Title: The Innovative Mind of Takamasa Ohno
Introduction
Takamasa Ohno, an accomplished inventor based in Hikari, Japan, has made significant contributions to the field of metallurgy. With a total of three patents to his name, Ohno has dedicated his career to developing methods that enhance the efficiency and quality of metal processing.
Latest Patents
One of his notable inventions is a method for spectroscopically determining the composition of molten iron. This innovative technique involves blowing oxygen or a mixed gas containing oxygen against the surface of the molten iron, causing radiation emission. By measuring the emission spectra of the resulting radiations, the composition of the molten iron can be accurately determined.
In addition, Ohno has developed a method for the dephosphorization of metal or alloy. This process targets carbon-unsaturated molten metals or alloys that contain elements such as chromium and silicon, which are more oxidizable than iron. By adding a flux composition of calcium carbide and a halide of an alkali earth metal like calcium fluoride in a non-oxidizing atmosphere, the method allows for effective dephosphorization. Notably, this technique is particularly useful in the refining of ferrochromium or crude stainless steel, leading to the economical production of low phosphorus stainless steel.
