Surface treatment and anti-corrosion process of large centrifugal induced draft fan

Large induced draft fan plays an important role in industrial production, and the medium temperature of induced draft fan is often high temperature, the temperature from 100-900 ℃ are by, which puts forward higher requirements for the anti-corrosion of the fan, in order to ensure its long-term stable operation and prevent corrosion, the surface treatment and anti-corrosion process is particularly
