condition) |
Maximum working temperature | 1600℃ (Under vacuum and pressurization condition) |
| Maximum design pressure | 60bar |
| Maximum working pressure | 58bar |
Pumping speed |
The vacuum degree can reach 5Pa within 30min after starting the
pump.The ultimate vacuum value reaches 1Pa after reaching 5Pa and
pumping for 30min (after drying, cold, empty, dry). |
Leakage rate |
≤3Pa/h (stop the pump group operation and start the test after the
limit vacuum is measured after the oven, .Empty furnace, clean,
cold state, within 3 hours average value). |
Full furnace loading cooling time
|
When the inner furnace fully load materials,the cooling time of
sintering temperature from 1450℃ to 100℃ is ≤6h(water
temperature≤30℃,95bar≤pressure≤98bar) |
Filling high pressure argon | Intermittent stable charging is adopted, charging time can be
set.The system accurately matches the relationship between charging
amount and time to ensure the following of charging. |
Wax collect rate |
≥98%(10Kg pure paraffin, argon negative pressure dewaxing.Maximum
three mean values). |
Pressurization time |
The time of pressurization to 98Bar is ≤15min, which can be set
(the gas source pressure is stable within the range of 120-130bar). |
Uninterrupted power supply guarantee time |
Power the indicator light and control the furnace during power off
for more than 80 minutes. |
Heating up speed | 8℃/min (In full furnace condition, the intermediate temperature
section is allowed to hold). |
Warranty period
The warranty period of the equipment is 12 months, which starts
from the date of installation and debugging of the supplier.
Equipment failure happens, after-sales service personnel shall give
solutions within 2 hours, after receiving the buyer's notification
. If it is need to go to the site for treatment , operators
dispatched by seller should arrive at the site within 48 hours
after go aboard. In case of emergency,operators should arrive at
the site within 48 hours after go aboard, and continue to make
repairs until the fault is removed and the equipment returns to
normal.
