Claims10
A method for electromagnetic stirring of liquid metal in a continuous charge electric arc furnace, comprising:
- generating, using a plurality of electromagnetic stirrers, at least one first electromagnetic field along a first axis of electromagnetic stirring and at least one second electromagnetic field along a second axis of electromagnetic stirring,
- wherein the furnace has a cycle including a first step and a second step,
- wherein in the first step of the cycle of the furnace, said first electromagnetic field and said second electromagnetic field generate mixing forces axes of which are in directions opposite to each other on the liquid metal, and in the second step of the cycle of the furnace, said electromagnetic fields generate forces axes of which are in a concordant direction as each other on the liquid metal,
- wherein charging is performed in said first step and refining is performed in said second step.
