Latest Patents

Ejima holds a patent for a "Method for Preliminary Treatment of Molten Iron." This method proposes a technique for the preliminary treatment of molten iron, ensuring a sufficient heat source for dissolving scrap. It improves iron yield while effectively decreasing phosphorus concentration by minimizing the amount of flux solvent used during desiliconization, dephosphorization, and decarburization. The process involves charging molten iron into a converter-type container for desiliconization, followed by intermediate slag removal. A lime-based flux solvent is then added while blowing oxygen to conduct dephosphorization. This method allows for the repeated treatment of newly untreated molten iron within the same container.
