| Popis: | The results of investigations on optimization of granulometric composition of additives for in-mould graphitizing, carbide stabilizing, and spheroidizing inoculation of cast-iron melt are reviewed and analysed. As revealed, the maximum absorption of graphitizing ferrosilicon inoculant FeSi75 and spheroidizing inoculant FeSiMg7 during treatment of melts in the reaction chamber of a mould is achieved by means of grain size of 5.0 ± 2.5 mm. The most effective inoculative additive for in-mould carbide-stabilizing treatment of cast iron is an alloy of nickel with magnesium of the NiMg15 grade. Independently on the grain size in the range from 1 to 10 mm, the alloy of nickel and magnesium is sufficiently soluble by the flow of molten iron during the mould filling. New technological ways for intensification of in-mould treatment of cast-iron melt using the fine dispersed (including powdery) additives are proposed and studied. |
