| Abstract Scope |
Top-blowing bath smelting reactors are mature solution for smelting and converting reactors in the (non-)ferrous pyrometallurgy. From a process perspective, the defining characteristic of a top-blowing approach is the injection of process gas (typically via lance system) into a molten bath. This configuration directly converts gas momentum and buoyancy into strong turbulence and large-scale cavity within the bath – this mixing and bath formation is a central component of process kinetics.
Given the complexity and critical importance of this topic, a comprehensive understanding of the interactions between a high-velocity gas jet and the surface of the melt is essential. Unique fundamental experiments on cavity formation were performed using GaInSn and SnBi alloys, in which a supersonic gas jet is injected top-down on the surface.
In parallel, numerical models are used to simulate in detail fundamental flow phenomena such as gas jet penetration, the movement of the gas-metal interface and typical droplet formation. |
