For steel castings, the quality performance of phosphorus is less than 3.0%. Phosphorus in nodular cast iron does not harm spheroidization, but it can melt in molten iron to reduce the eutectic carbon content of iron, carbon and manganese steel, so it is harmful to the original elements. Copper makes the mechanism high density, and decomposes and improves the uniform distribution of graphite, which can not only reduce the white tendency of pig iron, but also reduce the critical temperature of austenite change, decompose and enhance ferrite, which is beneficial to cross-section sensitivity.
