VRHP vacuum rapid hot pressing furnace for preparation of dense compound materials

Product Description
Introduction of vacuum rapid heated pressing furnace:

CY-1700X-RHP4 is a Vacuum Rapid Heated Pressing Furnace (VRHP or RHP) designed for making dense pallets under vacuum or the protective gas environment. A 15 kW temperature controllable induction heater is integrated into the system, which provides sufficient power for rapidly heating the graphite pressing die up to 1700ºC. The Induction coil is built inside of stainless steel vacuum chamber. An electric hydraulic press is inserted from the bottom of the chamber, providing up to 5 tons pressing force.


Technical parameter of vacuum rapid heated pressing furnace:

Max. Pressure

5 metric tons (10 MPa on pressure gauge).

Hydraulic Electrical Presser

  • Piston diameter: 60 mm.
  • Vertical move distance: 35 mm.
  • Automatic pressure controller

Induction Heater

  • Working voltage: 208 - 240 VAC, 50/60 Hz, three phase (380V three phase available upon request)
  • Working current: 40 A (with a 60 A breaker).
  • Maximum input power: 15 kW.
  • Output frequency: 30 ~ 80 kHz.
  • Duty cycle: 80%.
  • Max. Working Temperature: 1600℃ max duration time: < 30 min.
  • Ultimate Temperature: 1700℃<1 min. (This might cause damage of thermocouple)
  • Air cooling: fan.
  • Protection: water pressure monitoring, high-temperature protection, and overpower protection.

Temperature Controller

  • Working voltage: 208 ~ 240 VAC, single phase.
  • Precision digital temperature controller with automatic PID tuning.
  • Temperature profile that contains maximum 30 programmable segments to control heating, dwelling, and cooling.
  • Overheating and thermocouple failure protection.
  • Temperature accuracy: ± 3℃.
  • B-type thermocouple.
  • Continuous working temperature range: 1000 ~1600℃.
  • lower temperature range (300 - 600℃) is available upon request.
  • Maximum heating rate in vacuum (only for 0.5" inner diameter graphite pressing die; without any thermal block): 
    • 4℃/s ( 4 mins 50 seconds from room temperature to 1200℃)  
    • 2 ℃/s ( 5min 40 seconds from 1200 to 1300℃)
    • 1.5℃/s ( 6min 46 seconds from 1300 to 1400℃)
    • 1.2℃/s ( 8mins 10 seconds from 1400 to 1500℃)
    • 1℃/s ( 9mins 50 seconds from 1500 to 1600℃)
  • Experimental cooling rate in vacuum:
    • 3.5℃/s (~ 2 mins 20 seconds from 1600 to 1200℃)
    • 1.1℃/s (~ 8 mins 10 seconds from 1200 to 800℃)
    • 0.4℃/s (~ 21 mins 25 seconds from 800 to 500℃)
    • 0.16℃/s (~ 37 mins 15 seconds from 500 to 350℃)
    • 0.06℃/s (~ 104 mins 20 seconds from 350 to 150℃)

Processing chamber & Sealing Flange

  • Stainless steel vacuum sealed chamber: 260 × 230 × 320 mm (OD × ID × L).
  • Flanges on both ends of the chamber. Flanges have a tunnel for cooling water.
  • Equipped with a KF-25D vacuum port, pressure gauge, 1/4" gas inlet port with the stainless steel needle valve.
  • The upper flange can be lifted by raising the lead screw which provides the easy access to retrieve the graphite die.
  • Requires at least 55 liters per minute water flow.
  • Vacuum level: up to 10-5 Torr by our molecular pumping station ( turbo pumping system pump) or 7.5 mTorr by a mechanical pump. 10-7 torr turbopump system is available upon request
  • Vacuum pumped is not included.

High-Temperature Graphite Pressing Die Set 

  • Two built-in graphite supporting rods with Max pressure 50 Mpa
  • One set of 0.5" (inner diameter) graphite die are included for immediate use.
  • Made of high purity graphite by HIP processing, Max. Load from the hydraulic press is dependent on die 's ID
    • 0.5"ID: Max. 0.5T (sample pressure 50 Mpa )
    • 1.0 ID: Max. 3T (sample pressure 50 Mpa, which is optional)
  • The graphite pressing die is fragile and consumable. We also provide customized die sets upon customer request at extra cost.
  • Mica spacers are used to adjust the height of die sets and insulate heat. You can order spares at CYKY.
  • Note: The maximum pressure range of graphite dies will vary depending on the inner diameter of the die. For example, the graphite dies with an inner diameter of 0.5" can withstand 0.6 metric tons. For the graphite die with an inner diameter of 1" can withstand 3 metric tons.
  • If use high-quality SiC dies, the pressure can reach 100 MPa.
