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,modularization and inoculation process is improved. there is an new kind of excellent ductile iron that has no uniform 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 ductile 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.
Keywords: ductile iron; production technology; new development; development direction
