| Popis: | The key criteria of the process of graphitizing modification of matrix melt silicon concentration and silicon assimilation evaluated were on samples of gray cast iron grade СЧ20 State Standard 1412-85. These criteria of evaluation on the structure and properties of casting ingots proved an efficiency of intra-mold modification of molten gray cast iron by dispersed ferrosilicon grade ФС75 State Standard 1415-93 (ISO 5445-80) using lost-foam casting (LFC-process). |
