The Mold Electromagnetic Stirrer (M-EMS) is strategically installed in the mold zone to enhance the quality of the billet. By generating electromagnetic force, the M-EMS accelerates the movement of unsolidified molten steel. This process alters the flow dynamics, heat transfer, and migration patterns of the molten steel during solidification, ultimately leading to improved billet quality.
It can control the surface quality and subsurface quality, which is reduce the inclusions, blowhole and airhole.
◆ The scouring effect of the convective molten steel at the solidification front makes the solid-liquid interface smooth, and the inclusions larger than 5 microns are difficult to stick. That is, the subcutaneous inclusions of the casting section larger than tens of microns disappear; it is helpful to eliminate the bubbles formed in the molten steel and the gas formed by excessive lubrication oil;
◆ The rotating force causes the molten steel to be subjected to centrifugal force, and the inclusions with lighter specific gravity are subjected to centripetal force. The centripetal movement of the inclusions causes them to accumulate. The size of the inclusions becomes larger, and the floating speed accelerates, leading to the disappearance of accumulation of inclusions at the 1/4 inner side of the strand for curved CCM.
◆ Increase the ratio of equiaxed grain zone; it can reduce segregation and porosity to a certain extent.
