In the modern manufacturing principle of ductile iron manhole covers, we can forge ductile iron through cast steel and forged steel, which is widely used in the mechanical manufacturing industry today. In fact, the principle of ductile iron is to obtain graphite with the same shape as the ball through the process of spheroidization, which effectively improves the performance of cast iron, especially its plasticity and toughness, resulting in higher quality than carbo...
