Advanced patented technology Mold Electromagnetic Stirrer for continuous casting machine(CCM)

The mold electromagnetic stirrer (M-EMS) is installed in the mold zone. The movement of unsolidified molten steel is accelerated through the electromagnetic force generated by the electromagnetic stirring, thereby changing the flow, heat transfer and migration process of the molten steel during the solidification process, so as to achieve the purpose of improving the quality of the billet.
It can control the surface quality and subsurface quality, which is reduce the inclusions, blowhole and airhole

Description

The mold electromagnetic stirrer (M-EMS) is installed in the mold zone. The movement of unsolidified molten steel is accelerated through the electromagnetic force generated by the electromagnetic stirring, thereby changing the flow, heat transfer and migration process of the molten steel during the solidification process, so as to achieve the purpose of improving the quality of the billet.

Function

It can control the surface quality and subsurface quality, which is reduce the inclusions, blowhole and airhole.

1) 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;

2) 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.

3) Increase the ratio of equiaxed grain zone; it can reduce segregation and porosity to a certain extent.
