EMS - Electromagnetic stirrer - ergolines lab - Trieste (Italy) 

The electromagnetic stirrers are used in the continuous casting
process to improve the product quality and to increase the steel
production. According to the position along the casting strand
and metallurgical effects, stirrers can be classified mould, strand
and final stirrers. The benefits obtained using one or more EMS in
combination include surface and sub-surface quality, internal and
central soundness as segregation, porosity and central cracks.
