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 small high-temperature tube furnace that has passed CE certification. The furnace tube is a 2" diameter corundum tube and the heating element is a silicon carbide rod. The instrument itself has two true sealing flanges (the flange has been
|The main parameters||
|Furnace structure||·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||· Furnace tube: high-purity corundum tube, which can withstand a maximum temperature of 1650℃
· Furnace tube size: 50mmO.D x 40mmI.D x 700mm
·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)
|Vacuum sealed||·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
|Vacuum||·Mechanical vacuum pump: 10-2 torr
·If you want to get a higher vacuum (<10-5 torr or better), you can choose domestic or imported high vacuum unit
|Optional||·Optional flange: hinged flange produced by our company
The standard mechanical vacuum gauge measures in the pressure range of -0.1 to 0.15Mpa
·The anti-corrosion digital vacuum indicator imported by our company has a measuring range of 3.8x105 to 1125 Torr. There is no need for coefficient conversion due to different types of measuring gases
|Temperature Control System||·Contains a YD518P 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 (for YD518P series controller) is used to control the heating curve and export data.
|Heating element||4 1600℃ grade silicon carbide rods|
|Dimensions||Furnace size: 1050 × 300 550mm × (Updated: 2018.8.23 - S)
Furnace size: 150X100X110
|net weight||68 Kg|
|Certification||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.|
|Warranty||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.
|Application note||·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.)
