Production of Ferrosilicoaluminium from Aluminum Slag and Local Ore Via Carbothermic Reduction

Abstract:

This paper deals with the possibility of obtaining FeSiAl complex alloy by carbothermic reduction in a submerged arc furnace using aluminum dross, mill scale and feldspar.Bench scale experiments are carried out to clarify the effect of different variants such as reducing agent, basicity, and mill scale content of the charge on the metallic yield and chemical composition of the produced alloy.It was possible to get FeSiAl alloy containing 22% Si and 18% Al. the results reveal that to obtain such alloy less than 20% mill scale must be involved in the charge and the coke with amount 1 stoichiometric must be used.
