Continuous controlled atmosphere mesh belt type heat treatment furnace

This continuous controlled-atmosphere mesh-belt heat-treatment furnace is suitable for various types of fasteners, including screws, nuts, bolts and other small hardware components. Equipped with a complete intelligent fully-automatic control system, it realizes automatic temperature regulation, automatic carbon-potential control and automatic mesh-belt speed adjustment with closed-loop adjustment of all process parameters. The whole production line supports automatic continuous production, greatly reducing manual intervention and realizing low-manpower operation. It can stably perform gas carburizing, carbonitriding, bright quenching, annealing and tempering. Multi-zone independent PID temperature control ensures stable furnace atmosphere, precisely controls case depth, surface and core hardness, and prevents workpiece oxidation and decarburization. It is ideal for mass continuous heat-treatment production of fasteners with high process consistency and reliable operation.
