Abstract: | The ductile iron production technology of China has made great progress in recent years . That includes that high purity pig iron , raw and auxiliary materials supply is guaranteed , modulariza-tion and inoculation process is improved .there is an new kind of excellent ductile iron that has no u-niform standard , such as silicon reinforced high strength ferrite ductile iron , ferrite ductile iron with high strength and high toughness at low temperature , high strength and high plasticity austenitic duc-tile iron and high Ni austenitic ductile Iron , and specialization of ductile iron castings production , and quality consistency and stability are improved .Now China Is in a critical period from a big country to a stronger with a basic production condition of high quality ductile iron .At the same time , the paper points out the existing problems and future development direction . |
