In order to improve the service life of high purity corundum furnace tube and reduce the loss caused by damage caused by improper use, the following suggestions are put forward for users' reference: 1. The maximum use temperature of high purity corundum furnace tube should not exceed 1700℃, and the long-term use temperature should be below 1650℃. 2. The high temperature area of high purity corundum furnace tube should avoid mixing with impurities, especially metal debris and non-metallic mineral raw materials containing K2O, Na2O, CaO, SiO2, etc., otherwise it is easy to form low temperature eutectic and corundum tube damaged..........

1. After the sample is placed, the two heat insulation plugs should be placed in the correct position. Select a small pressure reducer and connect them as shown in the figure below; 2. Adjust the pressure regulator to the relative pressure ≦0.05Mpa. Open the intake valve and observe the absolute pressure gauge at the intake end. Adjust the flow, observe bubbles, and protect the atmosphere normally.

When cracks occur after ≧5mm, the shrinkage of fiber in non-refractory layer is generally caused by the erosion of volatiles of sintered materials (strong acid and alkali, or lead vapor and vanadium pentaoxide). In actual use cases, some components added in zirconia products of sintered materials and volatiles of dyeing agent of customers are easy to cause cracking of fiber products when caking ...
