Continuous pusher-type furnace

Equipment Overview: The continuous pusher-type automatic production line, with its unique design, ingenious construction, stable and reliable performance, and remarkable energy-saving effects, is widely used for large-scale, continuous heat treatments of gears, bearings, and other components. Main Applications: This equipment is suitable for large-scale gas carburizing and carbon-nitrogen co-diffusion, quenching, annealing, normalizing, isothermal normalizing, and other heat treatment processes for parts. Equipment Features: ◆ The bottom-feed feeding method promotes energy efficiency and reduces medium consumption, while also helping to stabilize the carbon potential within the furnace. ◆ The controlled-atmosphere carburizing furnace adopts an independent structure, separated from other zones. An intermediate isolation door is installed between the inner and outer chambers, allowing independent control of temperature and atmosphere. ◆ The heating zone and cooling/diffusion zone of the carburizing furnace are equipped with independent isolation doors that connect to adjacent zones. A motor-driven mechanism lifts and lowers the furnace doors, and a chain-breakage alarm device is integrated into the isolation door system. Once the chain breaks, an alarm is triggered, and the equipment immediately stops operating, thereby preventing damage to other components in case of a malfunction. ◆ The automatic quenching mechanism is semi-enclosed, featuring a dual-station, sealed, submersible transfer system. A small amount of nitrogen gas can be introduced to ensure that the parts complete the entire quenching process without exposure to air. The quenching chamber does not require opening, thus avoiding contact between furnace gases and air when the chamber door is opened and preventing fluctuations in furnace gas pressure. ◆ Temperature controllers, carbon potential controllers, oxygen probes, PLCs, recorders, pneumatic components, low-voltage electrical equipment, and various instruments all utilize world-renowned brands, ensuring the overall stability and reliability of the equipment. ◆ The equipment’s operational process is displayed via animation, making all automatic conditions and process parameters visually accessible. It features a comprehensive material tray movement tracking system and can be monitored and controlled automatically throughout the entire production process through a central computer control system or an operator console (including a multifunctional human-machine interface). All faults are accompanied by alarms and detailed annotations, and remote fault diagnosis and maintenance are also supported. ◆ With advanced technology, excellent stability and durability, and minimal auxiliary facilities required, this equipment offers significant cost advantages in terms of electricity consumption, gas consumption, maintenance costs, and auxiliary facility expenses. ◆ The equipment boasts a high degree of automation; apart from loading and unloading, all other processes are fully automated and controlled. Technical Parameters: The continuous pusher-type furnace is available in both double-pusher and single-pusher configurations. Depending on product processing requirements and production capacity, customized equipment models of different specifications can be provided (standard material trays: 750x750 mm or 650x650 mm).
