Key points for attention in casting processing

1.Before casting, it is important to have a targeted understanding of the different chemical components of pig iron，Know the general chemical composition in it, What are the effects of different chemical composition contents on the quality of ductile iron casting and processing, etc, Then configure pig iron materials with higher quality.

2、The temperature of ductile iron casting process should be controlled well，Generally speaking, It is higher than ordinary gray cast iron，In this way, the temperature drop in the process of pig iron spheroidization can be compensated.

3、The spheroidizing agent should be added in the spheroidizing process of ductile iron casting，Then add some inoculant in the inoculation process.

4、Due to the large fluidity of nodular iron in the process of nodular iron casting，Therefore, it is necessary to reduce the use of higher pouring temperature and larger pouring scale to complete the processing process of ductile iron casting.

5、The heat treatment process of ductile iron casting should include sound annealing, normalizing, modulation and isothermal quenching，In order to meet the casting has good structural quality and thermal stability.
