With the development trend of ductile iron is to develop into a thick bulky, nodulizer alloy material as manufacturers become more and more important in the eyes of Changzhou Wei, below about spheroidizer in ductile iron in the process of action, and understanding of the various elements of the role?

The ball as the name suggests, seeking to melt, and seek to melt, he is to make the graphite in the cast iron into a ball and add the additive called the ball of iron. Magnesium is the strongest element in the ability of the ball, and the addition of rare earth is more stable, is to eliminate the role of anti - ball elements, so that it can not be affected by other anti - ball elements. Calcium stable, can play a long-term breeding. But the ability to be weak, adding a large amount of metal calcium is very easy to oxidation, and will produce waste, can not be used alone.
