MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202441016268 A) filed by Rashtriya Ispat Nigam Ltd., Visakhapatnam, Andhra Pradesh, on March 7, 2024, for 'preparation method of low-melting ladle flux from ladle furnace slag for treating silicon-manganese killed steels.'
Inventor(s) include Suguna Soumya; More Venu Madhava Rao; Santanu Dey; Ranjan Kumar Pathak; Veera Babu Gollapalli; Anil Kumar Tangudu; and Y. Lokeswara Rao.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure proposes a method for preparing low-melting ladle flux with recycled stabilized Si/Mn/Al killed ladle furnace slag, reducing melting point and simultaneously increasing the valorisation of ladle furnace (LF) slag. The proposed method reduces synthetic slag addition, resulting in cost savings. Furthermore, it notably improves slag fluidity, thereby diminishing reliance on synthetic slag. The low melting ladle flux is prepared in two methods, which one is by recycling as received disintegrated Si/Mn/Al killed Ladle Furnace slag and the other by recycling Si/Mn/Al killed Ladle Furnace slag after stabilizing with H3BO3 additions at industrial scale. The proposed method for preparing low-melting ladle flux with recycled stabilized ladle furnace slag is disclosed. The proposed invention provides the method that reduces synthetic slag addition, resulting in cost saving."
