Mesh Belt Low Temperature Tempering Furnace | 50°C – 300°C for Fastener & Spring

Mesh Belt Low Temperature Continuous Tempering Furnace is forced hot air circulation continuous heat treatment equipment with working temperature range 50~300℃. Workpieces are conveyed continuously by stainless steel mesh belt to complete low-temperature stress relieving, hydrogen removal & aging after quenching automatically. Widely used for mass production of fasteners, springs, precision hardware & aluminum parts; can connect with pre-washing machine & mesh belt quenching furnace to form full auto heat treatment line.

1.Conveying System: Chain supported SUS stainless steel mesh belt, driven by variable frequency motor with belt deviation alarm, stable operation & long service life.

2.Furnace Body & Insulation: Welded steel shell + full aluminum silicate fiber lining, outstanding thermal insulation, shell surface temp＜45℃, energy-saving design.

3.Electric Heating System: Zoned Cr20Ni80 nichrome heating tubes, modular external installation for easy maintenance.

4.Hot Air Circulation: Top high-temperature resistant circulation fan + directional air duct, full convection to guarantee uniform temperature inside chamber.

5.Electric Control Cabinet: PLC + multi-segment PID temperature controller, program curve storage & over-temperature auto alarm; optional IoT remote monitoring.

1.Full auto continuous production, minimal labor cost, easy to connect with full production line to raise output greatly;

2.Precise low temp control with full hot air circulation, stable tempering quality & tiny workpiece deformation;

3.Energy-saving fiber lining, stable running power only 40%~50% of rated power, low long-term operation cost;

4.Eco-friendly design without nitrate & salt bath, less oxidation on workpiece surface, clean workshop environment;

5.Optional accessories: nitrogen atmosphere for bright tempering, outlet air cooling unit, full PLC automatic control system.

1.Fastener: screw, nut, spring washer, self-tapping screw (low temp tempering & hydrogen removal after quenching at 150~200℃);

2.Spring parts: compression spring, circlip, disc spring for stress relief & elasticity stabilization;

3.Precision hardware: bearing spare parts, auto spare parts, stamping component stress relieving;

4.Non-ferrous metal: aluminum aging 120~180℃, copper part low-temperature stress relief.
