KTL1400-1700-1400The three temperature zone tube furnace has three heating zones, which adopt a double-layer shell structure and electronic control temperature instruments. Each heating zone can30Temperature control by segmented program, phase shift trigger, thyristor control. The furnace is made of alumina polycrystalline fiber material, and stainless steel flanges are installed at both ends of the furnace tube. Gas nozzles, valves, and pressure gauges are installed on the stainless steel flanges. When vacuuming, the vacuum degree can reach10-3 PaThe furnace is horizontal, with three temperature zones that can be independently controlled and set to different temperatures. It is easy to use and operate. The furnace has the advantages of temperature field balance, low surface temperature, fast temperature rise and fall rate, and energy saving. It is suitable for universities, research institutes, and industrial and mining enterprises to conduct high-temperature atmosphere sintering, atmosphere reductionCVDIdeal product for experiments and vacuum annealing.

Software control system:The furnace is equipped with communication interfaces and software, which can directly control various parameters of the furnace through a computer and observe the furnace from the computerPVandSVThe actual temperature rise curve of the furnace, including temperature values and instrument operation, will be plotted in real-time by the computer, and the temperature data at each moment can be saved and accessed at any time. (Optional)

Open lid protection system:The furnace is equipped with a travel switch, which automatically cuts off the power when the furnace cover is opened, effectively ensuring the safety of the user.

Sealing system: The double-layer silicone is used between the furnace tube and the flange of the furnaceOThe ring is compressed and sealed, easy to remove, and can be repeatedly removed. It has good air tightness and can ensure12The pointer of the hour pressure gauge does not deflect.

Vacuum system: Can be matchedTW-1.5AVacuum pump and capable of pumping10-1PaVacuum pump or capable of pumping10-4PaGermany imports molecular pumps.

Furnace material: Using alumina fiber furnace material, it does not shed powder, has good insulation performance, high reflectivity, balanced temperature field, and strong resistance to thermal expansion and contraction.

Leakage protection function: The furnace is equipped with a leakage air switch, which automatically cuts off power when the furnace body leaks electricity to ensure safety during use.

Gas supply system: The furnace is equipped with a float flowmeter, and customers can control the gas flow rate through the float flowmeter or proton flowmeter (please refer to the options for details).

flange ：By adopting double ring sealing technology, the atmosphere of the flange is effectively improved. The flange is equipped with various joints, which can be connected to a resistance vacuum gaugeKF25The corrugated tube can be made into a hinged design that is easy to remove.

Flange bracket:The flange is supported by a flange bracket, effectively eliminating the stress caused by the flange on the corundum pipe and extending the service life of the corundum pipe.

KTL1400-1700-1400Vacuum degree of three temperature zone tube furnace:

1）Generally, rough vacuuming is used to expel the gas from the furnace tubeTW-1.5Aimmediately

2）2XZ-2The vacuum pump can pump the vacuum degree of the tube furnace tube to10Paabout

3）VS-0.1The vacuum system can draw the vacuum degree inside the tube of the tube furnace to0.1Pa(Equipped with a resistance vacuum gauge display)

4）VSThe high vacuum system (composed of molecules and mechanical pumps) can draw the vacuum degree inside the tube furnace to10-3 Pa.
