Abstract
The article deals with the influence of operational aspects on the performance of the reduction process in reactors with submerged electrical arc. Experiments were conducted in the large-scale laboratory conditions in one-electrode furnace with a capacity of 200 kVA at Chemical and Metallurgical Institute (Karaganda, Kazakhstan). Also limited industrial research in the furnace with the capacity of 30 MVA at LLP ‘Tau-KenTemir’ was conducted.In the process of the research, evidence was achieved that increasing the interval between the furnace top treatments up to 30 minutes, and achieving a balance between the material and thermal flows in a reactor allow increasing silicon yieldup to 10-15% minimum. Fluctuations in the phase currentstabilize. It was proved that on the basis of the concept of balancing it is possible to bringan industrial reactor out of complex crisis statesrather quickly.
