Summary:The utility model relates to a vermicular cast iron composite material for boiler construction; the key point product performance of the boiler made of rolled steel and grey cast iron is restricted by the defect of the materials, and the boiler performance is low, particularly the high-temperature protection technology of the metallic surface is still in research stage; in order to solve the above technical matters, the utility model provides a function gradient composite material which takes a vermicular cast iron as a basic body layer; an oxidation-resisting alloy oxidizing layer and a ceramic surface protecting layer are arranged on the surface of the function gradient composite material which has the advantages of good heat-proof corrosion performance, anti-thermal fatigue, compactability, air impermeability, small sectional sensitivity and high absorptive rate of radiation; the reliability service performance and the durability of the manufacture boiler are enhanced, which creates condition for enhancing the boiler thermal efficiency.
