Title: Innovations by Hui Yao in Heat Treatment of Steel Rails

Introduction

Hui Yao is a notable inventor based in Panzhihua, China. He has made significant contributions to the field of materials engineering, particularly in the heat treatment of hypereutectoid steel rails. His innovative methods have the potential to enhance the performance and durability of steel products used in heavy rail applications.

Latest Patents

Hui Yao holds a patent for a method for heat treatment of hypereutectoid steel rail. This invention involves a multi-stage cooling process that begins with holding the temperature of the steel rail above 900°C after rolling. The method includes a first cooling stage that reduces the temperature of the railhead surface layer to 700-750°C, followed by a second cooling stage to 550°C, and a third cooling stage to 450°C or less. This process not only improves the tensile properties of the steel rail but also effectively reduces secondary cementite, providing excellent resistance to abrasion and contact fatigue. The resulting product is particularly suitable for heavy rails.
