Valid working space | 400mm×400mm×1200mm |
Max design pressure | 10-100bar |
Pressure time | It takes no more than 25 min to reach 58 bar. |
Cooling time (full load) | Cooling time for sintering 1450℃～100℃: 7-8h (water Temperature≤30℃,
55bar≤pressure≤58bar) |
| Max.loading weight | 500kg(The load capacity depends on the product type) |
| Power rating | About 400KVA (The output power can be limited) |
Service life for furnace shell | 20 years |
Operating times for furnace shell | 6000 furnaces |
Max. Design Temperature | 1600℃(while vacuum sintering) |
Max. Working Temperature | 1550℃(vacuum and pressuring) |
| Pumping speed | The vacuum degree can reach 5Pa within 30min after starting the
pump. After reaching 5Pa and then pumping for 60min, the ultimate
vacuum value reaches 1Pa (within a cold, empty and clean furnace
that has been dried before). |
| Leakage rate | ≤3Pa/h (stop the pump group operation and start checking after
testing the limit vacuum (within a cold, empty and clean furnace
that has been dried before). |
Filled with high pressure argon | It adopts intermittent and stable inflation, and the inflation time
can be set. The system accurately matches inflation volume and time
to ensure the inflation. |
| Wax yield rate | ≥98%(10Kg pure paraffin, argon negative pressure dewaxing. Measured
by three times of mean values at most). |
UPS guarantee time | It can power the indicator light and control the furnace during
power outage for more than 80 minutes. |
| Max.heating rate | 8℃/min (the room temperature rises to 1900℃within a vacuum and
empty furnace. 600℃, 1000℃, 1200℃ half-way insulation is allowed). |
Hot zone temperature uniformity | In the process of vacuum and pressure sintering, the temperature
uniformity of pressure (58bar) is 1450℃: high pressure gas is
filled at the maximum allowable speed, and the temperature
fluctuation of thermocouple is ≤±5℃. |
Sintering Area Atmosphere Uniformity | Degreasing forming agent under positive pressure, negative
pressure, sintering uniformity under gas pressure: furnace control
piece (YC40 or YG6 particles) and paraffin forming agent are evenly
distributed on the graphite boat. The buyer shall provide the
furnace control piece and program, and the seller shall confirm. Alnico: test cobalt magnetic field after dewaxing, deviation range:
≤±0.2%; Coercive force: deviation range: ≤± 0.3kA /M. The
uniformity of furnace temperature is the standard of the uniformity
of coercive force. |
