Heavy Load & Large Components Roller Hearth Furnace
Engineered for continuous thermal processing of heavy, long, or dense workpieces. Driven ceramic or heat-resistant alloy rollers convey heavy loads through isolated temperature zones without structural sagging or mechanical distortion.
- Driven Ceramic/Alloy Rollers: High-torque continuous drive supports heavy billets, tubes, and forgings up to several tons per hour.
- Multi-Zone Thermal Isolation: Independent PID control zones enable precise heating, soaking, and cooling thermal profiles.
- Protective Atmosphere Integration: Positive-pressure gas locks prevent oxidation and maintain purity during continuous feeding.
Medium & Small Components Mesh Belt Furnace
Optimized for continuous sintering, bright annealing, stress relieving, and quenching of small-to-medium parts. Woven high-temperature alloy wire belts ensure smooth, uniform component transport.
- Smooth Wire Mesh Conveyance: Prevents part collision and surface damage on high-precision stampings, fasteners, and gears.
- Automatic Belt Tensioning: Eliminates thermal expansion slack, reducing mechanical strain and extending belt service life.
- Rapid Quench Tank Coupling: Direct drop-discharge into oil or water quench tanks enables high-speed continuous hardening.
Powder Metallurgy & MIM Continuous Sintering Line
Integrated multi-stage debinding and ultra-high-temperature sintering solutions purpose-built for powder metallurgy (PM) structural parts and metal injection molding (MIM) continuous production.
- Integrated Debinding Zones: Thermal/solvent binder extraction zones seamlessly precede high-temperature sintering.

Selecting the Optimal Continuous Conveyance System
Selecting between continuous thermal processing systems requires evaluating workpiece weight, required ramp-and-soak thermal profiles, atmospheric purity demands, and target production volume. Whether client workloads demand heavy-duty ceramic roller drives or ultra-smooth mesh belt transport, Haitem Furnace custom-engineers continuous conveyance mechanisms to fit exact material profiles and production layouts, fully backed by our manufacturing capabilities.
A continuous roller hearth furnace excels when handling uniform, heavy-duty parts, such as seamless steel pipes, automotive axles, and large structural forgings. By utilizing ceramic or heat-resistant alloy rollers with external driving mechanisms, friction is minimized, preventing conveyor belt deformation and thermal elongation issues under heavy loads. Multi-zone thermal isolation walls ensure tight temperature boundaries, allowing precise heating, soaking, and controlled cooling within a single continuous footprint.
In contrast, a mesh belt furnace provides high adaptability for small-to-medium parts like high-strength bolts, automotive stampings, and precision gears. The continuous woven alloy belt moves uniformly through gas curtains and heating zones, ensuring every individual component experiences identical thermal histories. Integrated tension-control systems mitigate thermal stress on the belt, delivering long service lifetimes and minimal maintenance downtime.
For specialized advanced manufacturing, a fully integrated continuous sintering line bridges debinding and high-temperature sintering into one automated workflow. Designed primarily for powder metallurgy (PM) structural parts and metal injection molding (MIM) components, these production lines feature high-purity hydrogen atmosphere purge zones, binder burn-off exhaust channels, and ultra-high-temperature heating elements to achieve target component density and metallurgical integrity.
