The widespread use of graphite rotor also lets you have a lot of problems for the maintenance of graphite rotor. Many customers will consult us about the oxidation resistance of graphite rotor. Today, we will talk together about the oxidation resistance of graphite rotor.
After oxidation resistance treatment of graphite rotor, in the process of purification and degassing, the surface of the aluminum alloy in the box is covered with nitrogen, so that the graphite rotor is exposed in the aluminum alloy liquid part of the inert gas, to prevent high temperature oxidation, and the service life of the graphite rotor after oxidation, is about five times that of ordinary products.
According to the needs of different industries for different graphite, we choose special materials for customers. After special treatment of anti-oxidation production line, the oxidation resistance can effectively extend the service life of graphite processing products, so as to improve the cost performance of products. When the graphite rotor is immersed in the aluminum liquid before, we should preheat the graphite rotor about 100mm above the liquid level for 5 to 10 minutes, which can effectively avoid the impact of acute cooling on the material.
