文摘Spheroidiser is an important middle alloy for producing ductile iron. Now only chemicalcompositions of spheroidiser was presented by producers in detail. It is just reflecting reactive thermodynamic factors of spheroidiser in melt. But some reactive kinetic factors of spheroidiser in melted iron and its quality stability in melting are not paid attention enough. According to reactive thermodynamics and kinetics of spheroidiser in melt and stability of quality of manufactured spheroidisers during application by statistics.
