ВПЛИВ ДЕФОРМАЦІЇ КРАПЕЛЬ РОЗПЛАВЛЕНОГО МЕТАЛУ НА ЇХ РУХ ТА НАГРІВАННЯ В ШАРІ ШЛАКУ ПРИ ЕШП.

A simplified mathematical model of the processes of movement and heating of molten metal drops in liquid slag at ESR is proposed in two variants of problem definition: the drop preserves its initial spherical shape; the drop is deformed and takes the shape of a spheroid flattened in the direction of movement. It is shown that drop deformation makes an essential impact on the velocity and duration of its movement in the layer of slag, as well as on the drop surface area (at preservation of its volume), which determines the conditions of heating and interaction of drop metal with molten slag. It was proved that due to increase of surface area and lowering of movement velocity of larger diameter drops, their heating in the slag layer occurs more effectively, compared to spherical drops.
