General Description of the Electromagnetic Stirrer
In principle, Electromagnetic Stirrer (EMS) can be regarded as a rotary motor stator and liquid steel as rotator. EMS is placed lower in the mould to make the liquid metal rotate in the mold. The magnetic field penetrates the copper mould tube, stainless steel baffle tube, and any solidified shell and gives rise to induced currents in the melt. These interact with the traveling magnetic field and create a torque on and by that a movement of the molten steel. General speaking, EMS can be usually placed in one of three locations (Refer to drawing below):
Electromagnetic stirrer

1. Mould Electromagnetic Stirrer (MEMS): EMS is mounted outside copper tube.
2. Strand Electromagnetic Stirrer (SEMS): EMS is mounted outside billet.
3. Final Electromagnetic Stirrer (FEMS): EMS is mounted outside billet.
We seldom use the second mode now, but usually use the first or the third one, or use the two sorts in the same time.The metallurgical effects differ from different locations.

Technical Features of KEMEIDA EMS
*A new algorithm has been developed by KEMEIDA and GL Electromagnetic Field Software Co., names AGILD EM STIRRING ALGORITHM, which uses New Strip Magnetic Field Differential Integral Equation.
*This software can design electromagnetic parameters optimized. EMS shall be with high magnetic induction and stirring force. So stirring effect shall be great.
*Stirring force can be calculated by this software according different freq and current. So the best freq and current can be provided for user.
*Optimized design shall be done for L/D. Iron Core length shall be increased properly. So stirring effect shall be improved.
*Kemeida has also other software for designing F-EMS to calculate best position of F-EMS.
*KEMEIDA EMS uses low voltage and large current, which can avoid damage of peak voltage to insulation. It shall make reduce current leakage and prolong EMS life.
*Freq range shall be widened for choosing the best freq.
*Put EMS lower properly to make magnetic field around meniscus as little as possible to ensure strong magnetic field.
