This system is primarily designed for shallow carburizing, carbonitriding, and bright hardening of small mechanical components such as bearings, chains, pins, fasteners, and other similar parts. It is ideal for applications requiring precise surface treatment and uniform heat distribution. The system consists of several key components, including the feeding mechanism, heating furnace, quenching tank, washing machine, and tempering furnace. Each part is engineered to work in harmony, ensuring smooth operation and high-quality results throughout the entire process. The heating furnace is designed with advanced structural features to enhance performance and efficiency. First, it uses radiant tubes for double-sided heating, significantly improving heating speed and temperature uniformity. Second, it is lined with lightweight, non-porous full fiber insulation, which saves approximately 30% more energy compared to traditional refractory brick lining. Third, the heat-resistant steel mesh belt is driven by rotating rollers, reducing wear and extending the service life of the conveyor system. Fourth, critical control components are imported, ensuring higher reliability and stability of the entire system. Fifth, a safety alarm system and mechanical interlocking device have been added to enhance operational safety. Finally, the system includes a fully Chinese-language human-machine interface that displays all equipment statuses and allows users to program and adjust various process parameters easily. The quenching tank is equipped with a variable frequency-controlled oil agitator, which helps minimize workpiece distortion during the quenching process. It also features a high-capacity air-cooled heat exchanger for improved cooling efficiency and equipment safety. The closed design of the tank reduces oxidation and decarburization of the treated parts. Additionally, an oil curtain system is used to prevent fumes from entering the heating chamber, maintaining a cleaner and safer working environment. The washing machine utilizes a two-tank system with dual-liquid separation and automatic liquid level monitoring and refilling. A specialized oil-water separator and rotating spray nozzles ensure effective cleaning. After washing, the parts are transferred to an electric drying room for thorough drying. The tempering furnace is designed with cluster-type electric heating elements that are durable and easy to maintain. The mesh belt runs on a flat rail system, increasing its longevity. Exhaust pipes are installed to manage waste gas and oil vapors, reducing environmental impact and improving product quality. Lastly, the furnace is equipped with a digital PID temperature controller, providing precise temperature regulation for consistent and reliable results.
