Company Statement" Zhengzhou KJ Technology Co., Ltd. " belongs to the international business department of KJ Group. Starting today, the company will continue the international business contract signed or currently being performed by " Zhengzhou Kejia Furnace Co., Ltd. " See details >>
KJ-1500X is a single temperature zone open type tube furnace, which can set 30 steps of temperature rise and fall program, and has broken couple and overheat protection. The temperature control accuracy is up to +/- 1°C, and the maximum temperature of the
|The main parameters
|·Maximum temperature: 1500℃ (< 30min)
·Working temperature: 1400℃
·Recommended heating rate: below 1400℃≤10℃/min; above 1400℃≤5℃/min
·Length of heating zone: 390mm
·Maximum power: 6 KW
·Voltage: AC220V 50Hz (need 50 A air switch)
|·Double-layer shell structure with air cooling system
·The furnace uses high-purity polycrystalline alumina fiber to minimize energy loss
·The surface of the inner furnace is coated with 1750 degrees high temperature alumina coating imported from the United States, which can improve the reflectivity and heating efficiency of the equipment, and also extend the service life of the instrument
|· Furnace tube material: corundum tube
· Furnace tube size: (standard configuration) 60 O.D x 50 I.D x 1000mm L
· Furnace tube size: (optional) 80 O.D x 70 I.D x 1000mm L
·In order to prevent the loss of heat in the form of heat radiation, the instrument is equipped with alumina pipe plug (the pipe plug must be put into the furnace tube before heating)
|·Contains a pair of stainless steel vacuum flanges (mechanical pressure gauge and stainless steel globe valve have been installed on it)
·Optional: In order to obtain a higher vacuum degree faster, it is recommended to use KF25 stainless steel flange, stainless steel bellows and digital vacuum indicator
|·Mechanical vacuum pump: 10-2 torr
·Molecular pump: 10-5 torr
|·Optional flange: hinged flange
The standard mechanical vacuum gauge measures in the pressure range of -0.1 to 0.15Mpa
·Anticorrosive digital vacuum indicator, its measuring range is 3.8x105 to 1125 Torr. No need for coefficient conversion due to different gas types
|Temperature Control System
|·Contains a temperature controller
·PID automatic temperature control system
·Intelligent 30-segment programmable control
·Built-in overheat protection and thermocouple failure alarm
·Temperature control accuracy: ±1℃
·Default DB9 PC communication connection port
·Passed MET certification
Optional computer temperature control software is used to control the heating curve and export data.
|·16 1500ºC grade silicon carbide rods (diameter 14mm. x hot end length 150 x length 350mm)
|All electrical components (>24V) have passed UL/MET/CSA/CE certification. If the customer pays the certification fee, the company guarantees that a single device has passed the German TUV certification or CAS certification.
|One year warranty and lifetime technical support.
Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included.
2. Damage caused by the use of corrosive and acid gases is not covered by the warranty.
|·The air pressure in the furnace tube cannot be higher than 0.02MPa
·Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when the gas is fed into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company's pressure reducing valve is 0.01MPa-0.1MPa. It will be more precise and safe to use
·For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
·The flow of gas should be limited to <200 SCCM (or 200ml/min)
