Roller Hardening is a specialized heat treatment process used to increase the surface hardness and wear resistance of rollers. This is achieved through induction heating or flame hardening, followed by rapid quenching. The process helps to improve the durability of the rollers, enabling them to withstand high pressure, friction, and wear in various industrial applications. Roller hardening is commonly used in industries like printing, steel manufacturing, textiles, and paper production to enhance the performance and longevity of rollers, which are essential components in these processes.
