product description
KBF1700-HV high vacuum tube furnace detailed introduction:
Tubular furnace with silicon molybdenum rod for heating elements, using double shell structure and yu electric temperature control instrument, can 30 program temperature control, phase shift trigger, silicon control, furnace using alumina polycrystalline fiber material, furnace tube both ends can stainless steel flange sealing, stainless steel flange installed with nozzle, valve and pressure gauge, vacuum can reach 10-3 Pa, the furnace has temperature equilibrium, the low surface temperature, fast temperature rate, energy saving, is universities, research institutes, industrial and mining enterprises to do high temperature atmosphere sintering, atmosphere reduction, CVD experiment, vacuum annealing with ideal products.
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 oxidized amorphous film is dense, which 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.
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 instrument from the computer. 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)Using 4 weeks of heating makes the temperature field 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 with UL certification)
6.Trigger
(1)Phase shift trigger (with soft start and flow limiting function)
(2)Current limiting function: no matter how to adjust the heating time, the secondary current of our electric furnace after the transformer is limited to 170A, with limited protection of the equipment. Non-limiting limiting, if the heating rate is set correctly or too fast
At low temperature, the current is 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
