| Abstract: | by means of the contrast experiment,the effect of micro-chill produced by the white castiron shot containing nodularizing elements,with the addition of 10%,on the microstructure and propor-ties of the medel specimens of heavy section ductile iron is studied,The particular function of micro-chiller in improvlng solidification behavior of heavy section ductile iron is analysed. The poibility ofsolving thoroughly the time effect and space(section) effect during solidification process of hcavy sec-tion ductile iron by using the method is brought forward. |
