Metallurgical Effect

Electromagnetic stirrer different mounting positions for different blank shape metallurgical results achieved are different.

In terms of the radius of the blank:

* Mold electromagnetic stirring almost all projects have a role, and therefore the most used.
* Solidification - EMS - EMS generally used in conjunction with special needs to improve in high alloy steel, high carbon steel center segregation and center when using the maximum shrinkage.
*, So the same with very little but not as mold electromagnetic stirring and mold electromagnetic stirring in the secondary cooling zone.
On the slab in terms of:
* Mold electromagnetic stirring effect of generous than small slab of less than 4 obvious, can effectively improve the surface quality of the slab, the internal inclusions and bubbles.
* Casting mold electromagnetic flow control (including electromagnetic brake, electromagnetic acceleration, deceleration electromagnetic, FC Mold) all have a role Precursor Form, can significantly improve the surface quality of the slab, the internal inclusions and bubbles.
* Secondary cooling zone of electromagnetic stirring using the most suitable slab linear mixing method, a substantial increase in the range of stirring, which can be very significant improvement in the slab internal cracks, center segregation, a substantial increase equiaxed rate, so the most used.
