Integrated Gas Pressure Vacuum Dewaxing Metal Sintering Furnace 2200 Degree Celsius

Valid working space(W*H*L)

Design Pressure

Working Pressure

Pressuring time

Less than 20 min. (up to 58 bar, air source pressure is between 80bar-100bar)

≤7h(empty furnace,from 1450℃ cooling down to 100℃, water temperature≤26℃,55 bar≤Ar pressure≤58 bar)

Max.loading weight

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℃.

Sintering zone atmosphere uniformity

UNIFORMITY (Through dewaxing & pressure sintering): same type furnace control piece (YC40 or YG6 medium particles), paraffin, PEG, evenly distributed on the flat boat. Furnace control piece and process provided by the buyer, seller confirms.

Cobalt magnetism: test it after dewaxing, COM: ≤±0.2%;

Coercive force: HC:≤±0.3KA/M, the temperature uniformity in the furnace is mainly based on the test performance of the furnace control plate.
