Electromagnetic Stirrer for Model Designation
EM BRAKE: EMBR and FC Mould
M-EMS: EMS can be installed inside or outside the mould.
S-EMS: there are three modes: behind the rollers; inserting the rollers; roller type.
M-EMS for slab
Installation Position of EMS for Slab Caster
Mould-EMS for slab
Four coils shall be installed along wide sides of mould. With combination of traveling magnetic field. rotation, acceleration & deceleration of molten steel can be achieved.
Strand-EMS for slab
IN-ROLL EMS ( roller type )
EMS has the same sizes of the roller, installed face to face along the strand (2 paires of 1 pair) instead of existing rollers.The casing is made of special stainless steel. Stirring freq is 2 ~ 5Hz.
EMS behind the rollers
EMS of roller type
EMS inserting the rollers
Metallurgical Effect of EMS/EMBR for Slab
| NAME | METALLURGICAL EFFECT | STEEL GRADES |
| EMBR | IReduce slag Improve inner struction Reduce wave of liquid metal |
Thin slab |
| MEMS | Make surface temperature of slab symmetrical Reduce cracks & improve surface quality Control speed of liquid steel |
Medium and thick slab |
| SEMS | Make equiaxed zone fine Reduce central porosity and segregation Improve inner quality |
