Vacuum hot press furnace technical data

Model: ZT-25-20Y

Structural characteristics:

1, Water-cooled electrodes patent application in the device has been approved, the patent name: A vacuum furnace with low voltage high current water-cooled electrodes, patent No.: ZL 2007 2 0069725.1, a large-current electrical connection device, No.: ZL 2007 2 0066936.X.

2、When sintering with pressure, the device has the features of automatic booster pressure, automatic stabilize pressure holding pressure. Adopting reliable imported pressure regulator, equipped with speed regulator valve to adjust the speed of pressurizing, also with the features of small pressure fluctuations (≤ ± 0.1 MPa), displacement precision is up to 0.02mm, the digital signal output, strong anti-jamming .

3、 Adopting  controllable silicon pressure regulator + high current transformer, configured with PID function digital instrument program, with the function of over-temperature alarm , transformers interlock protection manual / automatic control. The control panel is equipped with current, voltage, temperature, vacuum, hydraulic, electrical interlock sound light alarms, gauges switches. Electrical control Cabinet is made according to Rittal standard. It is easy to operate, with temperature high accuracy.

4、Using our self-developed tungsten tungsten-rhenium tube thermocouple, Adopting imported ultra-high temperature insulation material, the thermocouple can be measured directly up to 2000 ℃, can be used for long-time at 1950 ℃ high temperature environment, not easy to break even, long using- life, high temperature measurement accuracy (up to ± 1 ℃ temperature measurement error). It completely solve the conventional infrared temperature measurement instrument’s inaccuracy, easy interference other defects.
