Accurate operation greatly improves the durability of corundum tubes, ceramic tubes, alumina, and other materials

The thermal shock resistance of corundum is relatively poor, and the corundum tube is fragile and vulnerable. However, in order to better extend the service life of the corundum tube and reduce all usage costs, it is recommended to use these methods to make the corundum tube more durable and durable. When setting out for sampling, it is best to be within 200 ℃, and it is best to slowly advance from the edge to the center. The corundum tube is prone to damage and damage during high-temperature sampling. The furnace tube must be kept clean and free from residual impurities that can settle inside the tube, avoiding a series of chemical reactions that can cause cracking and damage to the corundum tube. Placing the test sample in a crucible before placing it in the tube is safer.
The heating and cooling rate during the heat treatment process of a tubular furnace is around 4 ℃ per minute, preferably slower. Sudden cold and heat, as well as susceptibility to damage and fracture, with a temperature not exceeding 1630 ℃ being the best.
Aluminum oxide tube products and industrial ceramic parts are mainly used for continuous temperature measurement of molten steel, thermocouple temperature measurement, various industrial furnaces, and vacuum electric furnaces. The product is suitable for many other industries such as instruments and meters, sintered porcelain teeth, mechanical processing, military industry, and so on.
