Title: Innovations in Steel Manufacturing by Zhiyou Du
Introduction
Zhiyou Du is a notable inventor based in Croton-on-Hudson, NY (US), recognized for his contributions to the field of steel manufacturing. With a total of four patents to his name, Du has developed innovative processes that enhance the efficiency and effectiveness of steel production.
Latest Patents
Zhiyou Du's latest patents focus on a two-stage reaction process for the manufacture of steel from iron carbide. This process is carried out in two separate but interrelated reactors. In the first reactor, iron carbide, along with slag formers, is introduced at the feed end. The reaction is optimized through the vessel geometry, stirring action, below-surface injection of oxygen, and the evolution of gases from the liquid metal bath. The resulting product, which contains approximately 0.5-2% carbon, is then transferred to the second reactor for further refinement using subsurface-injected oxygen. This second reaction is autogenous, with the evolved carbon monoxide being redirected to the first reactor, where it is combusted with oxygen in a foamy slag. This innovative approach not only enhances the efficiency of the steel production process but also contributes to sustainability by utilizing off-gas heat for preheating iron carbide.
Career Highlights
Throughout his career, Zhiyou Du has worked with prominent companies such as Praxair Technology, Inc. and U.S. Steel Corporation.
