Abstract: The jet-flow of hot metal from the blast furnace has a certain initial kinetic energy. In addition, the tapping channel has a certain degree of slope. An innovative metallurgical reactor using the gravitational potential energy of the hot metal was proposed. On the basis of turbulent model and multiphase flow model, the fluid flow and the free-surface shape with VOF (volume of fluid) model in metallurgical reactor was numerically simulated, which was verified by the water model. The results show that the best swirling flow is formed in the bowl-shape reactor compared with other shapes. The curve of residence time distribution (RTD) obtained from experiment is in good agreement with the simulated result. The effect of swirling flow in bowl-shape reactor is greater than the others, which produces the most intensive and stable swirling flow.

Key words: gravitational potential energy, stirring characteristics, metallurgical reactor, numerical simulation
