On the In-Mould Inoculation of As-Cast Nodular Iron |
| |
| Abstract: | By way of optimization test, the effects of different complex inoculantson the in-mould inoculation of nodular cast iron were investigated. Theresults show that the best inoculating effect is of the Ba--bearing complexinoculants. Furthermore, with the rotational combination design of theexperiment applied to, a mathematical model is developed for the mechanicalproperties of in--mould inoculated nodular cast iron so as to give the optimizedconditions of technological process. |
