Electromagnetic Stirring in Continuous Casting: Application and Value

Continuous casting is an important process in steel production. During casting, molten steel flows through the mould and solidification area before forming billets, round billets or slabs. The flow condition of molten steel can affect the internal structure and quality of the cast product.

Electromagnetic stirring, also known as EMS, is used in continuous casting lines to support molten steel movement through electromagnetic force. According to the product catalog of Shandong Luyue Electrical Co., Ltd., EMS products are available for billet casting, round billet casting and slab casting applications.

Common Applications of EMS

Billet continuous casting
Round billet continuous casting
Slab continuous casting
Steelmaking and metallurgical production lines
Molten steel flow control applications
Continuous casting process improvement

Typical EMS Positions in Continuous Casting

Mould EMS: Installed around or near the mould area to support molten steel flow during the early casting stage.
Final EMS: Used near the final solidification area of the casting process.
EMS for Round Billet: Applied in round billet continuous casting lines.
EMS for Slab: Used for slab casting applications according to production line requirements.
Travelling Wave Magnetic Field EMS: A product form shown in the catalog for slab casting applications.

Why Electromagnetic Stirring Is Used

In continuous casting, EMS can help promote molten steel movement in the casting section. Under suitable process conditions, electromagnetic stirring supports better flow distribution and helps improve metallurgical control during solidification.

The actual effect of EMS depends on multiple factors, including steel grade, casting section, casting speed, installation position, cooling conditions and production process requirements. Therefore, EMS selection should be based on the actual continuous casting line rather than a single standard model.

Key Factors for EMS Selection

Casting Type: Billet, round billet and slab casting lines may require different EMS structures.
Installation Position: Mould area, secondary cooling area and final solidification area have different requirements.
Casting Section: The size and shape of the cast product affect EMS selection.
Production Process: Steel grade, casting speed and process target should be considered.
Cooling System: EMS equipment often needs to work together with a cooling system.
Control System: Power supply and electrical control equipment should match the EMS configuration.

Supporting Metallurgical Production

Electromagnetic stirring is an important auxiliary technology for continuous casting production. It is not a standalone device only, but usually works together with power supply equipment, cooling systems and control systems.

For steel plants and metallurgical production lines, proper EMS selection can support process stability and metallurgical quality control. Before choosing an EMS system, users should confirm casting machine type, casting section, installation space, process requirements and cooling conditions.
