In spheroidizing the graphite in cast iron by means of calcium-silicide addition, it's recovery and it's spheroidizing effects are usually poor when it is added alone.
The effects of calcium silicide, however, are remarkably improved when it is added jointly with fluxes.
It was revealed that magnesium-fluoride was the most effective flux, for instance, by adding 2.5% calcium-silicide together with 1% magnesium fluoride on the melt in ladle, graphite in the castings was spheroidized.
The above described method of producing the cast iron with spheroidal graphite is less dangerous, less complicated and more reliable compared with the ordinary method of magnesium addition.
