Keywords:
Category:
1. Equipment Name: Bell-type Furnace (Sintering Furnace)
2. Applicable products: Sintering of copper‑based heat pipes and annealing heat treatment.
3. Power supply: Three-phase 380 V, 60 kW
4. Operating gas: N2 nitrogen, a 95% N2 + 5% H2 mixed gas
5. Operating temperature: Typically around 650–980°C, with a rated temperature of 980°C.
6. Heating time: From room temperature to 980°C, it takes 90–120 minutes (based on empty‑furnace testing).
7. Installation dimensions: Length 2,300 mm, Width 2,300 mm, Height 3,800 mm
8. Furnace dimensions: Length 1,750 mm, Width 1,560 mm, Height 3,650 mm (designed in upper and lower sections)
9. Furnace hood dimensions: diameter 500 mm, height 1510 mm, thickness 5 mm.
10. Effective volume of the furnace hood: diameter 450 mm, height 1200 mm.
11. Furnace chamber dimensions: inner diameter 600 mm, outer diameter 900 mm, height 1300 mm.
12. Furnace lining: refractory bricks arranged in a stacked configuration with 18 layers of heating elements; the heating elements can be quickly removed.
13. Furnace Chamber Temperature Control: The furnace chamber employs six-zone temperature control, with K-type thermocouples.
14. Furnace temperature control method: The furnace is equipped with six-zone temperature monitoring, using S-type thermocouples.
15. Lifting method: Uses an electric-hydraulic lifting platform, ensuring smooth operation, safety, and a maximum load capacity of 2.0 tonnes.
16. Air inlet and outlet configuration: Air is supplied and exhausted from both sides of the furnace hood, with a central clearance to facilitate horizontal sintering.
17. Gas switching: Automatically switches between N2 nitrogen and mixed gases.
18. Control Box: Integrated, fixed installation on the furnace side.
19. Equipment Rack: Welded square-tube frame with a gray-white baked finish.
