product description
KBF1400-LF-2 vacuum atmosphere lifting furnace is described in detail:
KBF1400-LF-2 vacuum-atmosphere lifting furnace with silicon carbon rod as the heating element, Using the double-layer shell structure and the Yudian 30-section program temperature control system, Phase shift triggered, SCR controlled, The furnace is made of type 1600 alumina polycrystal fiber material, Double furnace housing with air cooling system, Can quickly lift and lower the temperature, The furnace has the advantages of temperature field equilibrium, low surface temperature, fast lifting temperature rate, energy saving and so on, Easy to take up the materials, Without requiring the crucible tongs to reach into the furnace, Suitable for high-temperature feeding and annealing, It is an ideal product for universities, scientific research institutes, industrial and mining enterprises to do powder sintering, ceramic sintering, glass smelting, high temperature experiment and quality testing.
1.heating element
(1)The thickness D1 of the hot end of the silicon molybdenum rod is 7mm, the 6MM used by the 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 use of hot bending technology, uniform resistance, long service life
(3)The length of Lu cold end is 210mm, the 400X300X300 furnace is 260, the general manufacturer uses 180mm, the cold end long furnace roof temperature is low.
(4)the silicon molybdenum rod surface oxidation amorphous film dense, can better protect the silicon molybdenum rod.
2.Install the air switch and the leakage protector:
When the circuit is overcurrent or leakage, the empty meeting is automatically disconnected.

KBF1400-LF-2 vacuum atmosphere lifting furnace technical parameters:

3.can be connected to the computer
The furnace is equipped with communication interface and software, which can directly control the parameters of the furnace through the computer, and can observe the temperature value of PV and SV on the furnace and the operation of the instrument. The actual heating curve of the furnace will be drawn in real time, and can save the temperature data of each moment, which can be adjusted at any time
4.Furnace
(1)vacuum suction filter molding of high quality high purity alumina polycrystalline fiber curing furnace.
(2)Using Japanese technology to shape.
(3)The spacing and pitch of the resistance wire in the furnace are all arranged according to the optimal thermal technology in Japan, and the thermal field is simulated through the thermal software
(4)With 4 weeks of heating, the temperature field is more balanced
(5)The furnace does not drop powder, the material insulation performance is good, high reflectivity, temperature field balance, resistance to heat rise and cold contraction ability is strong
5.Optional UL certification electrical board (all imported electrical appliances approved by UL certification)
6.Trigger
(1)Phase shift trigger (with soft start and flow limiting function)
(2)Flow limiting function: no matter how the heating rate is set, the secondary current of our electric furnace is always limited to 170A, which effectively protects the equipment. Due to the flow limiting function, the furnace door can be opened at high temperature. If the electric furnace you use needs to limit the heating rate of the furnace (e. g., not 3℃ / min, etc. after 1400℃), a non-current limiting trigger is used. If the heating rate is set correctly or the heating rate is too fast, the current will be very large and the equipment will trip or burn out.
(3)Soft start function: the current will slowly increase when the machine is started, and the impact on the heating element is small, which is conducive to the extension of the life of the heating element
(4)Protection function: if the current exceeds the limit current, the trigger will automatically cut off the trigger function to cut off the current protection electric furnace.
7.UL certified transformer
(1)Transformer cable is pure copper
(2)The transformer sound is small
(3)Transformer temperature and body is low
8.Certification

Seal system: the furnace roof cover and furnace door (welded in other places) are using silicone O-ring extrusion seal, easy to remove, repeatable removal, good air tightness, and can ensure that the 8-hour pressure gauge pointer does not deflection.
The furnace is a three-layer shell structure, there is a layer of gallbladder in the sealing layer, will not be squeezed to the furnace when vacuum.
Advantages of the atmosphere lifting furnace:
1.can be furnace around the furnace, the temperature field is more balanced.
2.it is convenient to take the material, especially at high temperature need to take the material, such as the material dropped out of the furnace after the user took from the tray, so that there will be no radiant heat in the furnace, to avoid scalding people.
3.There are four rod supports around the pallet, and the material is very stable on the pallet.
(Optional) explosion-proof system: the explosion-proof system is composed of solenoid valve, microcomputer, pressure display and transmitter, 24V power supply, AC contactor, etc. The pressure in the furnace is transferred to an electrical signal through the pressure display and the transmitter to the microcomputer, which compares with the set value and then gives the signal to control the AC contactor, so as to control the opening and breaking of the solenoid valve. When the pressure in the furnace is greater than the allowable pressure we set, the solenoid valve immediately opens to play an explosion-proof effect. We installed the air pipe on the solenoid valve, and the user can connect the pipe to discharge the gas outdoors
The explosion-proof system has many advantages:
(1)with usability: when the pressure is greater than the set value, the solenoid valve opens, when the pressure is lower than the set value, the solenoid valve closes, unlike the mechanical riot control, it can not be used once.
(2)The setting value is adjustable: the user can adjust the opening pressure of the solenoid valve through the microcomputer as needed
(3)the explosion-proof point is very sensitive: due to the use of micro computer and electrical signals, the pressure to the explosion-proof point immediately burst.
(4)Explosion-proof system safety: there is no debris flying out when the explosion starts.(If mechanical, glass pieces may fly out)
(5)explosion-proof system stability is good: due to the use of microcomputer and solenoid valve, to our setting point will explode, the user and can test, unlike mechanical can not be tested, to the explosion-proof point will open whether there is also a lot of uncertainty.
