What are the configurations that can be customized for vacuum tube furnaces?

The configuration of vacuum tube furnace can be customized according to the specific needs of customers. The following are some common customizable configurations:

Furnace body size:
Furnace size: The length ranges from tens of centimeters to several meters, and the diameter ranges from a few centimeters to several meters, to meet the needs of experiments or production at different scales. For example, for continuous sintering or heat treatment of materials, a longer furnace is required to meet the residence time of materials in different temperature zones; For small-scale laboratory research, a shorter furnace can be chosen.
Furnace tube size: including parameters such as outer diameter, inner diameter, length, and wall thickness. The length of the furnace tube is generally slightly longer than the length of the furnace to leave space for installing sealing devices, rotating drive devices, etc. The wall thickness needs to be determined based on factors such as furnace tube material, working pressure, and temperature.
Temperature range and heating element:
Working temperature: ranging from a few hundred degrees to 1800 degrees, or even higher, to meet the processing requirements of different materials.
Heating element: optional resistance wire, silicon carbon rod, silicon molybdenum rod, etc. Choose the appropriate heating element according to the working temperature range and equipment requirements.
Temperature zone and temperature control system:
Temperature zone: Supports customization of single temperature zone, dual temperature zone, and multi temperature zone. The length and temperature range of each temperature zone need to be clearly defined to meet the material processing requirements under multiple temperature conditions in the same furnace.
Temperature control system: adopting PID regulation method, multiple temperature rise and fall programs can be set, with a temperature control accuracy of up to ± 1 ℃. Some high-end devices also support intelligent control, such as 50 segment programmable control, as well as functions such as PC remote operation and mobile client cloud operation.
Atmosphere control and vacuum system:
Atmosphere control: The function of introducing different atmospheres (such as inert gases, reducing gases, etc.) can be customized, and gas control equipment such as mass flow meters can be equipped to accurately control the composition and proportion of the atmosphere.
Vacuum system: The size of the connection port should match the selected vacuum equipment such as vacuum pumps to ensure good vacuum sealing and pumping efficiency. Optional medium vacuum or high vacuum system, with a maximum vacuum degree of 1 × 10 ⁻ ³ Pa or lower.
Furnace structure and material:
Furnace structure: There are two common types: vertical and horizontal. The vertical structure occupies a small area and is suitable for places with limited space; The horizontal structure facilitates the entry and operation of materials, and is suitable for large materials or processes that require continuous feeding.
Furnace body material: The inner and outer shells are usually made of double-layer sheet metal structure, with ventilation in the middle to reduce external temperature. The furnace insulation material adopts high-purity alumina fiber, zirconia board and other high-temperature resistant materials to ensure high temperature stability.
Other special configurations:
Rotating design: promotes uniform heating of materials inside the furnace tube, improves heat treatment efficiency and product quality.
Safety protection: equipped with functions such as over temperature protection, thermocouple protection, and leakage protection to ensure the safe operation of the equipment.
Auxiliary equipment: such as crucible tongs, corundum boats, furnace hooks, pipe plugs and other accessories, as well as auxiliary equipment such as vacuum pumps, pressure reducing valves, flow meters, etc., can be selected according to customer needs.
In short, the configuration of a vacuum tube furnace can be fully customized according to the specific needs of customers to meet the processing requirements of different fields and materials. When choosing customized services, it is recommended to have detailed communication with professional manufacturers, clarify your own needs, and understand the performance parameters, prices, delivery time, and other information of the equipment.
