In China,iron castings output amounted to 33.8 million tons in 2014,and the ratio of ductile iron castings to gray iron castings has increased from 0.497 to 0.596 in the past ten years(2004-2014).High carbon equivalent,high strength and low stress gray iron,CGI,ADI,as well as low temperature ductile iron,silicon strengthened ferritic ductile iron,high strength high toughness pearlite ductile iron etc.will be widely used in China.The new techniques for iron casting production have been significantly improved,such as the application of computer technology,casting database systems,modelling and core technology,metal charge,smelting technology,Mg treatment and inoculation technology and equipment,testing,and quality control technology.New goals for the next five-year plan in China are described in this paper.
