Title: The Innovative Contributions of Ronald D Gray

Introduction

Ronald D Gray is a notable inventor based in Bethel Park, Pennsylvania, recognized for his significant contributions to the field of metallurgy. With a total of seven patents to his name, Gray has developed innovative methods that enhance the production of titanium oxides and high-purity iron. His work has implications for various industries, particularly in steelmaking and materials processing.

Latest Patents

One of Gray's latest patents is a "Method for producing beneficiated titanium oxides." This invention involves a method and apparatus utilizing a modified rotary hearth furnace, known as a finisher-hearth-melter (FHM) furnace. The process includes coating the refractory surface of the hearth with carbonaceous hearth conditioners and refractory compounds. Pre-reduced agglomerates are charged onto the hearth, leveled, heated until molten, and reacted with carbon and reducing gas burner gases. This results in the conversion of residual iron oxide to low-sulfur iron, producing fluid slag rich in titanium. The melted agglomerates are then cooled and separated from the hearth conditioner for recycling.

Another significant patent is the "Method for producing molten iron in duplex furnaces." This invention describes a method for operating a moving hearth furnace in conjunction with an electric melter to produce high-purity iron with low sulfur and phosphorus content. The process involves pre-reducing iron and carbon-bearing agglomerates, followed by continuous feeding of intermediate carbon-containing metallized iron into an electric melter. The method ensures minimal ingress of undesirable gases while maintaining elevated temperatures, resulting in a high iron content product suitable for the steelmaking industry.
