ABB will be presenting Tundish EMS, a new electromagnetic stirrer for superior temperature control in the tundish at METEC 2023

Frederik Esterhuizen, Global Business Line Manager, and Bernd Sachweh, Cluster Manager Europe, from worldwide leading technology group and expert partner for the metals industry, ABB will be at METEC (Hall 4/Booth D21) showcasing safer and smarter solutions and innovative products and services for more efficient operations across the metals industry.

With over 100 years of experience in the metals industry, ABB’s complete range of products, services and end-to-end solutions improves productivity, quality, safety and cost-efficiency in iron, steel and aluminium manufacturing. ABB partners with metals companies at every step of the process from yard to market, whether that be iron or steelmaking, hot rolling, cold rolling or processing lines.  

ABB recently launched ABB Tundish EMS, a new technology solution for billet, bloom casting and metal powder production that enables accurate, homogenous, stable control of steel temperature in the tundish.

This tundish-focused electromagnetic stirring solution helps steelmakers increase quality, productivity and profitability in billet and bloom casting and metal powder production. The new technology enables steel plant operators to overcome challenges of controlling flow, steel quality and temperature in tundish not yet solved by furniture systems. It addresses the limited ability of the tundish vessel in controlling the flow of molten metal.

Tundish EMS is placed on the outside of the tundish and uses non-contact electromagnetic stirring technology to generate an electromagnetic field that creates a stirring effect in the bath melt. This continuous stirring significantly increases mixing zone volume for virtually the entire tundish, with higher flow speeds, elimination of dead zones and homogenization of temperature.

Adoption of this electromagnetic stirring technology will be particularly important for steelmakers with multiple casting strands coming from one tundish. It will mean greater removal of inclusions, resulting in smoother, cleaner steel and reductions in nozzle clogging.

ABB launched the product following a successful pilot project in China in partnership with the engineering company Zenith. The process conditions included GCr15 (bearing steel), a casting speed of 0.76m/min and tundish throughput of 1.25–1.9 ton/min. The results included increased temperature homogeneity in the tundish (a difference of 1.1°C with the EMS vs 2.5°C without) and superior temperature stability during sequence casting (tundish temperature is 6°C lower with the EMS and the average temperature variation was 2.8°C lower).

ABB offers the world's most comprehensive range of EMS for both steel and aluminium production processes, delivering metallurgical improvements that are proven to increase productivity, end-product quality and reduce operating costs for electric arc, ladle and aluminium furnaces, as well as thick and thin slab and billet and bloom casters.
