Specialized heat treatment equipment designed to improve the physical and chemical properties of metal materials and components. Includes furnaces and devices specifically designed for heat treatment processes such as quenching, tempering, annealing, carburizing, and nitriding. Features heat treatment-specific functions including temperature control precision, atmosphere control capabilities, and cooling systems, distinguishing it from simple heating devices or general industrial furnaces. Used in manufacturing processes aimed at improving hardness, stress relief, and microstructure improvement of automotive parts, tools, and mechanical components.
