| Abstract: | The effect of Bi Cu inoculant on the production of malleable cast iron is studied. It is found that adding 0.03% Bi and 0.3% Cu to the alloy,the melts can effectively decrease the graphitization time. During graphitization heat treatment, with the contents of inoculant mentioned above, sound casting with density structure and compact graphite can be realized. |
