Preparation of Anti-Oxidation Coating on Billet Heating for Silicon Steel
Abstract:
Based on the perspective of the linear expansion coefficient, an anti-oxidation coating on billet heating for silicon steel was prepared. The anti-oxidation coating can be used at 1400oC and it has good property of automatic pelling off, and the oxidation burning loss was decreased by 80.65%. The microstructure of the coating was observed by scanning electron microscope. The results indicate that the high-temperature anti-oxidation mechanism of the coating on the surface of steel billet is cavity clogged by molten slag, and the service life of anti-oxidation coating is relied on the resistance to permeation and erosion of molten slag.
