The range of a TF tube furnace, specifically a high-temperature tube furnace, typically spans from room temperature up to 1700°C or even 1800°C, depending on the model and configuration. These furnaces are designed for high-temperature applications such as sintering, annealing, and heat treatment, and are widely used in research labs, production facilities, and technical ceramics manufacturing. The horizontal orientation of tube furnaces allows for continuous processing of long samples, and they are equipped with heating elements like resistance wires or graphite elements to achieve uniform high temperatures. Alumina tubes are commonly used for high-temperature operations, though they must be carefully selected to avoid thermal shock.
Key Points Explained:
-
Temperature Range:
- The operating temperature of a high-temperature tube furnace typically ranges from room temperature up to 1700°C or 1800°C, depending on the specific model and heating elements used.
