The rules of fluid rate with different technical parameters: the increase of electromagnetic force causes the increases of the fluid rates at S/L interface and free surface, the decrease of skin depth, the increase of electric current density which will make the fluid at free surface flowing faster, while it doesnt affect the fluid rate at S/L interface. When the height of melt increases, the both of fluid rates will increase too. The increase of the width-thickness ratio augments the fluid rates along the wider edges at S/L interface evidently, while the rates along the narrow edges will have little change, and the rate at free surface has little change too. The increase of overheat degree minishes the range of mush zone, while the fluid rates at S/L interface and free surface will increase evidently.

流速的大小随各种不同工艺因素的变化呈现出一定的变化规律：随电磁力的增大，固液界面以及自由表面处的流速都会增大；集肤层渗入深度变薄，电流密度增大，会导致自由表面上流动的加强，但对固液界面处的流动速度影响不大；熔区高度的增加，也会使固液界面及自由表面处的流动增强；宽厚比增大时，固液界面上沿宽面方向的流动显著增强，但窄面方向流速变化不大，同时自由表面上流速变化也较小；过热度及温度梯度的增大，使糊状区减小，导致固液界面及自由表面处的流速显著增大。

In most cases the short circuit current has already damaged the thyristors until this time.
