Overview
ABB’s Tundish EMS provides gentle, global stirring of the entire tundish melt bath to eliminate dead zones, homogenize temperature and improve inclusion removal beyond what tundish furniture or conventional tundish stirring approaches can achieve. Designed for billet and bloom casting and metal powder production, it delivers longer sequences, lower superheat and more uniform strand performance – backed by 80+ years of electromagnetic stirring expertise and nearly 2000 EMS installations worldwide.
Cleaner steel through enhanced inclusion removal
<p>Global tundish stirring increases inclusion collision, aggregation and floatation, improving removal of smaller inclusions and clusters that conventional flow devices struggle to address.</p>Longer casting sequences with reduced nozzle clogging
<p>Cleaner steel and stable thermal conditions help reduce nozzle clogging, enabling longer casting campaigns and improved productivity. </p>More uniform temperature and chemistry across strands
<p>Whole‑bath homogenization reduces temperature and compositional variation between strands – a key challenge in multistrand billet and bloom casters.</p>Lower superheat and improved energy efficiency
<p>Optimized heat distribution supports reduced superheat, improving energy efficiency while maintaining stable and reliable casting conditions.</p>Reduced refractory and furniture consumption
<p>A more effective tundish flow field allows reduced reliance on dams, weirs and baffles, supporting lower refractory wear and consumable usage.</p>More repeatable casting conditions and product quality
<p>Stable flow and thermal behavior improve sequence‑to‑sequence repeatability, helping ensure predictable billet, bloom and powder quality.</p>FEATURES
Engineered to stir nearly the entire melt volume – eliminating dead zones and maximizing effective bath utilization
Stirring direction and strength can be tuned to caster layout, steel grade and process needs for precise metallurgical control.
Low melt‑surface velocity supports a calm slag layer and reduces slag entrapment while maintaining strong internal mixing.
Standardized installation configurations suit a wide range of tundish designs in billet and bloom casting and metal powder production.
Delivered with ABB converters, transformer and cooling modules – ensuring a unified and robust system architecture.
Advanced fluid‑flow simulation, RTD analysis and water‑model experiments validate stirring uniformity and flow‑field effectiveness.
External, non‑contact stirring equipment with no moving parts in the melt improves reliability, avoids mechanical wear and supports a long lifespan with minimal maintenance requirements.
ABB metallurgists provide guidance on tundish design, refractory interaction and flow‑field optimization.
Leveraging 80+ years of electromagnetic stirring expertise and nearly 2000 installations worldwide, ABB provides comprehensive commissioning, tuning and lifecycle support.
