The Electric Arc Furnace (EAF) is a widely used steelmaking solution designed to accommodate a flexible mix of raw materials—primarily scrap steel, but also molten iron, pig iron, sponge iron (DRI), and other iron-bearing materials. As a short-process steelmaking method, EAF offers low investment costs, minimal land occupation, and excellent environmental performance. With more than 40 years of industry experience, LIWEI has developed advanced AC three-phase EAFs incorporating modern technologies such as tunnel kiln scrap preheating (Consteel), secondary combustion, and flue gas heat recovery. These innovations reduce power consumption to as low as 360kWh per ton, while supporting high-quality steel production across a wide range of grades.
EAFs can process various iron sources including scrap, hot metal, and DRI, making them suitable for regions with diversified material supply. The process supports precise slag control, decarburization, alloying, and temperature management—enabling the production of specialty steels, such as stainless steel, tool steel, and heat-resistant alloys.
Our tunnel kiln scrap preheating system significantly cuts energy consumption by utilizing flue gas heat and secondary combustion to preheat scrap before it enters the furnace. This reduces electricity usage and accelerates melting time, contributing to lower operational costs and improved thermal efficiency.
The EAF steelmaking process is fully batch-based, allowing operators to switch between steel grades with minimal transition time. Auxiliary fuel injection (oil, coal, or natural gas) further enhances melting speed. All systems are designed for easy maintenance, quick electrode replacement, and efficient fume extraction.
| Parameter | Value |
|---|---|
| Furnace Type | AC 3-Phase Electric Arc Furnace |
| Power Consumption | As low as 360 kWh/ton (with Consteel) |
| Raw Material Compatibility | Scrap, DRI, Hot Metal, Pig Iron |
| Furnace Capacity Range | Customizable from small to large tonnage |
| Automation Options | HMI Monitoring, Auto Slag Control, Thermal Sensors |
| Energy Optimization | Scrap Preheating, Flue Gas Heat Recovery |
From basic carbon steels to high-performance alloys, the EAF allows for flexible and precise alloying, even with elements sensitive to oxidation like boron, vanadium, and rare earths. The ability to adjust composition mid-process makes it ideal for diversified production.
EAF does not rely on traditional blast furnace systems and generates lower emissions. Its compact layout and reduced auxiliary system requirements make it suitable for plants with limited space and budget-conscious operations.
LIWEI’s EAF technology has been successfully deployed in steel plants across Asia, Europe, and the Middle East. Our systems integrate advanced melting control, efficient material flow, and full-process support—from installation to technical training.
EAFs are the core of modern, scrap-recycling steel production. Their environmental efficiency and fast melting cycles make them ideal for circular economy steelworks.
Well-suited for manufacturing stainless steel, electrical steel, ball bearing steel, and other precision alloy products that require strict temperature and chemical control.
