Research on Casting Technology of Ultra-supercritical Nickel-based High-temperature Alloy Ultra-high Pressure Inner Cylinder at 650℃
This article introduces the research work and related production experiences of 12t ultra-high pressure inner cylinder casting technology with nickel-based high-temperature alloy for coal-fired power generation units with high parameters.Based on the material characteristics of nickel-based high-temperature alloy and the structural characteristics of ultra-high pressure inner cylinder castings,MAGMA software is applied to carry out the simulation calculation of the coupling of filling,solidification,and stress fields.Combined with years of production and manufacturing experiences,a reasonable casting process plan is formulated.At present,the production of rough casting has been completed,and after testing the chemical composition,apparent quality,and size of the casting,it meets the relevant requirements,providing experiences for subsequent engineering manufacturing.
