Engineered to the Process
Furnace chamber length, heating zones, the control curve and cycle time are tailored to the workpiece material, heat-treatment process, heating temperature, soak time and cooling requirements.
Mesh-Belt Heat-Treatment Furnace Series
The roller-supported mesh-belt electric resistance furnace line is built for the continuous annealing, tempering, normalizing, solution treatment, pre-heating and drying of standard parts, hardware, bearing components, stampings, powder-metallurgy parts and small-to-medium workpieces. Based on workpiece material, dimensions, layer thickness, throughput and cycle time, mesh-belt width, roller-support arrangement and site conditions, Suneng delivers custom-engineered continuous heat-treatment equipment.
Furnace chamber length, heating zones, the control curve and cycle time are tailored to the workpiece material, heat-treatment process, heating temperature, soak time and cooling requirements.
Mesh-belt width, roller-support arrangement, line speed and level of automation are matched to workpiece dimensions, unit weight, batch throughput, loading/unloading method and shop-floor layout.
The roller supports provide continuous support to the mesh belt, reducing belt sag and tracking deviation. This suits continuous conveying, batch production and heat-treatment lines with medium-to-long furnace chambers.
Multi-zone temperature control, stable conveying and a well-designed heat-circulation system offer room to improve heating consistency across the workpiece; actual results depend on the specific operating conditions.
Energy-efficiency optimization can be assessed based on the furnace insulation structure, heating zoning, heat-circulation system and continuous-operation regime.
A roller / mesh-belt electric resistance furnace line cannot be quoted from the equipment name alone. The figure depends on the workpiece material, dimensions, layer thickness, throughput cycle time, mesh-belt width, roller structure, furnace chamber length, supporting process sections and site conditions, and is ultimately governed by the technical proposal agreed by both parties.
| Roller-Supported Mesh-Belt Furnace Suits | Standard Mesh-Belt Furnace Suits | Roller-Hearth Furnace Suits |
|---|---|---|
| Continuous heat-treatment lines with medium-to-long furnace chambers | Small parts, standard parts, fasteners | Plate, bar, tube or regularly shaped workpieces |
| Applications needing roller support for the running mesh belt | Lighter individual parts that can be laid out on the mesh belt | Workpieces better suited to direct support and conveying on a roller table |
| Stable production batches with long continuous run times | Relatively moderate chamber length and load | Higher demands on in-furnace conveying stability and load-bearing method |
| Requirements for mesh-belt running stability and conveying support | Stable batches with continuous loading and unloading | Suited to continuous heat-treatment lines |
| Suited to continuous processing of standard parts, hardware, stampings, powder-metallurgy parts, etc. | Suited to continuous annealing, tempering and quench heating of small parts | Suited to continuous annealing, solution treatment and tempering of regularly shaped workpieces |
The roller-supported mesh-belt furnace line is suited to small parts, fasteners, standard parts, stampings, powder-metallurgy parts and batch continuous heat-treatment parts. Workpiece dimensions, unit weight, the way parts are stacked and the batch cycle affect belt width, roller structure, chamber length and the loading/unloading method, all of which must be confirmed against the on-site line conditions.
This type of line is commonly used for continuous quenching, tempering, normalizing, annealing and batch continuous heat treatment. Whether to include a quench tank, tempering section, washing and drying or a protective atmosphere should be evaluated together with the material grade, heat-treatment curve, cooling method and surface-quality requirements.

The roller-supported mesh-belt furnace line is well suited to standard parts, hardware components, bearing parts, stampings, powder-metallurgy parts and small-to-medium batch workpieces. Whether a roller-supported mesh-belt configuration is appropriate depends on the workpiece dimensions, unit weight, layer thickness, heat-treatment process and continuous-running cycle.
A roller-supported mesh-belt furnace uses rollers to support and guide the belt, which makes it better suited to longer furnace chambers, extended continuous operation or relatively stable charging. A conventional mesh-belt furnace has a simpler structure and is typically used for small, light-load parts and continuous heat treatment in chambers of moderate length.
Yes. Depending on the project, a roller-supported mesh-belt furnace can be used for continuous annealing, tempering, normalizing, solution treatment, preheating and drying. Each process has different requirements for maximum temperature, holding time, cooling method, belt speed, number of temperature zones and auxiliary sections, all of which should be confirmed item by item during the proposal stage.
Price is mainly influenced by belt width, effective chamber length, heating-zone length, roller structure, number of temperature zones, maximum temperature, belt material, hourly throughput, cooling method, whether a quench tank, washing, drying or tempering section is included, and the scope of the control system and on-site installation and commissioning.
Belt width is usually determined by the workpiece geometry, the way parts are laid out, the effective charging width and the charge load; running speed is related to heating time, holding time, cooling method, throughput cycle and heating-zone length. Both must be calculated together with the number of temperature zones, the roller structure and the upstream and downstream processes.
Temperature uniformity depends on the effective heating zone, belt speed, charge thickness, temperature-zone layout, heating elements, hot-air circulation design, refractory-lining insulation, the temperature-measurement method and the acceptance criteria. Specific figures cannot be promised independently of the project configuration and should be confirmed against the operating conditions, test conditions and contract terms.
We can first assess the condition of the refractory lining, belt and roller wear, heating elements, drive system, temperature-control system, insulation and sealing, the cooling section and energy-consumption data. Whether a retrofit or overhaul is worthwhile depends on the equipment age, the available shutdown window, spare-parts availability and the process targets after the upgrade.
We recommend preparing the workpiece material, type, dimensions, unit weight, layer thickness, hourly throughput, maximum temperature, normal working temperature, heat-treatment process, cooling method, whether a washing/drying or tempering section is required, the loading and unloading method, and the site-layout information.
