S-EMS in Roll
(Integrated) Strand electromagnetic stirring technology.
POSITIONING
Integrated directly into existing roll segments within the strand,
in either face-to-face or side-by-side configurations.
FEATURES
Produces a horizontal AC magnetic field using linear motor technology.
Designed for minimal footprint and optimized power consumption
(≈120 kVA per pair), cooled by water.
METALLURGICAL BENEFITS
- Enhanced internal structure: promotes equiaxed grain formation, significantly reducing center porosity and segregation.
- Defect elimination: stops ridging/roping in ferritic stainless and silicon steels, and reduces crack susceptibility in carbon grades.
- Process flexibility: offers single-stage for low superheat casting and double-stage for higher superheat for superior thermal homogenization.
- Tailored flow control: generates a “butterfly” stirring pattern (single-stage) or a “triple zero” stirring pattern (double-stage) to actively mix hot liquid steel with colder liquid steel.
- Easy integration & roi: minimal impact on caster mechanics, lower maintenance, and rapid payback (under one year) through quality gains.
