400mm×400mm×1200mm |
Design Pressure |
60bar |
Working Pressure |
58bar |
Pressuring time |
Less than 20 min. (up to 58 bar, air source pressure is between 80bar-100bar) |
Cooling speed |
≤7h(empty furnace,from 1450℃ cooling down to 100℃, water temperature≤26℃,55 bar≤Ar pressure≤58 bar) |
Max.loading weight |
500Kg(The load capacity depends on the product type) |

320KVA |
Design service life of the furnace shell |
20 years |
Max. Design Temp. |
1600℃(under vacuum sintering) |
Max. Working Temp. |
1550℃(under vacuum and gas preesure condition) |
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). |
High pressure Ar gas filling |
It adopts intermittent and stable inflation, and the inflation time can be set. The system accurately matches the relationship between inflation volume and time to ensure the followability of inflation. |
Wax Collection 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 ( full load, half-way insulation is allowed) |
Hot zone temp. 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℃. |
