| Abstract Scope |
In pyrometallurgy, reactors are typically lined with a refractory lining. However, owing to the extreme thermal and chemical conditions to which they are subjected, refractories degrade over time and often need to shut down for lining replacement. In many cases, the solution lies in the deliberate formation of a solidified layer on the reactor wall, i.e. freeze lining. This provides protection against the corrosive nature of liquid slags. The need to understand and control slag freeze lining formation is more important than ever, considering the current trend of metal demand increase, which requires higher production rates and thus more aggressive bath dynamics and faster degradation. A three-dimensional mixture solidification model was developed to simulate fluid flow, heat flux, and slag solidification. The model was used to predict freeze lining evolution in electric smelting furnaces and fuming furnaces. The goal is to share the preliminary results with the community. |
