Applications: for cemented carbide, precision ceramic, stainless steel, iron-based alloy, copper-based alloy, aluminum products.
Functions: Vacuun dewaxing, H2 dewaxing, vacuum heating, heating with gas mixture(CO2 /CH4/H2), heating flowing gas, rapid cooling.
Part of technical parameters:
Valid working space(W*H*L) | 400mm×400mm×1200mm |
| 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) |
Heating power | 320KVA |
Designd 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 |
Positive pressure, negative pressure release forming agent, pressure integrated sintering uniformity: same type furnace control tablets (YC40 or YG6 medium particles), paraffin wax, PEG forming agent, uniformly distributed on the flat boat. Furnace control tablets and procedures provided by the buyer, The seller confirms. Cobalt magnetism: test cobalt magnetism after dewaxing, deviation range: ≤±0.2%; coercive force: deviation range: ≤±0.3KA/M, the temperature uniformity in the furnace is mainly based on the test performance of the furnace control plate. |
