MIM Vacuum Sintering Furnace For Stainless Steel Product
Performance In Increasing Density And Eliminating Pores
Design standards:
The vacuum debinding sintering integrated furnace is a single
chamber and double door horizontal and periodic heating
structure,which is designed for easy handling and maintenance, the
whole process is controlled automatically.It can realize full load
continuous operation, 300 furnace times/year or 300 working
days/year.It uses graphite element resistance heating (low voltage,
high current) .In addition, there are multiple heating units, each
of which controls the temperature separately.It equipped with fully
automatic control function and safety interlock function.The whole
process is automatically controlled, monitored, tracked and
recorded by computer.The PLC, industrial computer (PC) control to
realize the whole process of one-key start, real-time dynamic
monitoring, computer will save temperature, pressure, vacuum and
other parameters ,alarm interlocking is safe and reliable.
General equipment requirements:
It is mainly used for vacuum sintering, vacuum cooling and rapid
cooling of MIM stainless steel materials.It can meet the strict
requirements for the uniformity of furnace temperature and
atmosphere in the sintering process, and the furnace body structure
design is advanced and reasonable, which is convenient for
operation and maintenance.The main supporting components (control
components, sensors, graphite heating element, thermocouple, main
control valve, vacuum pump, etc.) have the international advanced
level, can adapt to the long-term, stable, reliable mass production
requirements.At the same time, the equipment meets the national
requirements of energy conservation and environmental protection.
Technical parameters of equipment
Valid working zone size(W*H*L) | 400mm×400mm×1800mm |
| Max.loading weight | 1000kg(The load is depends on the product type) |
| Temperature | 1600℃(Design maximum temperature) |
| 1550℃(Actual working temperature) |
| 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). |
| Cooling speed | ≤7h(full loaded,from 1450℃ cooling down to 100℃,water
temperature≤26℃,2bar≤water pressure≤3bar) |
| Cooling mode | It's equipped with rapid cooling fan that can cooling together with
furnace. |
| Max.heating rate | 8℃/min (in the case of vacuum and empty furnace, the room
temperature rises to 1450℃, 600℃, 1000℃, 1200℃ half-way insulation
is allowed). |
UPS guarantee time | Power the indicator light and control the furnace during power off
for more than 80 minutes. |
