A mesh-belt furnace cannot be quoted from the furnace type name alone.

A mesh-belt furnace is a custom-engineered continuous heat-treatment system, and no fixed price can be given without reference to the workpiece, cycle time and process. The following factors significantly affect the furnace body structure, conveyor system, control configuration and delivery scope.
| Mesh-belt furnace is suited to | Bogie-hearth furnace is suited to | Roller-hearth furnace is suited to |
|---|---|---|
| Batch processing of small parts, standard parts and fasteners | Continuous conveying of plates, bars or fairly regular workpieces | |
| Stable throughput requiring continuous production | Defined line cycle time with high demands on in-furnace conveying stability | |
| Lightweight parts that can be spread across the mesh belt | Workpieces better suited to roller-table support and straight-line conveying | |
| A focus on mesh-belt speed, layer thickness and charging/discharging integration | A focus on furnace roller material, load, drive and roller-table maintenance | |
| Suited to continuous annealing, tempering, quench heating and other batch processes for small parts | Suited to continuous heat-treatment lines for plates, bars, tubes and similar products |
Mesh-belt furnaces are suited to fasteners, small parts, stampings, standard parts and high-volume parts that require continuous heat treatment. Workpiece dimensions, unit weight, layer thickness, belt width, running speed and cooling method all affect the furnace chamber length, the temperature-zone configuration and the stability of continuous production.
Common processes include quenching, tempering, annealing and normalizing. Where continuous quench-and-temper or protective-atmosphere operation is required, the whole line should be evaluated together with the material grade, the heat-treatment curve, the cooling medium, the washing and drying stages and the tempering-section configuration.

The following combines parameters from an authorized, anonymized mesh-belt furnace project with common applications. Throughput, speed, and dimensions apply only to the corresponding workpiece, loading method, and process conditions; they are not fixed model guarantees.
The project used a belt assembly measuring about 2100 × 200 × 50 mm, with an effective working width of about 180 mm, a 950°C rated temperature, throughput of about 60 kg/h, and belt speed of about 10–114 mm/min.
Temperature zones and control configuration are determined around tempering temperature, load thickness, mesh-belt speed and recording requirements.
Furnace chamber length and throughput/cycle time are evaluated based on material, annealing temperature, soak time and cooling method.
Can be assessed as a preliminary project direction; material grade, solution temperature, cooling rate and atmosphere conditions must be confirmed.
The focus is on multi-product changeover, charging/discharging integration, maintenance windows and room for future expansion.
Mesh-belt furnaces are well suited to standard parts, fasteners, hardware, stampings, small metal components and high-volume parts requiring continuous heat treatment. They are especially appropriate for products that are relatively light per piece, dimensionally consistent and can be spread out and conveyed continuously. Selection should be based on workpiece dimensions, unit weight, layer thickness on the belt, required throughput and the intended heat-treatment process.
A mesh-belt furnace can be used for continuous annealing, continuous tempering, quench heating, aging and stress relief. Solution treatment can also be evaluated on a project basis, but it requires careful confirmation of the material grade, temperature schedule, cooling rate, atmosphere conditions and the heat resistance demanded of the belt. We do not recommend specifying a configuration in isolation from the actual workpiece and process.
The price of a mesh-belt furnace is mainly driven by belt width, furnace chamber length, the number of temperature zones, maximum temperature, throughput, belt material, heating method, atmosphere requirements, cooling method, the control system, and integration with charging and discharging. A mesh-belt furnace is typically a custom-engineered unit, so we need the parameters first before we can assess the proposal and price range.
A mesh-belt furnace emphasizes continuous conveying and a steady cycle, which suits high-volume heat treatment of small parts, standard parts and fasteners. A bogie-hearth furnace uses batch charging and is better suited to large, heavy or irregularly shaped workpieces. When choosing between them, compare workpiece weight, charging method, throughput and the on-site loading and unloading conditions.
The mesh-belt furnace is a common continuous heat-treatment furnace type and can be configured on a project basis for continuous feeding, heating, soaking, cooling, tempering, or washing and drying. That said, its continuous-running capability depends on the belt material, drive system, refractory lining, heating system, maintenance windows and on-site management, and should be confirmed against the actual operating conditions.
Temperature uniformity depends on furnace chamber length, zone layout, the arrangement of heating elements or the combustion system, refractory insulation, belt speed, layer thickness, atmosphere circulation and the control system. The target figures should be set during the proposal stage in line with the effective heating zone, process temperature and acceptance criteria; fixed values should not be guaranteed in isolation from the operating conditions.
An assessment can be carried out first. Common upgrade directions for an old mesh-belt furnace include relining the refractory, servicing the belt and drive system, upgrading the heating system, retrofitting zone temperature control, optimizing the cooling section and improving the safety interlocks. Whether a retrofit is worthwhile depends on the condition of the furnace body, the available downtime window, spare-parts availability and the retrofit cost taken together.
We recommend preparing the workpiece material, dimensions and unit weight, the required throughput per hour, the belt width or existing line speed, the maximum temperature, the heat-treatment process, atmosphere requirements, the cooling method, the loading and unloading method, on-site photos and the supporting site conditions.
