Project Background
Before a new material or process goes into production, it has to be proven in a test furnace that reproduces production conditions at small scale. Shaanxi Chengda Industrial Furnace Manufacturing Co., Ltd. builds industrial heat treatment and test furnace lines that bridge laboratory research and full-scale production.
Case: 100kg Test Furnace for Lanzhou Fangda Carbon
Lanzhou Fangda Carbon New Materials Co., Ltd. required a 100kg test electric furnace capable of simulating high-temperature melting and heat treatment conditions for carbon and new material research. Chengda delivered the unit in a disciplined sequence:
- Design and machining - furnace body, electrode system and water-cooled components machined and purchased parts consolidated
- Factory assembly and debugging - mechanical assembly, hydraulic testing and electrical verification in Chengda's workshop
- Water pressure testing - all water-cooled circuits pressure tested and documented before shipment
- Site foundation preparation - foundation drawings and interface checks issued to the customer
- Delivery - furnace body, conductive arms, spare parts and parts cases packed separately for safe transport
- Hot commissioning - Chengda engineers completed overnight start-up and debugging on site until the furnace reached stable operation
Equipment Characteristics
| Item | Specification |
|---|---|
| Rated charge weight | 100 kg per heat |
| Heating method | Electric arc / resistance heating |
| Electrode system | Adjustable holder with conductive arm |
| Cooling | Water-cooled body and covers with pressure test records |
| Control | Programmable power and temperature control with data recording |
Production Heat Treatment Lines
Beyond test furnaces, Chengda supplies industrial heat treatment production lines for annealing, normalising, quenching and tempering duties, including continuous line layouts with charging and discharging mechanisms, temperature zoning and atmosphere control. These lines are engineered around the customer's product mix, cycle time and plant layout.
Delivered Value
The test furnace allows the customer to qualify new raw materials and process recipes without interrupting production furnaces. Because Chengda also builds production-scale equipment, the test results scale up directly - the same electrode configuration, power densities and cooling philosophy are used on both.
Documentation Handover
Delivery included foundation interface drawings, assembly drawings, water pressure test records, spare parts lists and operating instructions, so the customer's laboratory team can run and maintain the unit independently.
Why a Test Furnace Pays Back
A test furnace lets a materials company trial new recipes, reductants and temperature profiles without risking a production furnace. Because the unit is designed by the same team that builds production equipment, results scale up directly rather than requiring a second round of process development.
