The paper presents the results of a project performed under the conditions of the Re Alloys plant for the production of aluminum ferrosilicon having a silicon and aluminum content equal to 55–75 and 4–20 wt%, respectively, in a six-electrode submerged arc furnace equipped with two 7.75 MVA transformers. The experience of development and incorporation of the aluminum ferrosilicon smelting technology into the industrial activity of the plant is recounted. Additionally, the paper describes the results of the work carried out within the framework of the project on the selection of charge materials, in particular, waste raw materials with a high Al2O3 content, as well as the optimization of both the charge composition and the technological mode of the submerged arc furnace in order to maximize the degree of aluminum and silicon extraction into the finished alloy.
