Continuous Mesh Belt Furnace – Automatic Heat Treatment Line for High-Volume Fastener Production
Our continuous mesh belt furnace with protective atmosphere is designed for quenching, tempering, carburizing and bright annealing of bolts, screws and rivets. Stable temperature control, uniform metallurgical performance and 24-hour continuous operation for fastener factories.
Continuous mesh belt furnace is an automatic continuous heat treatment furnace, widely used as the core thermal processing equipment matching cold heading machines and thread rolling machines in fastener production lines. It uses heat-resistant stainless steel mesh belt to convey workpieces steadily through preheating, heating, quenching, washing, tempering and cooling zones. Under controlled protective atmosphere, it completes quenching, tempering, carburizing, carbonitriding, bright annealing and stress relief in one continuous flow, avoiding the batch inconsistency of box-type batch furnaces.
The whole line adopts PLC intelligent control system. Mesh belt speed, furnace temperature, atmosphere flow and quenching liquid parameters can be precisely adjusted according to material and strength grade, such as Grade 8.8, 10.9, 12.9 high-strength bolts. The sealed furnace structure reduces atmosphere consumption and oxidation, keeping clean surface and stable hardness of finished fasteners. It can process carbon steel, alloy steel, stainless steel, spring steel and copper parts.
Core Advantages of Continuous Mesh Belt Furnace
- Consistent heat treatment quality: Every workpiece gets the same heating and holding time, small hardness deviation, low reject rate, stable metallurgical structure.
- 24h continuous automatic production: Can connect inline with cold forming and thread rolling equipment, greatly improving throughput and cutting labor cost.
- Atmosphere protection & less decarburization: Controlled protective atmosphere prevents surface oxidation and decarburization, meets high-strength fastener standards.
- Energy saving design: Optimized heat insulation structure, less repeated heating loss compared with intermittent batch furnaces.
- Flexible process adjustment: Supports quenching, tempering, carburizing, bright annealing and stress relief for different product requirements.
- Easy operation and maintenance: Modular structure, convenient mesh belt replacement and routine inspection.
Main Application Industries
- Fastener manufacturing: High-strength bolts, nuts, screws, self-drilling screws, rivets, studs, anchor bolts
- Automotive & new energy: Chassis fasteners, engine bolts, battery connecting hardware
- Hardware & spring industry: Small stamped parts, springs, pins, bearing rollers

- General machinery: Small precision shafts, connection components
Many fastener manufacturers upgrade their heat treatment workshop with continuous mesh belt furnace lines to meet higher strength standard and stable batch quality. When selecting a mesh belt furnace, buyers need to confirm belt width, temperature range, processing capacity, atmosphere type and whether it needs a full quenching & tempering integrated line.
Our continuous mesh belt heat treatment lines are built for heavy-duty long-run operation. We supply complete furnace systems, spare mesh belts, atmosphere accessories, installation guidance and after-sales technical support for global fastener manufacturers. It is a perfect match for multi-station cold heading machines and thread rolling machines to form a full fastener production line.
