Abstract: In order to solve the problem of serious high-temperature corrosion and wear of boiler water-cooled wall tubes un der the working conditions of deep peak regulation and coal blending of thermal power units, the protective effect of highfrequency induction cladding Ni60 alloy coating on boiler water-cooled wall tubes was studied, and the cladding process parameters were optimized through simulation analysis. The ANSYS finite element model was used, combined with transient thermal analys is and static structure analysis, to strdy the effects of different heat source moving speeds, heating power and cladding thickness on the temperature field, stress field and deformation of the cladding layer were studied. The results show that,with the acceleration of the moving speed of the heat source, the overall temperature of the model gradually decreases, and the residual stress and m aximum deformation also decrease. The cladding temperature increases linearly with the increase of heating power. When the thickness of the cladding layer increases, the maximum deformation decreases slightly, and the stress also shows a downward trend as a whole. Through orthogonal experimental design, the optimal combination of process parameters for high-frequency induction cladding Ni60 alloy coating was determined, as 8500 W power, 120 mm/min speed, 600 μm cladding layer thickness, 23.4% reduction of equivalent stress and 4.7% reduction of maximum deformation, which provided theoretical basis and reference for the protection of boiler water wall tubes.
