Study of Some Factors Affecting the Production of Ferrosilicon Magnesium
Saeed Nabil Saeed Ghali;
Abstract
This study has been carried out to determine the optimum conditions for producing ferrosilicon magnesium alloy through in estigation @; different parameters affecting the production processes.
Two production techniques have been used to produce ferrosilicon magnesium alloy. In the first one, local calcinated dolomite oJe was reduced either by the silicothermic or
I
the aluminosilicothermic processes. In the second one, magnesium metal was immersed in
molten ferrosilicon.
For production of ferrosilicon magnesium alloy by reduction of Joe!calcinated dolomite, laboratory experimental heats were deJigned and carried out in small submerged electric arc furnace with transformer working ati480A and 44V. In these experimental heats, some factors affecting the reduction process such as: the amount of reducing agents, the composition of the magnesium ores and the typof the added fluxing materials (i.e. lime, fluorspar, bauxite and quartzite) have been investi ated. The optimum conditions for obtaining the highest recovery have been determined. I
Based on the results obtained from laboratory scale heats, different pilot plant heats were carried out in I 00 kVA pilot scale srbmerged electric arc furnace. The optimum charge composition and flux addition to attain the highest magnesium recovery have been deduced.
Other pilot plant experiments were also carried out in I 00 kVA submerged electric arc furnace to produce ferrosilicon magnesium Jlloy by immersion of magnesium metal in molten ferrosilicon. The proper technique for prodhcing a homogeneous alloy and' attaining the highest magnesium recovery was examined.
Based on the results obtained from the pilot plant heats carried out to produce ferrosilicon magnesium alloy by reduction and immersion techniques, the optimu)ll conditions were used to make an economic comparison betweJn the two techniques. •
