The paper presents the results of the oxygen-activity measurement recorded during the metallurgical processing of cast iron from the beginning of the melting to the inoculation of cast iron. The measurement of oxygen activity was made with specifically developed devices and the probes with a high sensitivity designed for measuring aO in cast iron by Heraeus Electro-Nite Celox Foundry. The oxygen activities in cast iron correlate with the properties of cast ironČlanek je osredinjen na merjenje aktivnosti kisika za vodenje metalurške obdelave litega železa v livarni pri centrifugalnem ulivanju valjev. Članek predstavlja rezultate meritev aktivnosti kisika, spremljane med metalurško obdelavo litega železa od začetka taljenja do inokulacije litega železa. Meritev aktivnosti kisika je bila izvršena s posebno razvito napravo in sondo z veliko občutljivostjo za merjenje aO v litem železu s Celox - Foundry Heraeus ElectroNite. Aktivnosti kisika v litem železu so odvisne od lastnosti litega železaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
