铸态球铁件的生产对于节约能源、缩短生产周期和简化生产工序都具有明显的效果，从而产生较高的经济效益。对于铸态铁素体和铸态珠光体球铁的生产，国内外已有不少成功经验，我公司也曾成功地研制过铸态铁素体球铁，但因组织生产困难，使得这一技术没能在生产中推广应用。为了
The production of cast ductile iron has significant effects on energy conservation, shortening the production cycle and simplifying the production process, resulting in higher economic benefits. For the production of as-cast ferrite and as-cast pearlite ductile iron, there have been many successful experiences at home and abroad. Our company has also successfully developed as-cast ferrite ductile iron. However, due to difficulties in organizing production, Technology did not promote the application of production. in order to
