Detailed technical parameters






3.5 KW



Furnace tube

Quartz tube: 60/80/100 * 1500mm (pipe diameter is optional)

Put a furnace plug on each side. The furnace plug can block the heat radiation in the center of the furnace tube. It must be placed in the correct position of the furnace before heating.

control method

Use Yudian program temperature control instrument (standard)

1. 30-segment program temperature control intelligent PID adjustment.

2. With over-temperature protection, the electric furnace heating circuit will be automatically cut off when the temperature is too high or the temperature is broken. ON, the ON light on the panel is off, the OFF light is on, and the electric furnace is limitedly protected).

3. With 485 communication interface (standard with optional software)

4. It has a power failure protection function, that is, when the furnace is powered on after the power is turned off, the program does not start from the initial temperature, but starts from the furnace temperature when the power is turned off.

5.The meter has the function of temperature self-tuning

(Replacement of imported instruments requires additional payment, purchase)

FP93 temperature control instrument (Japan Shiden) Eurometer instrument touch screen instrument

Furnace material

1. High-quality high-purity alumina polycrystalline fiber curing furnace formed by vacuum suction filtration.

2. Molded by Japanese technology.

3.The spacing and pitch of the resistance wires in the furnace are all arranged according to the best thermal technology in Japan, and the temperature field is simulated by thermal software.

Degree of vacuum

1.Single- stage pump TW-1.5A 2.Double-stage pump 2XZ-2 3.VS -0.1 vacuum system

4. VS high vacuum system 5. Constant pressure pump 6. British PCG550 (INFICON) capacitance vacuum gauge

1. Generally use a rough vacuum to drive the gas out of the furnace tube: TW-1.5A single-stage pump can be used.

2. The two-stage pump 2XZ-2 vacuum pump can draw the vacuum degree of the tube furnace tube to about 10Pa.

3. The VS-0.1 vacuum system can draw the vacuum degree in the tube furnace tube to 0.1Pa (with a resistance vacuum gauge display).

4, VS high vacuum system (this system is composed of molecular and mechanical pump) can draw the vacuum degree in the tube furnace tube to 10 -3 Pa.

5. Constant pressure pump (This system can control the pressure in the tube at -100.0KPa ~ 100.0KPa).

6. British (INFICON) capacitance vacuum gauge (measurement range 3.8x10-5 -1125 Torr, can detect various gases, including mixed gas, accurate measurement, good repeatability, optional anticorrosion type PCG554)

One year warranty, lifetime technical support

Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not under warranty

2. Damage caused by the use of corrosive gases and acid gases is not covered by the warranty.


1. The air pressure in the furnace tube cannot be higher than 0.02MPa

2. Due to the high internal pressure of the gas cylinder, when introducing gas into the furnace tube, a pressure reducing valve must be installed on the gas cylinder. In order to ensure safety, it is recommended to use a pressure lower than 0.02 MPa.

3. When the furnace tube used is corundum tube, when the furnace temperature is higher than 1500 ℃, the furnace tube cannot be in a vacuum state.

4. The gas flow entering the furnace tube needs to be less than 200SCCM to avoid the impact of the cold air flow on the hot furnace tube

5. For the experiment of sample heating, it is not recommended to close the suction valve and inlet valve of the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you must always pay attention to the indication of the pressure gauge. If the pressure is greater than 0.02MPa, you must immediately open the exhaust valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.)

6. Don't use graphite crucibles in alumina tubes

7. MoSi 2 heating element must not be used at low temperature (400 ℃ -700 ℃) for a long time, otherwise the heating element may be damaged

   1.Swedish Kanthal A1 resistance wire

Kanthal A1 raw silk domestic resistance wire hearth VS imported resistance wire hearth

(1), the surface temperature can reach 1420

(2) The surface is stainless steel (very bright, pay attention when customers identify it), will not rust, and will not drop slag even if it is used for a long time.

(3), Kanthal resistance wire data download

(4) Kanthal resistance wire website: www.kanthal.com

(5), resistance balance, temperature field balance is good

Fe-Cr-Al Alloy doped by Mo resistance wire produced by Shougang used by most manufacturers Kanthal A1 resistance wire has uniform resistance and balanced heat generation

Sometimes the resistance is unbalanced, part of the heat is large and part of the heat is small.

2. Installed air switch and leakage protector:

When the circuit is over-current or leakage, the meeting will be disconnected automatically.

3.Can connect with computer

The furnace is equipped with a communication interface and software, which can directly control various parameters of the furnace through a computer, and can observe the PV and SV temperature values on the furnace and the operation of the instrument from the computer. The actual heating curve of the furnace will be drawn by the computer in real time And can save the temperature data at each moment, you can call up at any time
