| Abstract Scope |
In the present paper a reduced order model framework for material flow through a furnace tapping system incorporating the furnace interior, tap-hole, transfer launder, and tapping ladles is presented. The framework is based on governing equations based on fundamental pressure and mass balances, and uses simplified descriptions of each component in the tapping system to obtain an overall model. The utility of the resulting model is assessed by comparison to real-world tapping data obtained from an operating silicomanganese submerged arc furnace. Strengths and weaknesses in the model are subsequently identified and discussed in the context of the potential for such models to act as operator guidance and digital twinning tools. In particular, the effect of parameters which are able to change randomly from tap to tap is assessed in terms of their impact on the confidence associated with the model’s predictions. |
