Application of yttrium-based heavy rare earth nodularizing agent in high-silicon solution wind power thick and large-section spindle castings
The advantages and disadvantages of the application of high silicon solution process in thick and large section ductile iron are introduced,and the test process of yttrium-based heavy rare earth nodularizing agent in the production of high silicon solid solution wind power thick and large section spindle castings,as well as the selection and control of its production conditions,methods,casting pro-cess and smelting process.Through the detection and analysis of the chemical composition of the wind power spindle,the mechanical properties of the attached casting test block and the metallographic of the body,the results show that the application of yttrium-based heavy rare earth nodularizing agent and reasonable and strict production process design and control measures can realize the application of high silicon solution process to produce thick and large-section wind power spindle castings.
