Latest Patents
One of Washio's latest patents is a decarburization refining process for chromium-containing molten metal. This method involves a top blowing lance designed to suppress dust formation and chromium loss due to oxidation while achieving high productivity. The process entails blowing gaseous oxygen into the molten metal using a lance equipped with multiple gas blowing nozzles. The design includes a sub-nozzle at or near the lance axis and several main nozzles positioned at the lance's outer section. This innovative approach allows for effective decarburization when the carbon content in the molten metal is approximately 1 wt % or more.
Another notable patent focuses on the decarburization of molten steel containing chromium. In this method, oxygen gas, inert gas, or a mixture of both is blown onto the surface of the molten steel bath and below its surface. The process is designed to stir the slag and molten steel, facilitating a reaction that enhances the refining of chromium-containing steel.
