High purity iron
High purity pig iron is a high-end casting specific iron with low content of harmful elements such as phosphorus, sulfur, manganese, titanium, and very few specific trace elements.
Mainly used for: wind power castings, nuclear power castings, large section ductile iron castings, ductile iron castings with low-temperature impact toughness and fatigue performance requirements, etc. With the transformation of China from a major casting country to a strong casting country, high-purity pig iron has become an urgent demand for many high-end casting enterprises in China, which is of great significance for the development of domestic industries such as wind power, nuclear power, shipbuilding, and high-speed rail.
