An electromagnetic stirrer (EMS) uses electromagnetic induction to generate Lorentz forces within electrically conductive molten metals, producing controlled fluid flow without direct mechanical contact.
SATRAD supplies electromagnetic stirrers (EMS) for steelmaking and continuous casting applications.
An electromagnetic stirrer (EMS) is an industrial device that uses electromagnetic induction to generate Lorentz forces within electrically conductive molten metals, producing controlled movement and circulation of the liquid metal without direct mechanical contact. It is widely used in steelmaking and continuous casting processes to improve melt homogeneity, promote uniform temperature distribution, and enhance solidification conditions, contributing to improved internal quality of cast products.
Electromagnetic stirrers (EMS) are classified according to their installation positions and functions in continuous casting systems. SATRAD supplies different EMS configurations to meet specific caster designs, steel grades, strand dimensions, and operating requirements.
The electromagnetic stirrer is installed inside the mould of a continuous casting machine to stir the molten steel within the mould.
The electromagnetic stirrer is installed outside the mould of a continuous casting machine to stir the molten steel inside the mould.
The electromagnetic stirrer is installed in the first foot-roller zone outside the mould of a continuous casting machine to stir the unsolidified molten steel within both the mould and the cast strand.
The electromagnetic stirrer is installed in the secondary cooling zone of a continuous casting machine to stir the unsolidified molten steel within the cast strand in this zone.
The electromagnetic stirrer is installed at the final solidification zone of a continuously cast strand to stir the viscous molten steel within the strand at the final stage of solidification.
Electromagnetic stirrers are used in ferrous and non-ferrous metallurgy to improve melt homogeneity, control solidification conditions, and enhance process efficiency.
Improves solidification structure, promotes equiaxed grain formation, and helps reduce centerline segregation and internal casting defects in billets, blooms, and slabs.
Promotes melt homogenization, alloy dissolution, uniform temperature distribution, and desulfurization.
Promotes uniform melt temperature and chemical composition in aluminum, copper, lead, zinc, and their alloys, supporting consistent product quality and improved melting and casting efficiency.
A complete electromagnetic stirring system typically consists of an electromagnetic stirrer (inductor), a variable-frequency power supply, a matching transformer where required, a control system, and auxiliary cooling equipment.
Electromagnetic stirrers can be designed with water-cooling or air-cooling systems, depending on the equipment configuration, thermal load, and installation conditions. The cooling system helps maintain suitable operating temperatures and protects the electromagnetic coils during operation.
Electromagnetic stirrers can operate in continuous, intermittent, or alternating stirring modes, depending on the process requirements and equipment configuration.
