The characteristic of the multi-function electromagnetic stirring technology of the mold is to control the flow in the mold, especially near the meniscus, by selecting and adjusting the direction and magnitude of the horizontal electromagnetic force applied to the flow stream from the SEN, depending on the different casting conditions.

 At high casting speed, the purpose is to brake the flow and reduce the flow speed near the meniscus to avoid instability or fluctuation of the meniscus;

 When the casting speed is low, the purpose is to accelerate the flow, improve the flow speed near the meniscus, so that the superheated steel will transfer heat to the meniscus; At the same time, it also improves the cleaning effect of the solidification front.

 Adjust the flow of molten steel when the casting speed changes during the abnormal casting period such as the beginning and end of casting and the ladle exchange period.
 

It can be seen that under different casting conditions, the flow in the mold, especially the flow near the meniscus, can be controlled in an optimal range by means of the multi-functional electromagnetic stirring device of the mold, so that the content of inclusions on the surface and under the skin of the casting slab can be greatly reduced.

  Reduced surface longitudinal cracks: Due to the uneven temperature of the casting strand in the width direction in the mold and the uneven thickness of the initial shell, the surface of the slab is prone to longitudinal cracking, especially for the low-C steel with C content of 0.10% to 1%. The use of MM-EMS evened out the temperature field of the meniscus part, reduced the delayed solidification part, and evened out the thickness of the shell, so that the longitudinal cracking index of the slab surface was reduced to 1/4 of the original.
