The temperature range, control accuracy, and usage precautions of the experimental vertical tube furnace are key factors affecting the experimental results. Let's take a detailed look below!
1. Temperature range
The temperature range of experimental vertical tube furnaces usually varies depending on the model and purpose. The common temperature ranges are as follows:
Low temperature range: Some vertical tube furnaces can reach lower temperatures, such as 200-1000 ℃, which is suitable for experiments with low temperature requirements.
Medium temperature range: The working temperature of many vertical tube furnaces is between 1000 ℃ and 1200 ℃, which is a commonly used temperature range in laboratories and is suitable for sintering, annealing, and other treatments of various materials.
High temperature range: The highest temperature of high-end vertical tube furnaces can reach 1600 ℃ or even higher, such as 1700 ℃, which is suitable for special experiments that require high temperature treatment.
2. Temperature control accuracy
The temperature control accuracy of the experimental vertical tube furnace is also an important indicator for measuring its performance. Generally speaking, high-precision vertical tube furnaces can ensure the accuracy and reproducibility of experimental results. For example, the temperature control accuracy of a vertical tube furnace can reach ± 1 ℃, which is important for experiments that require precise temperature control.
3. Factors and precautions affecting temperature
Heating element: The quality of the heating element directly affects the heating speed and temperature uniformity of the furnace. High quality heating elements not only have fast heating speed and uniform heating, but also have a long service life.
Furnace tube material: The selection of furnace tube material is also important. For example, corundum furnace tubes have characteristics such as high temperature resistance and corrosion resistance, making them suitable for high temperature and corrosive environments.
Temperature control system: The accuracy of the temperature control system determines the repeatability of the experiment. PID controller is a common high-precision temperature control system that can achieve precise temperature control.
Operating standards: When using a vertical tube furnace, it is necessary to strictly follow the operating standards. For example, during the heating process, the heating rate should be controlled to avoid furnace tube rupture due to thermal expansion and contraction; After the experiment is completed, the furnace temperature should be naturally cooled to room temperature before stopping ventilation and opening the furnace.
In general, the temperature of the experimental vertical tube furnace ranges from 200-1700 ℃. It is recommended to communicate with relevant technical personnel about the parameters you want before choosing, so as to customize a vertical tube furnace that is more suitable for your experiment!Click to learn more Vertical tube furnaces!
