Title: Itsuo Miyahara: Innovator in Chromium Reduction and Molten Iron Production

Introduction

Itsuo Miyahara is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of metallurgy, particularly in the reduction of chromium-containing materials and the production of high-purity molten iron. With a total of 6 patents to his name, Miyahara's work has had a lasting impact on industrial processes.

Latest Patents

Miyahara's latest patents include a method for reducing chromium-containing raw materials. The objective of this invention is to provide a method that achieves a high degree of chromium reduction. This method involves heating a mixture of chromium oxide and a carbonaceous reductant using radiation heating in a moving hearth furnace. The average rate of temperature increase during this reduction process is preferably 13.96°C/s or higher until the mixture reaches 1,114°C. Another significant patent is a process for producing molten iron. This process efficiently produces high-purity molten iron by feeding a raw material mixture containing a carbonaceous reducing agent, an iron oxide-containing material, and a CaO-containing material into a moving-hearth reducing furnace. The blending amount of the CaO-containing material is adjusted to ensure that the basicity of the slag generated in the melting furnace is 1.1 or more, with a feeding amount of 40 kg or less per ton of molten iron.
