What are the solutions and technologies of wind power casting process? How to guarantee its casting quality? Let's talk about it with you. The process plan mainly includes modeling process, smelting and pouring process, spheroidizing inoculation treatment and some processes of cleaning. The base of the wind power generation equipment, the hub of the device blades, the gear box, the mechanical stand, etc. are all castings. The main size of the wheel hub is 3175㎜, the main wall thickness is 150㎜; the material grade is QT400-18L; the gross weight is 12300㎏; the molten iron weighs about 17,500㎏. The technical requirements of raw materials for mechanical properties are also very strict. Using the partition method with appropriate chemical composition control, the trial production of wind turbine castings is carried out to meet the higher inherent quality requirements of wind turbine castings, realize mass production, and create conditions for the localization of wind turbines.
