Inventor includes Mizutani, Moritoshi.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: In this method for producing reduced iron using a shaft furnace, the burden on equipment is reduced by suppressing the amount that a reducing gas is heated by an external heater. The method for producing reduced iron using a shaft furnace according to the present disclosure is characterized by: including preheating an iron oxide starting material, obtaining a reducing gas by subjecting a starting material gas including at least 90 vol% hydrogen gas to prescribed processing, and reducing the iron oxide starting material and obtaining reduced iron by supplying the preheated iron oxide starting material into the shaft furnace and blowing the reducing gas into the shaft furnace; and the relationship to be satisfied by the preheating temperature of the iron oxide raw material and the temperature at which the reducing gas is blown in differs according to the prescribed processing.
