Customizable
Design Standard:
The carbide pressure sintering furnace is a single-chamber, double-door horizontal, cyclic heating structure designed for easy loading and unloading and maintenance. The whole process is controlled automatically with safety interlock. Full load continuous operation is realized with its maximum ability of 300 furnace times/year or 300 working days/year. Adopting graphite element resistance heating (low voltage, high current) with multiple heating units, each unit of temperature is individually controlled ; The whole process is controlled by computer automation, monitoring, tracking, fault self-diagnosis simulation display and record. The process is controlled by PLC and industrial control machine (IPC) to realize the one-key start-up of the whole process, real-time dynamic monitoring, temperature, pressure, vacuum and other parameters saving and reliable alarm interlock.
Equipment color matching: furnace body, voltage transformer, control cabinet and vacuum pump surface is light gray (color code: RAL7035),. Furnace leg, pump stand and support are sky blue (color code: RAL5015). The wire slot is stainless steel, support galvanized. The transformer placement can adjust according to customer's site 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). |
|
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. |
