50600 Roller-Type Mesh Belt Heat Treatment Furnace for Fastener and Screw

50600 Roller-Type Mesh Belt Heat Treatment Furnace for Fastener and Screw 

In today’s fastener industry, precision heat treatment is crucial for achieving superior hardness, wear resistance, and strength. The roller-type mesh belt heat treatment furnace production line offers a fully automated and energy-efficient solution for quenching and tempering fasteners, including drywall screws, self-tapping screws, bolts, and nuts. Designed for continuous production under a controlled atmosphere, this furnace system ensures uniform heating, stable quality, and minimal oxidation.

High-Efficiency Continuous Furnace Line

The mesh belt furnace integrates feeding, cleaning, heating, quenching, oil cooling, post-cleaning, tempering, and discharging

into one streamlined process. The quenching furnace operates under a nitrogen–methanol or endogas protective atmosphere,

effectively preventing surface decarburization and ensuring bright, clean fasteners. With multi-zone temperature control and circulating fans,

the furnace achieves uniform temperature distribution and consistent metallurgical performance.

Technical Parameters of Mesh Belt Heat Treatment Furnace

Stable Quenching and Tempering Performance

The oil quenching system includes efficient agitation and cooling to maintain a consistent quenching rate, preventing deformation and ensuring hardness uniformity. Following quenching, components are cleaned and transferred to the tempering furnace, which relieves stress and stabilizes the final mechanical properties. Every stage is automatically controlled and monitored, minimizing human error and ensuring product consistency.

Energy Efficiency and Environmental Control

This continuous mesh belt furnace is built with advanced insulation, waste heat recovery, and optional oil mist filtration systems. Frequency-controlled fans and pumps reduce power consumption, aligning with modern standards for energy-efficient and eco-friendly heat treatment.

Applications and Advantages

Ideal for fastener and screw manufacturers, the system offers:

• Continuous automatic operation for high throughput

• Precise temperature and carbon control

• Uniform quenching and tempering results

• Bright, oxidation-free surface finish

• Low maintenance and labor requirements

Conclusion

The roller-type mesh belt heat treatment furnace combines automation, reliability, and precision engineering to deliver consistent, high-quality fastener products. For manufacturers seeking advanced fastener heat treatment solutions, this furnace line provides an efficient and sustainable path toward better performance, productivity, and energy savings.
