Mesh Belt Quenching & Tempering Furnace — Core Heat Treatment Equipment for Fastener Production

Core Advantages of Our Mesh Belt Heat Treatment Furnace

1. Stable & Precise Temperature Control System

   The furnace adopts multi-zone independent temperature control, with high-precision thermocouples and intelligent PID temperature controllers. The temperature difference inside the furnace cavity is controlled within ±5℃, ensuring every batch of bolts, nuts and screws obtains consistent hardness and uniform metallographic structure, effectively avoiding product cracking, soft spots and performance instability.
2. Continuous Automatic Feeding & Discharging Structure

   Equipped with high temperature resistant stainless steel mesh belt and variable frequency speed regulation motor, the feeding speed can be adjusted freely according to different workpiece sizes and heat treatment process requirements. The whole process from feeding, heating, quenching oil cooling to tempering and discharging is fully automatic, greatly reducing manual operation and improving production continuity.
3. Energy Saving & Low Operating Cost

   The furnace cavity is filled with multi-layer high-density heat preservation refractory materials, which greatly reduces heat loss. The heating system adopts energy-saving heating elements, with low power consumption and high thermal efficiency. Compared with traditional box furnaces, the continuous mesh belt furnace can save more than 30% of energy consumption during mass continuous production.
4. Wide Processing Compatibility

   Our heat treatment furnace is applicable to all kinds of standard and non-standard fasteners, including hex bolts, self-tapping screws, lock nuts, spring washers and stamped small hardware. It can process carbon steel, alloy steel and low alloy ductile iron workpieces, completing quenching, high temperature tempering, stress relief and annealing processes.
