Latest Patents
Iwaki's latest patents include a "Method for Preliminary Treatment of Molten Iron" and a "Method of Refining Molten Iron." The first patent proposes a method for preliminary treatment of molten iron that ensures a sufficient heat source for dissolving scrap. This method aims to improve iron yield while efficiently 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, conducting desiliconization, and then performing intermediate slag removal before adding a lime-based flux solvent and blowing oxygen for dephosphorization.
The second patent outlines a molten iron refining method that involves charging molten iron and a cold iron source into a converter-type refining vessel. This method includes supplying a material containing CaO along with an oxygen source to dissolve the cold iron source and conduct desiliconization. It also emphasizes the importance of removing a portion of the produced slag as an intermediate step and adding a slag-forming agent for effective dephosphorization.
