F-EMS Solution
Final Electromagnetic stirring technologies are always used in combination with Mold EMS.
POSITIONING
Positioned in the mushy zone at the end of solidification.
FEATURES
Rotating stirrer (three-phase), low frequency and high power.
METALLURGICAL BENEFITS
- Redistribution of the solutes expelled from the solidification front and dilution by the less segregated liquid steel from the upper zones. Result is a more homogeneous content of carbon and alloy elements in the product cross section.
- Reduction of mushy zone temperature gradients. Result is a breakage or a significant delay in the formation of solidification bridges resulting in less trapping of segregated liquid.
- Feeding of new liquid to compensate for the volumetric shrinkage due to solidification – less porosity.
