Hanging wire

Equipped with three sets of 0.3mm thick Ni-Cr-Al wire suspension wires, which can withstand temperatures up to 1100 ℃

Optional suspension wire that can withstand higher temperatures

Molybdenum wire: up to 1700 ℃

Platinum wire: withstand temperature up to 1600 ℃

The hanging wire can pass through the flange, and if the positive pressure is maintained in the furnace tube, the crystal can be grown in an atmosphere protected environment

For oxygen sensitive materials, samples can be packaged in small quartz tubes

Motor and control

Using stepper motor system

• 6 "L x 4" W touch screen to control DC motor rotation

• Up and down speed can be set to 3 programs

• Speed range: 1-500 nm / s (adjustable), accuracy: +/- 0.05%

• Total moving stroke: 800mm

• Motor power: 50W

Purchase:

Using servo motor system

(The pulling speed is more uniform and stable, improving the quality of single crystal growth)

• 6 "L x 4" W touch screen to control servo motor rotation

• Up and down speed can be set to 3 programs

• Speed range: 1-500 nm / s (adjustable), accuracy: +/- 0.05%

• Total moving stroke: 800mm

• Motor power: 50W

Heating element

Silicon Carbon Rod

control method

Adopt Japanese conductive FP93 intelligent program temperature control instrument (standard)

1, 40-segment program temperature control intelligent PID adjustment.

2. With over-temperature protection. The electric furnace heating circuit is automatically cut off when the temperature is over-temperature or when the electric couple is cut off. 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 temperature of the furnace when the power is turned off.

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

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.

Cover opening safety protection system

The furnace body is equipped with an air switch and a fuse. When the current exceeds the rated current of the circuit breaker, the empty meeting automatically trips to protect the electric furnace effectively.

warranty period

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.Heating element

(1) The thickness d of the hot end of the silicon carbon rod is 14mm, 12MM adopted by general manufacturers, the heating end is thick, not easy to bend, the surface load of the rod is low, and the service life is long.

(2) The length of the cold end is 135mm and the length of the hot end is 140mm.

(3) The oxidized amorphous film on the surface of the silicon carbon rod is dense, which can better protect the carbon rod.

2. Installed air switch and leakage protector:

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

,

3. Can be connected to a computer (optional)

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

Furnace

Imported hearth vs domestic hearth  

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

2. Molded by Japanese technology.

3. The furnace material has low heat capacity and low thermal conductivity, which results in less heat dissipation, good thermal insulation and high reflectivity. Temperature field equilibrium.

抗热涨冷缩能力强。 4. Furnace alumina wire is thin and long, high temperature resistance, strong resistance to thermal expansion and contraction.

掉粉。 5. The surface of the furnace is smooth and easy to drop powder.

5. Optional UL certified electrical board (all imported electrical appliances that passed UL certification)

6, certification
