Study on Recarburization Process and Microstructure of Synthetic Cast Iron
The influence of recarburization rate in synthetic cast iron,which included adding method of recarburizer,composition of molten iron(e.g.C,Si,Mn) and carbureted temperature,were researched.The microstructure of synthetic cast iron and non-synthetic cast iron were also analyzed.The results show that the nodular graphite is much more,smaller and much symmetrical in synthetic cast iron than in non-synthetic cast iron;the ferrite in the matrix increases slightly in synthetic cast iron;the grain size and pearlite piece are smaller.
