Freeze nine inputs before asking for comparable prices: workpieces/loading, hourly output, process time/cycle, effective width/conveying, heating/zones, atmosphere, cooling/post-treatment, controls/automation and acceptance/supply. Two “mesh belt furnace” quotations can otherwise cover entirely different equipment.
One Suneng mesh-belt line proposal lists loading, quench heating, the quench tank, tempering and industrial controls separately. When a supplier says the mesh-belt furnace is included, confirm whether it means the main furnace or this group of equipment, then mark inclusions and exclusions against the project's process route. This example supports scope checking; it does not mean that every mesh-belt line has the same composition.
1. One furnace or a complete line?
The name may refer only to a continuous heating furnace or to a complete treatment line. The furnace may include entry/exit, conveying, heating, controls and necessary atmosphere interfaces. A line may additionally include loading, preheating, quenching/cooling, washing, drying, tempering, discharge, central controls and site interfaces.
This is not a fixed combination. List each stage, inclusion, exclusion and responsibility. A furnace-only price cannot be compared directly with one including quenching, washing, tempering and commissioning.
2. Workpieces and loading determine conveying
Provide grade, maximum/usual size, individual weight and shape, including rolling, jamming, overlap or collision tendencies. Define single-layer or permitted stacked loading, mass per length/area and feeding stability. These affect carrier, effective width, capacity, positioning, stability and maintenance. Belt, chain-plate or roller-supported arrangements require workpiece-specific assessment rather than copying a previous project.
3. Compare hourly output with process time
The same hourly quantity can need different widths, heating lengths and zones when dimensions, weights, loading, residence time and speed differ. Supply normal/peak output, loading pattern, full curve, residence time, continuous-duty schedule and changeovers.
Any capacity agreement also needs test parts, loading, equipment state, continuous-run duration and conforming-output criteria. One figure is not a guarantee for every condition.
4. Width, speed, heating and zones are linked
Effective width depends on loading, spacing, edges and conveying stability. Speed and residence time affect heating lengths and line cycle; increasing speed or furnace length alone cannot resolve all thermal or interface limitations. Sustained temperature, curves, continuous load, utilities and changeovers determine lining, heat source, circulation, zones and maintenance.
5. Atmosphere and downstream treatment change the line
Protective or controlled atmosphere, oxidation or decarburization limits may require seals, medium supply, monitoring, exhaust, alarms and safety interfaces. Configure these for the material, process and site.
Quenching/cooling, washing, drying, tempering, transfer and collection change length, controls, utilities and acceptance. Draw the process route and assign each stage's inputs, outputs and owner.
6. Break automation into testable functions
“Fully automatic” is not a comparable configuration. Specify temperature programs, conveying speed, stage interlocks, alarms, recipes, records, export, supervisory-system interfaces, manual takeover and safe shutdown. State what is included, what the buyer must provide and what remains a future extension. Instrument behaviour, furnace distribution, workpiece temperature and product results need separate criteria.
7. Align acceptance and supply
Compare transport, unloading, lifting, installation, commissioning, training, foundations, utilities, ventilation/emissions, factory checks, cold integration, hot commissioning, loaded tests, documents, spares, warranty and service. Output, temperature, records and interlock tests need defined workpieces, loading, state, duration and criteria. Resolve scope differences before comparing equipment price and subsequent investment.
Nine-input checklist
| Input | Buyer supplies | Supplier explains |
|---|---|---|
| Workpiece/loading | Grade, size, weight, shape and feeding. | Carrier, supports, loading and maintenance basis. |
| Hourly output | Normal/peak rate, shifts and continuous duty. | Capacity conditions and bottlenecks. |
| Process time/cycle | Curve, residence and changeovers. | Length, speed, zones and cycle relationship. |
| Width/conveying | Loading width, spacing, imbalance and stability. | Effective width, operating method and abnormal handling. |
| Heating/zones | Sustained temperature, utilities, load and records. | Lining, heat source, circulation, zones and interfaces. |
| Atmosphere | Target, medium, site and safety conditions. | Seals, supply, monitoring, exhaust and interlocks. |
| Cooling/post-treatment | Quenching/cooling, washing, drying, tempering and collection. | Equipment stages and coordinated cycle. |
| Automation | Recipes, interlocks, alarms, traceability and higher-level interfaces. | Included functions, buyer conditions and extensions. |
| Acceptance/supply | Interfaces, test parts, documents and service needs. | Inclusions, exclusions, methods and owners. |
Adapt these groups to the project rather than treating them as a fixed contract directory.
Suneng's scope
Suneng designs, manufactures and integrates furnace equipment and provides commissioning, retrofit and support. It can clarify custom mesh-belt and continuous-line proposals using agreed workpieces, loading, output, curves, atmosphere, post-treatment, automation, site and acceptance.
