How to choose a corundum tube and an introduction to its characteristics in applications

    Corundum tube It is a very good heat-insulating, fire-resistant and wear-resistant ceramic tube. It is indispensable in various enterprises, but corundum tube There are many types. How to choose the one you need?

　　First, we need to briefly understand corundum tube its function. corundum tube Used for analyzing and dissolving metal and non-metal samples of various sizes in laboratories. It is mostly used in vacuum high-temperature tube furnaces, etc., with excellent high-temperature resistance, high density, thermal stability, acid and alkali resistance, and washing test, etc., and also has good performance.

　   corundum tube It is a very important component in the tube furnace. Because it is made of corundum material, its ability to withstand rapid cooling and heating is very poor, and its service life is very limited. Generally, it is recommended that the temperature rise and fall be kept below 5/minute, and it should be slow. During the cooling process, the cooling curve must be set, and it is not allowed to directly cool naturally from high temperature to room temperature, otherwise the tube is easily cracked, and the temperature at which it is easily cracked is generally 800-1000℃.

Corundum tubes that are not used for a long time need to be baked at around 200-300 degrees for 5-6 hours to corundum tube remove the internal moisture, which helps to extend the service life.

　 Corundum tube It can be used in many fields, and this product is very practical and durable, and there will be no problems even after long-term use. However, due to the construction of such products in batches.

　 Because contractors cannot accurately calculate how many corundum ceramic tubes you need at one time, it is recommended to sign a contract. More refunds and less supplements, in any case, buying one product, or letting the other party provide an excessive amount of corundum ceramic tubes at one time to help us return, can also save more money.

　　 corundum tube Features in application

　 　corundum tube In fact, you can roughly know its characteristics from the name, and it almost inherits all the characteristics of ceramics. It is widely used in our industrial production, so what are its characteristics?

　　First, corundum tube Like ceramics, it is corrosion-resistant, in other words, its chemical properties are very stable, and it is not easy to react with many substances in the air. At the same time, it is very wear-resistant because it contains ceramic materials. Experiments show that its wear resistance is more than ten times that of quenched steel. Because the outside is a steel pipe and the inside is corundum, it has good temperature resistance.

　　The cost is also moderate, because the quality is very light, and of course, not much material is needed. Of course, because it is light in weight, it is very light and easy to install, and there will be no great difficulty. For example, quenching and linking are very convenient.

　 　corundum tube In actual use, the reason why it is welcomed by everyone is simply because it is needed, and there is such market demand. Moreover, in the process of use, there are things that everyone likes, and the functions of the genuine products that are liked by everyone. These excellent performances have brought benefits to everyone.
