Title: Zhihe Dou: Innovator in Metal Processing Technologies

Introduction

Zhihe Dou is a prominent inventor based in Shenyang, China. He has made significant contributions to the field of metal processing, holding a total of 5 patents. His innovative methods focus on improving the efficiency and effectiveness of metal production processes.

Latest Patents

Zhihe Dou's latest patents include a "Method for iron making by continuous smelting reduction." This method involves several steps, such as mixing iron-containing mineral powder with a reducing agent and a slag former to create mixed powder materials. The process continues with placing furnace startup materials in a reducing furnace, heating them to form a molten pool, and conveying the mixed powder materials into the furnace. The method also includes stirring to create a molten slag layer and a molten iron layer, ultimately allowing for the continuous discharge of molten iron and reduced molten slag.

Another notable patent is the "Method for preparing high-melting-point metal powder through multi-stage deep reduction." This invention outlines a process that begins with mixing dried high-melting-point metal oxide powder with magnesium powder to initiate a self-propagating reaction. The intermediate product is then treated in a closed reaction kettle, followed by leaching with hydrochloric acid to obtain a low-valence oxide precursor. The method culminates in a vacuum reduction process to produce high-melting-point metal powder.
