2021年10月12日 The smelting process uses coal as reductant with ilmenite for reduction into titania-rich slag with 75–85% of TiO 2 content. An electric arc furnace was used in Australia for smelting sand ilmenite. Spherical powder prepared by thermal plasma synthesis is not only used for powder metallurgy or additive manufacturing,
Electric Arc Smelting SpringerLink
2018年11月15日 The second highlight of this topic is the production of ferrosilicon in EAFs. This carbothermic reduction process takes place in submerged furnaces, either open or covered, from quartz, charcoal, mill scale, and fluxes such as limestone.3 In “Effects and Electrical Resistance of Metallurgical Coke and Semicoke on Silicon Recovery in an
Stereolithographic Additive Manufacturing of Zirconia
Zirconia electrodes with dendritic patterns were fabricated by stereolithographic additive manufacturing (STL-AM). A solid electrolyte of yttria-stabilized zirconia (YSZ) was selected for oxygen separation in the molten salt electrolysis of aluminum smelting without carbon dioxide excretion. Thereafter, 4, 6, 8 and 12-coordinated dendritic structures composed

Trends in Increasing the Capacity of Electric Furnaces for
This article analyzes smelting parameters of mass scale ferroalloys upon increase in furnace capacity on the basis of domestic and foreign data. It has been demonstrated that upon increase in the power of furnace transformers, the energotechnological parameters of furnaces operating by slagging and non-slagging carbothermic process are impaired. In
Additive manufacturing of ductile refractory high-entropy
Moreover, the size of ingots is strictly limited by the furnace and casting molds, making it hard to mass-produce RHEAs. Additive manufacturing, as a bottom-up technique, is transforming our ability to prepare metallic materials effectively. Compared to arc melting, additive manufacturing possesses more design freedom and efficient material usage.
