The hood and flue have been working in high temperature environment for a long time, and the working environment is harsh, especially the heating surface is subjected to sulfur gas corrosion, high temperature oxidation and erosion wear, and it is easy to produce a large number of bamboo-shaped thermal fatigue cracks, hemp on the water-cooled pipe. Points and perforations leak water, which affects the production efficiency of steelmaking.  The role of thermal spraying in fume hood protection is very significant. There are many thermal spraying technology methods, but the arc supersonic spraying developed in recent years is undoubtedly the best process method for fume hood protection. Its advantages are:   1. Low cost and high efficiency;   2. The bonding strength is higher than other spraying;   3. Ceramic powder can be added to the wire to improve erosion resistance.   Based on domestic and foreign experience, we have developed a three-layer composite arc supersonic spray coating. The application in fume hoods and power plant boilers has proved that the service life of both can be extended to more than three years.
