Introduction

Keisuke Mizobata is a notable inventor based in Tokyo, Japan. He is currently employed at JFE Steel Corporation, where he contributes to advancements in steel production technologies. Although he has not yet been granted any patents, his work is significant in the field of metallurgy.

Latest Patent Applications

Mizobata's latest patent applications include innovative methods aimed at improving the quality and efficiency of molten steel processing. One of his applications is titled "Treatment Method of Molten Steel and Steel Production Method." This method focuses on preventing metal components in molten steel from being reoxidized by reacting with oxides in molten slag. It also aims to inhibit the occurrence of inclusions and reduce nitrogen levels in the molten steel. The process involves applying a potential difference between the molten steel and the molten slag using a direct-current power supply through two electrodes. The method includes a deoxidation step where a deoxidizing agent is added to the molten steel, followed by the application of the potential difference.

Another application is for a "Molten Steel Refining Method," which enhances the circulating rate using an RH vacuum degassing apparatus. This method determines the immersion depth of an immersion tube into molten steel and the circulating gas flow rate to optimize stirring power energy density. The formulae used in this method ensure that the refining process is efficient and effective.
