Title: Keikichi Murakami: Innovator in Metal Production and Refining
Introduction
Keikichi Murakami is a notable inventor based in Kobe, Japan, recognized for his contributions to the field of metal production and refining. With a total of eight patents to his name, Murakami has developed innovative methods that enhance the efficiency and effectiveness of metal processing.
Latest Patents
Among his latest patents is a molten metal producing and refining method. This method is designed to avoid damage to the apparatus while achieving a stable and high second combustion rate. It effectively recovers heat generated by the second combustion. The process involves introducing a metal-containing material, a carbonaceous material, a flux, and O₂ gas into a furnace. The carbon dissolves into the metal bath from the carbonaceous material and combusts with the O₂ gas to generate heat and CO gas. The CO gas undergoes a second combustion with O₂ gas in the slag bath, allowing for efficient melting and refining of the metal-containing material.
Another significant patent is the method of smelting reduction of ores containing metal oxides. This method involves prereducing the ore in a solid state in a prereduction furnace, followed by melting and final reduction in a smelting reduction furnace. The process also introduces gas generated in the smelting reduction furnace into the prereduction furnace, optimizing energy utilization.
