Compared with traditional "flame-water cooling" heating, it has the advantages of high efficiency, cleanness, easy operation, safety and pollution-free, and therefore has great application in the industrial field. Broad application prospects; compared with pyrotechnic leveling, induction heating leveling has fast temperature rise, accurate and controllable heat input, and mechanized operation, which can reduce 80% of leveling workload, significantly improve leveling quality, and improve the operator's working environment. ; Eliminates safety hazards such as harmful smoke produced by flame heating, easy to burn skin, flammable and explosive.
