OVERVIEW
ABB’s EMBR uses a static magnetic field to calm mold flow, sharply reduce mold powder entrapment and inclusion defects, and support higher casting speeds with slab cleanliness comparable to vertical bending casters. Installed on around 40% of all thin slab strands and backed by experience from 140+ slab mold installations, it delivers reliable quality, productivity and metallurgical expertise worldwide.
Key benefits
Reduces mold powder entrapments
<p>Lower meniscus turbulence cuts mold powder entrapments by up to 90%, delivering cleaner slabs and fewer inclusion‑related defects.</p>Improves coil surface quality
<p>A calmer, hotter meniscus reduces surface imperfections, enabling consistently higher‑quality coils even at increased casting speeds.</p>Enables higher casting speeds
<p>More stable mold flow supports higher throughput without sacrificing quality, boosting productivity for thin slab operations.</p>Extends mold lifetime
<p>Reduced level fluctuations lessen thermal cycling, lowering copper plate fatigue and helping many casters significantly extend mold life.</p>Raises steel temperature at the meniscus
<p>Lower turbulence keeps hotter steel near the surface, improving lubrication stability and reducing defect‑prone conditions.</p>Achieves cleanliness similar to vertical bending casters
<p>Controlled flow reduces inclusion penetration depth, enabling thin slab casters to reach cleanliness levels comparable to conventional slab casters.</p>FEATURES
A steady DC magnetic field controls liquid steel flow inside the mold, braking the SEN jets and helping maintain a uniform velocity profile across the strand.
EMBR is available for all thin slab caster mold designs - new installations and modernization projects - including compatibility with electromagnetic mold level control systems such as VUHZ.
Two‑ or four‑part coils on each mold wide face are fed by a dedicated thyristor converter, ensuring stable current delivery and reliable braking performance during thin slab casting.
With EMBR installed on around 40% of all thin slab strands worldwide and part of ABB’s portfolio of 140+ slab‑mold electromagnetic installations, customers benefit from decades of electromagnetic innovation and broad operational experience.
With no mechanical contact and robust coil construction using hollow copper conductors, internal water cooling, dry external insulation and protective silicon‑rubber casting, EMBR delivers durable performance with minimal maintenance requirements.
ABB Metallurgy provides in‑house metallurgists, electromagnetic stirring and braking specialists and a global lifecycle services organization offering commissioning, optimization, remote support and upgrades to maximize EMBR performance and ROI.
