve dephosphorization, desulfurization, and other refining operations. The complete implementation logic is as follows:
1. Raw material input: Raw materials (scrap, DRI, pig iron) are fed into the furnace via top charging or continuous charging systems, based on pre-defined proportion requirements.
2. Heat input: The electric arc generated by electrodes raises the furnace temperature to over 1600°C, completing the melting of solid raw materials.
3. Composition regulation: Alloys are added and slag composition is adjusted to precisely control the chemical composition and purity of the molten steel.
4. Molten steel output: Qualified molten steel is poured into ladles and transported to the continuous casting process.

Core architectural innovations include:
1. Continuous feeding system module: Adapted for high-proportion cold or hot DRI smelting, improving smelting efficiency by over 25% compared to traditional top-charging systems.
2. Ultra-high power transformer module: Ensures arc stability during continuous feeding, reducing unit steel power consumption by 10% compared to industry average levels.

Compared to traditional blast furnace-converter long-process routes, our EAF solution delivers two core breakthroughs:
1. Carbon emission reduction: Unit steel CO₂ emissions are only 0.4-0.6 tons, 70% lower than long-process routes, meeting global environmental compliance requirements.
2. Cost and cycle reduction: Upfront investment is only 1/2 to 1/4 of long-process routes, with construction cycles shortened by over 60%.

Technical Parameters and Specifications
