Product Description 1700oC CVD Vacuum Tube FurnaceOverall overview of the equipment:Main uses: ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, special materials, building materials, universities, research institutes, industrial and mining enterprises to do powder roasting, ceramic sintering, high temperature experiments, material processing, quality universities, research institutes Industrial and mining enterprises do high temperature atmosphere sintering, atmosphere reduction, CVD experiments, vacuum annealing and so on.This furnace uses silicon molybdenum rod as heating element, double-layer shell structure and 31-stage program temperature control system, phase shift triggering, thyristor control, furnace high quality high purity alumina fiber, vacuum forming fiber poly light board material . A double furnace structure is used. The furnace has the advantages of temperature field balance, low surface temperature, fast temperature rise and fall, and energy saving.Adopting international advanced technology, the high-performance, high-energy-saving new type developed by ourselves adopts energy-saving ceramic fiber material double-layer structure, which can reduce the external temperature to normal temperature and make the inner cavity temperature distribution uniform.

The double-furnace structure patent is a patented feature that not only heats up quickly, but also has durability and long-term use without collapse.Insulation MaterialsHigh-quality alumina multi-fiber insulation material, insulation layer is 170mm.shellThe furnace shell is made of steel plate and profile welded, and the outer casing is equipped with a removable protective plate. The protective plate is electrostatically sprayed and painted. Fine workmanship and beautiful appearance.Energy saving performanceLight weight, fast heating, energy saving of more than 50%, saving time and effort.Part two:Electric CabinetControl methodControl mode: using automatic control system, from the room temperature to the set temperature setting program, can automatically run. System silicon controlled, temperature control system modular design, simple structure, easy maintenance. Adopt yudian electric meter, imported silicon controlled, can be programmed 30 segments, multi-segment power limit function, multi-group PID parameter self-setting function, can set the constant temperature and insulation curve freely, no interference switching function, the meter has temperature correction and compensation function. Through the interconnection of software and computer, it can realize the remote control, real-time tracking, history record, output report and other functions of single or multiple electric furnaces. The paperless recording device can be installed to realize data storage and output. Overtemperature alarm and power off, leakage protectionInstrument controlTemperature control program YudianNumber of segments of the programming curve30 sections adjustable, can reduce the unnecessary trouble caused by artificial setting.Temperature measuring element and temperature rangeB thermocouple, temperature range 0-1700 ° C, thermocouple close proximity (contact) tube outer wall, can reduce the external temperature to normal temperature and make the inner cavity temperature distribution even.Heating rate1oC/h-10oC/min, adjustableDigital displayMeasurement temperature, set temperature double display, heating power light column displayControl characteristicsModular structure of control system, long life design equipment key part, simple and reliable process, good stability, high precision.Part three: Evaporation systemEvaporation systemThere are three steam heaters, each of which has a volume of 10L and is equipped with programmed temperature control function. The range of temperature control is from room temperature to 200oC. K-type thermocouple is used to measure the temperature.The whole container tank and vaporization pipeline are made of 316 corrosion resistant materials, equipped with air pressure valve and air pressure gauge to manually control the intake air.
