Abstract
The necessity of studying the stirring of liquid-metal components to form homogeneous alloys is substantiated. A mathematical model is developed for the electromagnetic stirring of alloys produced in an electric arc furnace. A special-purpose experiment is carried out to test the proposed model. The results of calculations and experiments performed on a small electric arc furnace are presented. Good agreement of the proposed theory with the experimental results is reached, and recommendations are given for improving the existing technological equipment.
