Abstract: The research and application of functional oxidation resistant coating of cast steel at high temperature were reviewed, including its type, composition and protective mechanism. Such coating is composed of high melting-point materials, such as SiO2, Al2O3 and MgO, low melting-point materials, such as TiO2 and CaO, as basic materials, water glass, borate and aluminium phosphate as binder with some other special functional materials. By comparing various kinds of coating, the protective mechanism of coatings and design fundamental were discussed. How to increase adaptability of coating to different steel and service conditions, to enhance the protective effect, stability and suspension property, to resolve the distribution, adhesion and to ensure the heat conduction are the future research topics.

Key words: coatings, oxidation resistance, decarburization, billet, high temperature protection
