Реферат

For ferrous metallurgy, of scientific and practical interest is the development of technology for processing metallurgical and mining sludge as an additive to produce high-strength pellets with a high content of iron-containing phase for subsequent use as a charge. An increase in the amount of reduced iron for hematite quartzites is achieved by increasing the volume of calcinated coke as a reducing agent, which opens up the possibility of working with difficult-toprocess ores, the reserve potential of which is unlimited. Most of these works are related to the effect of carbon components on iron-containing phases, mainly for non-pelletizing ore materials, as well as powders. A 2 % mixture of red mud (RM) with nepheline extracted from saponite ore sludge by flotation was used as a binding material. As an iron reducer from the hematite phase, coke calcinated at a temperature of 1600 °C was added in an amount of 0.5 to 3.5 %. To study phase transformations, pellets measuring from 12 to 16 mm were obtained in a laboratory plate pelletizer from hematite quartzites and heat-treated at temperatures from 1100 to 1200 °C. The compressive strength with the addition of calcinated coke of more than 3.5% was established, which is 240–250 kg/sample. Calculation of economic indicators has been carried out. An annual reduction of financial risk and capitalization ratio by 10 % will ensure the stable development of pelletizing production using the proposed technology. A Burn rate indicator of 8 to 9 % guarantees the stability of the development of new pelletizing technology in a highly competitive environment. It has been established that the involvement in the processing of difficult-to-process raw materials (hematite ores, nepheline and RM) establishes the demand for poor pellets when blended with rich pellets in blast furnace iron production.
