產品詳情

OTF-1200X-HPR-III-80 is a high-pressure rocking tube furnace with three heating zones. The processing tube is made of a Ni-based superalloy. It is designed for heat treatment materials under both high positive pressure with inert gas. The furnace can be heated up to a max. 1100℃at 2.5 bar pressure (or 900℃at 80 bars). It is designed for melting alloy or compound which is easy to evaporate under atmosphere.SPECIFICATIONS

Working Gases	、Inert gas or oxygen 、No hydrogen or any flammable gas is allowed
Heating Rate	、0 – 200 °C: ≤ 10 °C/min 、200 – 700 °C: ≤ 6 °C/min 、700 – 900 °C: ≤ 3 °C/min 、900 – 1100 °C: ≤ 1 °C/min
Cooling Rate	、1100 – 800 °C: ≤ 5 °C/min ?800 – 200 °C: ≤ 10 °C/min ?200 – 0 °C: free cooling
Heating Zone	、Three heating zones: 150 mm + 150 mm + 150 mm 、Total heating zone length： 450 mm 、Constant temp. zone: 280 mm ±1°C
Heating Element	、Fe-Cr-Al Alloy doped by Mo
Thermocouple	、ThreeOmega K-typethermocouples (OD 3 mm) in the furnace
Temperature Control	、Three precision digital temperature controller with 30 programmable segments and +/- 1 oC accuracy 、Safety protection of over-temperature and broken thermocouples are integrated 、PC control software is available at extra cost 、Eurotherm precision temperature controller with +/-0.1℃accuracy is available upon request at the extra cost.
Control Unit	、Control panel is separated from the furnace for safe operation 、Temperature, pressure, and gas flow rate are controlled via the touch screen panel.
Process Vessel	、Made of Nickel-based superalloy 、Vessel Size: OD 60xID 52xL1200 (mm) 、Working gasses: O2 and inert gasses such as N2, Ar, and He 、In or der to melt the alloy or compound which contains the element that is evaporated easily, you may put the sample into a graphite or BN tube with a screw cap as Pic. below the middle ( ( the crucible is available upon request ) 、To fix the sample tube in position during the swing, two ceramic or stainless steel rod with the thermal block is built in the flanges ( see picture right below ) 、Warning:Never put the sample inside the tube directly without crucible or isolated foil to avoid sample react with tube alloy. 、Attention: Processing tube is a consumable part. Please click the photo below to order a replacement or a spare one
Pressure Sensor and Valve	、Pressure gauge with range of 0 – 25 MPa and over-pressure alarm is installed (downstream side) 、Pressure control valve with a working range of 0.2 – 15 MPa is installed (the upstream side with 1/4" BSPP venting port) 、If the measured pressure reaches the high-pressurealarm value, the pressure control valve will be opened until the pressure drops 0.2 MPa (2 bars) below the alarm value 、The manual pressure relief valve is installed for manual pressure control and relief (the downstream side with 1/4" BSPP gas outlet port)
High-pressure relief valve	、Safety pressure relief valve is recommended (the upstream side with 1/4" NPT venting port) 、Please info us your application temperature and we will pre-set the release pressure for you. For example, you need to heat to 800C, the Max working pressure should be 140 bars, we will pre-set the relief valve to 140 bars.
Flange and Fitting	、A pair of 63 mm CF type flanges are included. Please use atorque wrench(optional, not included) to avoid over tightening the flange bolts. 、2 pieces ofcopper O-rings(99 mm ODx82 mm IDx2.2 mm thickness) are included. Please order extra copper O-ring as consumable parts 、A pair of cooling fans are included for air cooling the flanges 、One mobile cart with installation holes isincludedfor easy setup and immediate use
Dimension
Optional Parts(with extra cost)	、Please order heavy-duty rotary vane vacuum pump (7.8 CFM, 240 L/min) –EQ-YTP-50for low vacuum operation (Pic #1) 、If high vacuum operation is needed, please consider the turbomolecular vacuum pump station–EQ-PV-HVS2(Photo #2) 、Gas flow control system is available upon request (Photo #3) 、Please use a torque wrench(optional, not included) to avoid over tightening the flange bolts (Photo #4) 、To measure the electric properties of thermoelectric ceramics under high pressure amp; high- temperature, please order alumina fixture and high-pressureelectrical feedthrough (10 MPa max) with the furnace at extra cost (Photo #5 amp; #6) 12 3 4 5
Operation Instruction
Safety Notes	、Ni-based superalloy (Waspaloy or equivalent) is a reliable material which can be used under high temperature and high pressure. It has excellent ductility and tensile properties. Only creep deformation happens under overpressure, and cracks are usually formed at the center of the tube to release the pressure. Brittle fracture and tube explosion will not happen. Left pics shows Ni-based Superalloy processing tube under overpressure test 、DO NOT overtighten the flange screws as this may cause permanent damage to the flange or screws. Please refer tothe instructionabout proper torque for installing CF flange bolts. We recommend you to use a torque wrench to tighten the screws with the flange 、DO NOT operate the furnace at a temperature/pressureabove the safety limit that STR- recommends 、Extreme caution should be exercised while operating within the vicinity of the high- pressurefurnace. The operator should NEVER stand in front of the flanges, gasinlet/outlet, or the pressure relief valve while the tube is pressure loaded! NEVER face on the gasinlet/outletand the pressure relief valve to avoid injury from high pressure, hot gas discharge 、Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure for safe operation. Please click here to learn how to install the gas regulator. 、For the use with flammable, toxic or corrosive gasses, you must contact STR-engineering group for the consultation to know all the prerequisites and precautionary measures
