The EMS can be applied in continuous casting, achieving the effect of improving steel quality.
1. Long service life.
2. High efficiency of magnetic field stirring.
Three--dimensional analysis software of modern computer is adopted to process optimum design on the distribution space of electromagnetic field inside the mould, so as to make the distribution of electromagnetic field of EMS be more reasonable and the generated magnetic field force be more efficient;
3. Excellent metallurgical effect
Under the premise of meeting the requirement of the EMS installation, the stirring scope of EMS is designed to be increased as far as possible. It can not only increase the effective working height of magnetic field in the EMS, make magnetic field distribution more homogeneous, but also improve the molten steel stirring force and extend the stirring time, creating conditions for further improving the casting speed and increasing output;
4. Low consumption
High quality silicon steel is adopted for the iron core, which increases the intensity of magnetic field inside the EMS and improves the iron core saturation of EMS, at the same time decreases the consumption of EMS itself.
The splitting type in-roll electromagnetic stirrer(EMS) is designed to make it applicable to continuous caster with a plate width of 1800mm or more. The splitting structure ensures the strength of the roller sleeve and prevents deformation; multiple stirring modes are available to improve the quality of the strand; The online time is long.
