Technical Field

[0002] Ductile iron is produced by spheroidizing and inoculating to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially plasticity and toughness, so that ductile iron has higher strength than carbon steel. Ductile iron castings are usually produced by casting.

Usually, the ductile iron parts are cooled by waiting for natural cooling, which consumes a long time and reduces the overall cooling efficiency of the device.
