The KTL1400 tube furnace uses silicon carbon rods as heating elements, adopts a double-layer shell structure and an electronic control temperature instrument, and can perform multi-stage program temperature control, phase shift triggering, and controllable silicon control. The furnace is made of alumina polycrystalline fiber material, and the gas flow rate is controlled by a flow meter. The two ends of the furnace tube are sealed with stainless steel flanges, and gas nozzles, valves, and pressure gauges are installed on the stainless steel flanges. When vacuuming, the vacuum degree can reach 10-3Pa. The furnace is horizontal, easy to use, and easy to operate. It has the advantages of temperature field balance, low surface temperature, fast temperature rise and fall rate, and energy saving. It is an ideal product for universities, research institutes, and industrial and mining enterprises to conduct high-temperature atmosphere sintering, atmosphere reduction, CVD experiments, and vacuum annealing.

(1) The thickness of the hot end of the silicon carbon rod is 14mm, which is 12mm commonly used by manufacturers. The heating end is thick, not easy to bend, and the surface load of the rod is low, resulting in a long service life.
(2) The length of the cold end is 210mm, and generally manufacturers use 180mm. The cold end is long and the furnace top temperature is low.
(3) The amorphous oxide film on the surface of silicon carbide rods is dense, which can effectively protect the carbon rods.

When the circuit experiences overcurrent or leakage, the circuit will automatically disconnect

The actual heating curve of the furnace will be drawn in real time by the computer, and the temperature data at each moment can be saved and retrieved at any time

(1) High quality high-purity alumina polycrystalline fiber solidification furnace formed by vacuum suction filtration.
(2) Adopting Japanese technology for molding.
(3) The furnace material has low heat capacity and low thermal conductivity, resulting in less heat dissipation, good insulation, and high reflectivity. Temperature field equilibrium.
(4) The furnace alumina wire is thin and long, with high temperature resistance and strong resistance to thermal expansion and contraction
(5) The furnace surface is smooth and not prone to powder loss.

Adopting Yudian program temperature control instrument (standard)

1. 30 segment program temperature control intelligent PID regulation.

2. Equipped with over temperature protection and thermocouple breaking protection, the heating circuit of the electric furnace will automatically cut off in case of over temperature or thermocouple breaking (when the temperature of the electric furnace exceeds 1200 degrees or the thermocouple burns out, the AC relay on the main circuit will automatically disconnect, the main circuit will be disconnected, the ON light on the panel will turn off, and the OFF light will turn on, providing limited protection for the electric furnace).

3. Equipped with 485 communication interface (standard when selecting software)

4. It has a power-off protection function, which means that when the furnace is powered on after a power outage, the program does not start rising from the starting temperature, but from the furnace temperature when the power is cut off.

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

1. Generally, TW-1.5A can be used for rough vacuuming and expelling the gas from the furnace tube
2. The 2XZ-2 vacuum pump can pump the vacuum degree of the tube furnace tube to around 10Pa
3. The VS-0.1 vacuum system is capable of pumping the vacuum degree inside the tube furnace to 0.1Pa (and equipped with a resistance vacuum gauge display)
4. The VS high vacuum system (composed of molecular and mechanical pumps) is capable of pumping the vacuum inside the tube furnace to 10-3 Pa

The flange interface can be transformed:

1. In order to increase the pumping rate and achieve higher vacuum requirements. The original hose connector can be replaced with KF-25 interface (both VS-0.1 and VS high vacuum system interfaces are KF25)
2. If used in the gas supply system, the original hose connector can be replaced with a Φ 6.35mm double socket connector
