Electric Furnace

Industrial Electric Furnace

for Steelmaking, Heat Treatment and Metal Processing

The Electric Furnace is a core thermal processing equipment widely used in steelmaking, casting, forging, rolling, and heat treatment industries. Compared with traditional fuel-fired furnaces, electric furnaces offer higher temperature control accuracy, cleaner production, improved energy efficiency, and better metallurgical quality.

Electric furnaces are suitable for melting, heating, refining, and heat treatment of carbon steel, alloy steel, stainless steel, non-ferrous metals, and special alloys. They are widely applied in steel plants, rolling mills, foundries, machinery manufacturing, and metallurgical engineering projects.

Main Applications

Electric furnaces are commonly used for:

• Steelmaking and secondary refining

• Billet and slab heating for rolling mills

• Heat treatment (annealing, quenching, tempering, normalizing)

• Alloy melting and refining

• Casting and forging heating processes

• Typical application fields include:

• Seamless tube and rolling mill production lines

• Section steel and bar production lines

• Foundries and metal casting plants

• Industrial heat treatment workshops

Types of Electric Furnace

According to application and structure, electric furnaces mainly include:

• Electric Arc Furnace (EAF)

• Induction Furnace

• Resistance Heating Furnace

• Ladle Furnace (LF)

• Electric Reheating Furnace

• Electric Heat Treatment Furnace

Each type can be customized according to production capacity, material type, and process requirements.

Key Advantages

• Precise Temperature Control
  Advanced electric heating and control systems ensure stable and uniform temperature, improving product quality.

• High Energy Efficiency
  Direct electric heating reduces energy loss and improves overall thermal efficiency.

• Clean and Environment-Friendly
  No direct combustion, low emissions, and easier compliance with environmental regulations.

• Flexible Operation
  Fast heating speed, quick start-up, and convenient automation control.

• Improved Metallurgical Quality
  Uniform heating minimizes oxidation, decarburization, and surface defects.

Working Principle

Electric furnaces use electrical energy converted into heat through arc heating, induction heating, or resistance heating. The generated heat is transferred to the metal charge in a controlled furnace chamber, ensuring uniform heating and stable thermal conditions throughout the process.

Modern electric furnaces are equipped with automatic control systems, enabling precise adjustment of temperature, power input, and heating curves.
