HOW TO IMPROVE THE SPHEROIDIZATION RATE OF DUCTILE IRON
The spheroidization level of domestic ordinary spheroidal graphite cast iron castings is required to reach level 4 or above, (that is, the spheroidization rate is 70%), the spheroidization rate achieved by the general foundry is about 85%. In recent years, with the development of nodular cast iron production, especially in industries with high requirements for wind power casting .
