ELECTROMAGNETIC STIRRER SYSTEMS

M-EMS, S-EMS AND F-EMS FOR BILLET AND BLOOM CASTERS

Electromagnetic stirring (EMS) improves quality and productivity in continuous casting. The rotating field induces magnetodynamic forces in the liquid steel producing rotational flow, thereby providing better heat transfer and gas release, improved equiaxed zone, and minimizing carbon segregation, inclusions, porosity, surface and internal cracks.

Ergolines offers Mould-, Strand- & Final-EMS coils, with wet- or dry-insulation technology; internal and external M-EMS design.
Systems can also include: special cables, junction boxes, complete VVVF Inverter stations, transformers, cooling water systems, Gauss-meters, spare parts.
A typical project package includes:

  • Analysis of metallurgical process requirements;
  • Computer aided coil calculation & design and magnetohydrodynamic analysis;
  • Optimization of operating parameters (current, voltage, frequency, position);
  • Magnetic, electric, hydraulic and mechanical design + production engineering;
  • Manufacturing and testing;
  • Start-up and commissioning;
  • After-sales service.
