MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090284 A) filed by Jfe Steel Corporation on July 24, 2026, for Molten Material Height Detection Method, Molten Material Height Detection Device, And Molten Material Production Method.
Inventors include Iwanaga, Taiki; and Matsunaga, Ryotaro.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: This method for detecting the height of a molten material is for detecting the height of a molten material in a blast furnace, said method comprising: a step for measuring vibrations at at least one position of a furnace wall in a furnace lower part of the blast furnace; a step for analyzing the frequency of the vibrations and calculating the vibrational intensity of a frequency correlated with vibrations generated upon introduction of a gas into an inflow port of the furnace lower part; and a step for detecting the height of the molten material inside the blast furnace using a corrected vibrational intensity obtained by removing, from the vibrational intensity of the frequency, the influence of a blast amount of the gas introduced from the inflow port and a physical property of a filling layer which exists in the furnace lower part.
