Presentation Title Modelling of Metal Loss in Ferromanganese Furnace Tapping Operations
Author(s) Quinn Reynolds, Jan Erik Olsen
On-Site Speaker (Planned) Quinn Reynolds
Abstract Scope During the pyrometallurgical production of industrial alloys such as ferromanganese in electric smelting furnaces, molten slag and metal phases are tapped from the unit at regular intervals. This involves opening a dedicated channel in the furnace sidewall (the tap-hole) and allowing the contents of the vessel to drain through it. After exiting the tap-hole, the stream of molten material is directed along open launders and empties into one or more storage ladles. Intermixing of slag and metal phases occurs frequently during the latter stages of the tapping process, and if not carefully managed, can result in significant metal being lost to the waste slag by entrainment. This paper presents the results of a computational fluid dynamics study of the multiphase free surface fluid flow in tapping launders and ladles, with a specific focus on the impact of various design and operational parameters on metal losses to the slag.
