Title: Yan Liu: Innovator in Metal Processing Technologies
Introduction
Yan Liu is a prominent inventor based in Shenyang, China. He has made significant contributions to the field of metal processing, holding a total of 9 patents. His innovative methods have advanced the techniques used in iron making and the preparation of high-melting-point metal powders.
Latest Patents
One of Yan Liu's latest patents is a "Method for Iron Making by Continuous Smelting Reduction." This method involves several steps, including 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 form a molten slag layer and a molten iron layer, allowing for continuous discharge of both materials.
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 to obtain a low-valence oxide precursor, which is further processed to yield high-melting-point metal powder.
