To accelerate the melting speed of aluminum, increase the reaction speed, and ensure the uniform composition of aluminum solution, it is necessary to stir. Each stirring will destroy the protective layer of aluminum oxide on the liquid surface, increasing the burning loss of aluminum. To this end, many units are studying stirring technology, although the emergence of mechanical harrows, but not very ideal.

 

Electromagnetic stirring system is a British enterprise research technology, suitable for a variety of reverberatory furnace and static furnace. The principle of electromagnetic stirring is to install the induction coil under or on the side of the furnace, and generate a traveling wave magnetic field after the electricity. The stirring (flow) of aluminum alloy solution in molten pool depends on the interaction between electromagnetic field and conductive metal liquid.

 

This is similar to the principle of an electric motor, where the stator is equivalent to a stirrer and the rotor is equivalent to a molten pool. Electromagnetic stirring can greatly reduce the burning loss, reduce the operation intensity, purify the environment, reduce the slag production, and obtain the uniform composition of aluminum alloy solution. The cost of electromagnetic stirring system is very high, and it needs enterprises with high capacity to build.
