Title: Inventor Les Hart: Revolutionizing DRI Processing Techniques
Introduction
Les Hart, an innovative inventor from Baton Rouge, Louisiana, has made significant contributions to the field of steel production through his patented methods for reclaiming and inhibiting the activation of DRI (Direct Reduced Iron) dust and fines. With two patents to his name, Hart's work plays a crucial role in enhancing the efficiency and sustainability of DRI processing.
Latest Patents
Les Hart's latest patents focus on novel methods for managing DRI materials. The first patent reveals a method for reclaiming and inhibiting activation of DRI dust and fines. This method involves forming a moving stream or pile of DRI pellets and fines, which are then coated with a mixture of alkanes within the C15 to C40 range. This coating causes the fines to adhere together and to the DRI pellets, resulting in the formation of agglomerates that can be efficiently used in steel production. The coating material can be applied at a rate of 0.2 to 2.0 gallons per ton of processed DRI and may consist of mineral oil.
The second patent similarly addresses the reclaiming process, utilizing a coating material with a melting point between 70°F and 200°F. This coating incorporates at least one antioxidant and a carboxylic material, including coatable fatty acids or esterified derivatives. Selected materials for this invention include palm oil, coconut oil, and their ester derivatives, along with antioxidants such as butylated hydroxytoluene and vitamin E. These advancements aim to enhance the adherence of DRI fines to the pellets, forming agglomerates for more efficient steel production.
