control method

Using Yudian program temperature control instrument

1. 50-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 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 temperature of the furnace when the power is turned off.

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

Type B


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

Current limiting function: No matter how to adjust the heating time, the secondary current of our electric furnace after passing through the transformer is limited to 160A, which protects the equipment to a limited extent. No matter how you operate, the equipment will not burn out.

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

Electrical appliances



106 / 16E Simmonk, Germany

Limit switch The furnace door is equipped with a travel switch. When the furnace door is opened, the power will be automatically cut off to prevent the danger of electric shock when it touches the heating element.
warranty period

One year warranty, lifetime technical support

Special Note: 1. Consumable parts such as heating elements, 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. For safety, please place the stove in a ventilated place.

2. In order to improve the service life of the furnace, we recommend that the heating rate should not exceed 10 ℃ / min. The cooling rate does not exceed 5 ° C / min.

3. The furnace has no vacuum tightness, and it is forbidden to pass toxic or explosive gas.

4. It is forbidden to place the material directly on the bottom of the furnace. Please place the material in a special crucible.

5. When heating, do not touch the heating element and thermocouple with the material and crucible.

6. When not in use for a long time, please use the oven again.

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


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)



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
