INVESTIGATION OF EFFICIENCY OF GRAY CAST IRON GRAPHITIZING MODIFICATION BY DISPERSION-FILLED CONSUMABLE PATTERN
Abstract
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).
