Electromagnetic agitators are widely used in the field of steel smelting, especially in the process of continuous

casting. It strengthens the convection, heat and mass transfer process of molten steel by the electromagnetic

force generated, so as to control the solidification process of the casting billet. This technology has a positive effect on improving the quality of casting billet.

The principle of electromagnetic agitator is mainly based on electromagnetic induction and

electromagnetic force action. Here’s a detailed explanation of how it works:

When the electromagnetic agitator is working, the power supply will provide electrical energy to the

stirring coil, causing an alternating electromagnetic field to be generated in the coil. This electromagnetic

field penetrates into the liquid to be stirred, such as molten steel. Due to the presence of conductive

materials in the liquid, such as ferromagnetic powders or metal particles in molten steel, electromagnetic fields induce an electric current in these conductive materials.

The induced current interacts with the local magnetic field, creating an electromagnetic force. This

electromagnetic force is a volume force, acting directly on the liquid volume element. These electromagnetic

forces push the liquid to move, thus achieving the effect of stirring.

By adjusting the parameters of the electromagnetic stirrer, such as the current intensity, frequency and the

configuration of the stirring coil, the intensity and direction of stirring can be controlled, so as to achieve accurate control of the liquid mixing.

Electromagnetic agitators are widely used in steel smelting, non-ferrous metal smelting and other industrial fields.

It can not only improve the homogeneity of the melt, reduce the segregation of components, but also improve the crystal structure of the billet and improve the quality of the casting.

In general, electromagnetic agitator is an efficient and controllable stirring equipment by using electromagnetic

induction and electromagnetic force to achieve forced convection and uniform stirring of liquid.
