AI Technical Summary
In castings with complex shapes, where the wall thickness varies significantly and the sulfur and oxygen content of the molten iron is low, the lack of nucleation sites during spheroidizing inoculation treatment leads to poor graphitization results.
An oxygen-sulfur composite inoculant, composed of ferrosilicon, ferromanganese, calcium silicon, barium silicon, ferrous sulfide, manganese dioxide, iron oxide, and ferrous oxide, is prepared through smelting, crushing, and sieving. It is used for in-flow inoculation casting to optimize the spheroidization level and graphite size grade.
In castings with complex shapes, ensure that the spheroidization level reaches level 3 and the graphite size level reaches level 6 to meet the basic performance requirements of the casting.
