Latest Patents
Yun Li's latest patents include a degassing method for manufacturing steel. This innovative method involves tapping liquid steel out of a primary steelmaking furnace and deoxidizing it before transferring it to a ladle metallurgy furnace. The process includes removing sulfur at the ladle metallurgy furnace, adding fluxes and deoxidizers to the ladle slag, and skimming off ladle slag to prevent sulfur reversion. The liquid steel is then transferred to an RH degasser for carbon removal by blowing oxygen. This method ensures ultra-low levels of carbon, nitrogen, sulfur, and titanium in the NGO steel, which provides excellent magnetic properties. Another notable patent is the degassing method for manufacturing ultra-low carbon, nitrogen, sulfur steel. This method also emphasizes the importance of removing oxygen and sulfur prior to transferring the liquid steel to the RH degasser, facilitating nitrogen removal and preventing carbon pickup.
