Thermal definition of a charge at recovery of calcium and magnesium in bulk of molten metal

With the purpose of definition of the power expedient thermodynamic scheme of processes of electro-thermal recovery of earth metals the cost analysis of an energy on passing of chemical reactions is made, including formation of complex oxides of Mg2SiO4, Ca2SiO4, CaAl2O4, Ca3Al2O6, MgAl2O4, Ca3Al2O6, CaAl2O4. Demonstrated during a deoxidation process under the scheme with binding of resultants of reaction in complex oxides, the temperature lowering at the a beginning of chemical reactions constitutes 5-35%, and thermal of a blend is reduced thus in 2-2,5 times. The analyses of a received results has shown, that from thermodynamic and power points of view the silicon reduction of calcium and magnesium is more preferable than a message with formation of Ca2SiO4, and alumothermal recovery with education of Ca3Al2O6. By results of researches the structures of mixes for obtaining of vaporous magnesium and calcium in bulk of molten metal are designed.
