With the crucible smelting lowgrade iron alloy is around 1860 began. Later developed with a blast furnace smelting ferrosilicon and silicon containing is less than 12% ferrosilicon. From 1890s to 1910s in France began to use electric arc furnace production of ferroalloy. H.
Silicon is also used as a secondary smelting additive in the manufacture of photonic devices and in the manufacture of industrial refractories. Silicon metal is commonly produced by smelting submerged electric arc furnaces, which is an energyintensive process.
Silicon Carbide is well known in the ferro alloy industry as a powerful reductant that can increase the performance of furnaces. Its use has been limited because lumpy silicon carbide is difficult to use in the ferro alloy process: It can react too early in the production process.
A process for producing ferromolybdenum alloys by thermite smelting of a particulated reaction mixture composed of a molybdenum oxide concentrate, an iron bearing material, a reductant and a slag fluxing agent present in controlled proportions. The reaction mixture is progressively charged into a refractory crucible and is exothermically reacted to produce a molten mass of ferromolybdenum ...
