Title: Kenji Nakase: Innovator in Metal Processing Technologies
Introduction
Kenji Nakase is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of metal processing, particularly in methods for refining and removing impurities from metals. With a total of 4 patents to his name, Nakase's work has had a substantial impact on industrial practices.
Latest Patents
One of Nakase's latest patents is a method for removing phosphorus from phosphorus-containing substances. This innovative approach is applicable on an industrial scale and effectively reduces phosphorus levels in materials used for metal smelting or refining. The method involves reacting the phosphorus-containing substance with a nitrogen-containing gas at a treatment temperature lower than the melting temperature of the substance. This process allows phosphorus to be removed preferably in the form of phosphorus nitride (PN). Additionally, the nitrogen and oxygen partial pressures in the gas are controlled to minimize the load on the dephosphorization process.
Another notable patent by Nakase is a method for oxygen-blowing refining of molten iron. In this method, an oxygen-containing gas is supplied from an inlet side of a blowing nozzle, which passes through the outer shell of a top-blowing lance. The gas is blown from the nozzle while a control gas is jetted toward the inside of the nozzle during part of the refining process. This innovative design enhances the efficiency of the refining process.
