Latest Patents
Pugh's latest patents include innovative methods for improving the chemistry and heat treatment of grinding rods. One of his patents describes a grinding rod chemistry that enhances wearability and durability. This involves achieving a surface hardness exceeding 55 Rockwell C through specific levels of carbon and chromium. The core of the grinding rod is composed of over 99% pearlite, with a hardness of less than 45 Rockwell C, while the end portions are designed to be softer, with a hardness of less than 35 Rockwell C. The method includes reheating the steel bar to above its austenitising temperature and utilizing a quench vessel to ensure uniform heat removal, followed by tempering the outer martensite shell.
Another patent focuses on a stress-relieved grinding rod that features a hardened outer shell of tempered martensite. This design is specifically adapted for heavy-duty grinding environments. The rod is stress relieved to minimize internal compressive stresses, ensuring stability against break-up caused by balancing tensile stresses in the pearlitic core.
