The reason why high alumina ceramic tubes have become the preferred pipe material for high-temperature furnace industry
In the field of high-temperature furnace industry, high alumina ceramic tubes stand out as the preferred pipe material due to their unique properties, mainly based on the following advantages.
1. Excellent high temperature resistance: High alumina ceramic tubes contain a large amount of alumina components, giving them a very high melting point, typically able to withstand high temperatures of 1600 ℃ or even higher. In the long-term high-temperature working environment of the high-temperature furnace, it will not soften, deform or even melt like ordinary metal pipes, and can always maintain a stable shape and structure to ensure the normal operation of the high-temperature furnace.
2. Good chemical stability: During the operation of the high-temperature furnace, the internal chemicals may react with the pipes. High alumina ceramic tubes have stable chemical properties and excellent corrosion resistance to most acids, bases, salts, and other chemical substances. Even under harsh conditions of high temperature and chemical corrosion, it can be used for a long time without being corroded or damaged, greatly extending the service life of the high-temperature furnace and reducing the cost and time consumption caused by frequent replacement of pipes.
3. Low thermal conductivity: High alumina ceramic tubes has a low thermal conductivity, which is crucial in high-temperature furnaces. Low thermal conductivity means that heat is not easily transferred out through ceramic tubes, which can effectively reduce the heat loss inside the high-temperature furnace, improve energy utilization efficiency, and reduce energy consumption costs. At the same time, good insulation performance can also ensure that the external temperature of the high-temperature furnace is not too high, avoiding burns to operators and improving operational safety.
4. High strength and wear resistance: High alumina ceramic tubes have high hardness and strength, and can maintain structural integrity and are not easily damaged in situations such as material erosion and mechanical collision that may exist in high-temperature furnaces. Its wear resistance also makes its surface less susceptible to wear during long-term use, thus maintaining good performance.
5. Accurate dimensional accuracy and stability: In the design and manufacturing of high-temperature furnaces, the dimensional accuracy of pipes is crucial. High alumina ceramic tubes can ensure precise dimensional tolerances during the production process and have minimal dimensional changes in high-temperature environments, which helps with the precise installation and stable operation of high-temperature furnaces, ensuring the performance and reliability of the entire system.
