Overview
With over 80 years of electromagnetic stirring expertise and more than 1000 billet and bloom stirrers installed worldwide, ABB offers the industry’s most comprehensive range of mold, strand and final stirrers. Tailored to your steel grades, section sizes and quality challenges, ABB’s solutions help reduce defect formation and support stable, reliable billet and bloom casting operations.
Improved solidification and internal structure
<p>Electromagnetic stirring supports more uniform structure formation during solidification, helping reduce internal billet and bloom defects.</p>Broad reduction of billet and bloom defects
<p>ABB’s MEMS, SEMS and FEMS address surface slags, subsurface slags, pinholes, blowholes, quarter‑band inclusions, interdendritic cracks, V‑segregations, centre porosities and centre‑line segregation.</p>Cleaner steel with fewer inclusion related imperfections
<p>Flow influence during solidification helps reduce inclusion‑driven imperfections that affect billet and bloom quality.</p>More stable casting behaviour for consistent quality
<p>Stabilized flow conditions across solidification zones support improved reproducibility and more predictable billet and bloom quality.</p>Calmer surface conditions with fewer slag related defects
<p>Electromagnetic stirring reduces disturbance‑related surface effects that contribute to surface and subsurface product defects.</p>Improved productivity and process efficiency
<p>With fewer defects and more stable casting conditions, ABB’s tailored stirring solutions contribute to higher productivity and reduced rejection ratio.</p>FEATURES
