Vacuum-sealed flanges and valves

1.A stainless steel sealing flange and stainless steel needle valve are installed on the top of the furnace body

2.The bottom of the furnace body is equipped with a plug-in valve, a non-mechanical pressure gauge, and a KF25 vacuum interface for connecting a vacuum pump

3. Vacuum degree: The vacuum degree of the mechanical pump can reach below 1Pa. If you want to obtain a higher vacuum degree, you can choose a domestic or imported high vacuum unit. The vacuum degree can reach 10-3Pa.

Optional: The following accessories increase vacuum efficiency

4.KF25 stainless steel bellows, KF25 quick remover clamp

5. Optional anti-corrosion digital vacuum gauge with a measurement range of 3.8x10-5 to 1125Torr. No need for coefficient conversion due to different types of measurement gases

6. At the top of the flange is installed an electromagnet sample hanging device that can withstand a maximum of 1000g. As shown in Figure 1, the sample is hung on the hook through the hanging wire, as shown in Figure 2. Click the control button of the sample hanging device of the electromagnet. The hanging wires fall into the quenching box together, as shown in Figure 3. Before releasing the sample, 5 PSI of argon must be flushed in and the manual flapper valve at the bottom of the furnace tube opened. Figure 4 is the hanging wire

Quenched container

1. A stainless steel box for quenching liquid is fixed at the bottom of the furnace tube

2. A large manual plug valve is installed between the bottom of the furnace tube and the liquid box

warranty period

One year warranty, lifetime technical support

Special tips: 1. Consumable parts such as heating elements, furnace 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.


Precautions

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, and the pressure in the furnace tube must be equal to the atmospheric pressure.

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

8. The sample is fixed on a suspension hook at the bottom of the flange by a high temperature resistant wire. (Remarks: The maximum use temperature of the wire that is standard with the equipment of our company is 1200 degrees. If the customer's use temperature is above 1200 degrees, you can buy our company's special high temperature resistant wire, please consult our company for details)

1.Heating element

(1) The thickness D1 of the hot end of the silicon molybdenum rod is 7mm, 6MM 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) Using hot bending technology, uniform resistance and long service life

(3) Lu cold end length is 210mm, 400X300X300 furnace is 260, general manufacturers use 180mm, cold end long furnace top temperature is low.

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

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

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 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.

4. Adopting 4 weeks heating, the temperature field is more balanced

不掉粉、材料保温性能好、反射率高、温场均衡,抗热涨冷缩能力强 5. The furnace does not drop powder, the material has good thermal insulation performance, high reflectivity, balanced temperature field, strong resistance to thermal expansion and cold shrinkage

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

6.Trigger

VS

Soft-Start Current-Limit Trigger Non-Current-Limit Used by Most Manufacturers

Xiamen Bote Trigger

1. Phase-shift triggering (with soft start and current limit functions)

2. Current limiting function: No matter how you set the heating rate, the secondary current of our electric furnace is always limited to 170A, which effectively protects the equipment. Due to the current limiting function, the furnace door can be opened at high temperatures. If the electric furnace you use needs to limit the heating rate of the furnace during the heating process (for example: it is not allowed to exceed 3 ° C / min after 1400 ° C, etc.), a non-current-limiting trigger is used. If the heating rate is set incorrectly or the heating rate is too fast, the current will be very large and the device will trip or burn out.

3. Soft-start function: The current will increase gradually when starting up, and the impact on the heating element is small, which is beneficial to the extension of the heating element life.

4, protection function: If the current exceeds the limit current, the trigger will automatically cut off the trigger function to cut off the current to protect the electric furnace.

7.UL certified transformer

1.The transformer cable is pure copper
2.Small transformer sound
3. Low temperature of transformer

8, a variety of flanges to choose from (diameter from 25 to 250mm)

                            

Hinged flange (optional) Flange that can be connected to resistance vacuum gauge and KF25 bellows (optional) Water-cooled flange (optional)
