The Continuous Roller Hearth Furnace (CRHF) from HIGHTEMP is an advanced heat treatment solution designed for the continuous processing of metal components, especially for carburizing and hardening applications. This furnace is engineered to enhance the surface hardness and wear resistance of steel components by introducing carbon into their surface layer during carburizing, and then rapidly cooling them to form a hard martensitic structure during hardening. In the carburizing process, components are heated to high temperatures, typically between 870–950°C, in a controlled atmosphere rich in carbon-bearing gases such as carbon monoxide, carbon dioxide, and hydrocarbons. This controlled atmosphere ensures the precise diffusion of carbon into the surface of the steel, enhancing its hardness and durability. Following carburizing, the components are hardened by rapid quenching in oil or water, transforming the carburized layer into a tough martensitic structure.
