Latest Patents

Hamagami's latest patents focus on innovative methods for producing ultra-low-carbon steel. One of his notable inventions involves a method of producing ultra-low-carbon steel by conducting vacuum-decarburization of molten steel using a vacuum degasifier equipped with recirculation pipes and a vacuum chamber. This method introduces hydrogen gas along with an inert gas into the molten steel when the carbon content reaches 50 ppm or less. The hydrogen can be injected directly into the molten steel or blown onto its surface to enhance the decarburization process. Another patent outlines a similar method that involves progressively reducing pressure in the vacuum degasser while adding hydrogen to achieve a carbon content of 25 ppm or below.
