| Abstract Scope |
Tapping is an experience based sub-process that is developed over time at the various plants. To expand the knowledge into the scientific world, CFD modelling, industrial campaigns and lab scale experiments has mbeen conducted. A variety of models have been developed describing the tapping rate. We also need to know the mechanisms affecting the tapping of industrial furnaces. Both industrial campaigns and investigations on mechanisms and material at the lab has been conducted. The industrial campaigns as an example been to excavate both Mn-ferroalloy and Si furnaces. In lab scale, the formation of TiC banks in the SiMn furnaces, the formation of slag and the formation of SiO gas in Si furnaces and the pressure build up in charges by fines, have been investigated. |
