MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617076087 A) filed by Jfe Steel Corporation on June 19, 2026, for Blast Furnace Control Method And Control Device.
Inventors include Matsunaga, Ryotaro; and Yamamoto, Tetsuya.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A blast furnace control method according to the present invention includes: a temperature distribution estimation step for estimating the temperature distribution of a blast furnace bottom section by executing heat transfer analysis using a blast furnace numerical model; a determination step for determining the risk of generation of a molten iron flow failure region at the blast furnace bottom section on the basis of a difference value between the temperature distribution estimated in the temperature distribution estimation step and an actual measurement value of the temperature of the blast furnace bottom section; and a control step for controlling blast furnace operation conditions on the basis of the determination result in the determination step so that a molten iron flow failure region is not generated.
