In a continuous hardening furnace, workpieces are loaded onto a conveyor belt at the entry end and travel through multiple temperature-controlled zones. The heating zone raises the material to the austenitizing temperature (typically 800-950°C for steel). The soak zone ensures uniform temperature penetration to the core of each component. Upon exiting the furnace, parts are immediately transferred to an integrated quench tank (oil, water, or polymer) for rapid cooling to achieve the desired martensitic structure. The continuous flow design eliminates batch-to-batch variation, ensuring every component receives identical thermal treatment. Advanced atmosphere control systems maintain precise carbon potential for carburizing applications.
