Electroslag Technologies for Saving Resources and Energy

Options for applying electrothermal technologies in electrode furnaces using slag in various metallurgical processes and electrotechnological complexes to solve urgent problems of energy saving and resource conservation are examined. An analysis of the experience of using electroslag technologies in metallurgy and mechanical engineering supplemented with physical and mathematical modeling of electromagnetic fields has shown that these technologies can be used not only for the production of ingots and parts of complex shapes, but also for redox processes that allow allothermal gasification of carbon-containing fuels and processing of solid waste. Based on electroslag technologies, electrotechnological complexes can be developed that use any types of solid fuels and state-of-the-art technologies for generating electric and thermal energy. Electrotechnological complexes can be regulators of the operation of electric-power systems. Promising directions for the development of electroslag technologies for the creation of new facilities with high energy efficiency and deep processing of the mineral part of fuels have been identified.
