S-EMS Box Type
(External) Strand electromagnetic stirring technology.
POSITIONING
Linear inductor mounted in a “box” configuration behind the rollers of a slab caster segment.
FEATURES
Generates a strong horizontal, through-thickness AC magnetic field.
Requires segment modification and a manipulator for removal.
High electrical power demand.
Coils and a dedicated heat shield are cooled by demineralized water.
METALLURGICAL BENEFITS
- Enhanced internal structure: creates a powerful “butterfly” liquid flow, significantly increasing the equiaxed zone.
- Temperature homogenization: actively mixes hot and cold liquid steel regions for a more uniform internal structure during solidification.
- Defect elimination: stops ridging/roping in ferritic and silicon grades.
- Low maintenance: the heat shield is the only consumable part.
- Rapid ROI: quality improvements lead to payback in under one year.
