Modelling of ferroalloy production processes in the SAF and converter

ABSTRACT The modelling of different parts of Submerged Arc Furnace(SAF) used in ferroalloy production has been investigated and the summary showed that both 2D and 3D simulations will help to improve the process for ferroalloys production. However, most of the developed models are in lack of verification from the industry, which needs to be studied or improved in future. And the modelling on electrodes and lining of SAF is helpful for better understanding the inside environment of the furnace hence decreasing the breaking of electrodes, prolonging the lifetime of lining. Modelling of converters for ferroalloy refining - Creusot Loire Uddeholm (CLU)showed some useful results in terms of mass transfer coefficients, mixing times and plume characteristics.
