Metallurgical principle
What Is The Principle Of Electromagnetic Stirrer?
Modern theory think that electromagnetic stirring can improve strand organization structure, which is mainly based on the following three points:

1. Changing the dynamics conditions during the solidification process (i.e., mechanical model theory);

2. Changing thermodynamics condition during the solidification process of (i.e., thermal model theory);

3. Improving material migration conditions during the solidification process (to make the components uniform).

The strong electromagnetic stirring force enable the un-solidified molten steel flush the end of the solidification, cut off and corrode the crystal arm of columnar crystal, forming a large number of dendrite fragments as crystal nucleus of equiaxed grain, making the grain multiplied grown, so as to inhibit the growth of dendrites.

Long service life.
High efficiency of magnetic field stirring.
Excellent metallurgical effect.
Low consumption.
Metallurgical Effect
The Main Application Of Electromagnetic Stirrer

The electromagnetic stirrers are used in the continuous casting process to improve steel quality and to increase the steel production. According to the position along the casting strand and metallurgical effects, stirrers can be classified mold, strand and final stirrers. 

The benefits obtained using one or more EMS in combination include surface and sub-surface quality, internal and central soundness.
