RESTORED IRON PRODUCTION LINE AND METHOD FOR OBTAINING RESTORED IRON Russian patent published in 2023 - IPC C21B5/00 C21B13/00 F27D17/00 

FIELD: reduced iron production.

SUBSTANCE: group of inventions is related to a production line of reduced iron and methods for producing reduced iron using said line. The line contains a blast furnace configured to reduce iron oxide, a reduction furnace configured to reduce iron oxide, a methane synthesis reactor configured to synthesize methane from blast furnace gas and/or blast furnace gas and hydrogen gas, a supercharger configured to inject methane gas synthesized in the methane synthesis reactor into a blast furnace, a reforming thermoreactor configured to carry out heating or heating-reforming of blast furnace gas and/or top gas and methane gas synthesized in the methane synthesis reactor to form a reducing gas, a reducing gas pump, configured to inject reducing gas into the reduction furnace, and a supply channel configured to supply top gas to the methane synthesis reactor and/or reforming thermoreactor.

EFFECT: ensures energy saving and reduction of CO₂ emissions during the production of reduced iron from iron oxide.
