EMS electromagnet stirrer for Slab

1. Electromagnetic Stirrer for slab.
2. Have all types of the electromagnetic equipments for slab.
I. M-EMS for slab
Two coils shall be installed along width direct between meniscus and side hole of outlet. Fed by triphase power, it will produce traveling wave field. It is mainly used for medium and thick slab with low casting speed.

II. S-EMS for slab
EMS behind the rollers
EMS is installed behind the rollers, in one side or each side. It needs little change of caster and installation is simple. It can be moved promptly when breakouts happen. Stirring freq: 0.5 ~ 5Hz.
EMS inserting the rollers
Two coils are installed in each side of the curve. The head of EMS is small to insert between rollers and be near to slab. Stirring effect is good for its high efficiency and low energy consumption. freq: 6~ 20Hz.Stirring EMS of roller type

EMS shall be made with the same size of the roller, and placed of rollers, installed in each side of the curve. These two couple stirring rollers are of CrNi heat-proof stainless steel. It is simple to install EMS without limit of caster size. Stirring freq is 2 ~ 5Hz.
