MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517050780 A) filed by Jfe Steel Corporation, Tokyo, on May 27, for 'molten material height detection method, molten material height detection device, and molten material producing method.'

Inventor(s) include Matsunaga Ryotaro; Moriya Kota; and Yamamoto Tetsuya.

The application for the patent was published on June 13, under issue no. 24/2025.

According to the abstract released by the Intellectual Property India: "Provided is a method for detecting the height of a molten material, in which a frequency, at which the height of the molten material in a blast furnace can be detected, can be easily specified, and the height of the molten material can be detected by using the vibration intensity of the frequency. Provided is a molten material height detection method for detecting a molten material height in a blast furnace, the method comprising: measuring vibrations at one or more positions on the furnace wall in the lower part of the blast furnace; calculating the vibration intensity at a frequency that is correlated with the vibration that occurs when gas is introduced into the inlet at the lower part of the furnace by analyzing the vibration frequency; and detecting the height of the molten material in the blast furnace by using a corrected vibration intensity obtained by removing the influence of the amount of gas blown from the inlet from the vibration intensity of the frequency."

The patent application was internationally filed on Sept. 05, 2023, under International application No.PCT/JP2023/032420.
