The service performance of nodular cast iron is mainly determined by the microstructure and casting defects, among which the microstructure
Oxygen and sulfur are the main surface active elements, which have an important influence on the change of graphite base
This is a great achievement in the ancient casting iron techniques in our country, and is also a miracle in
