Abstract
Free convection of the slag-metal melt («bath») in a furnace with a bubble layer during its blowing in a bubble and jet modes is investigated using a mathematical model. It is established that bath motion velocities average by the bulk are larger by orders of magnitude than the velocities of its pneumatic mixing with flows for lifting bubbles and gas-liquid jets. The mixing work of the melt during the free convection, which is mainly performed in the tuyere plane, is anisotropic. Its value in the vertical bath plane reaches 1,25 MJ/t, while in the horizontal plane—does not exceed 43 kJ/t.
