dcterms:description
Metal reoxidation during casting influences, and in some cases in a decisive way, quality of products in foundries. Reoxidation processes used to be a cause of irreparable defects of castings as e.g. cavities (gas blowhole, pinholes), macroinclusions, the oxide penetration, slag gas defects and adverse influencing of morphology of oxides and supphides eliminated as microinclusions. Study of available literature has confirmed that this problem was not solved sufficiently from the metallurgical point of vview for conditions of metal casting. For that reason the author describes and analyses the process of reoxidation of liquid metals in a mould and its influence on casting quality.

Reoxidace kovu během odlévání ovllivňuje rozhodujícím způsobem kvalitu produktů ve slévárnách. Reoxidace bývá příčinou nenapravidelných defektů při odlévání jako dutiny (bubliny, bodliny) makrovměstků, oxidické penetrace, plynostruskových bublin a nepříznivého ovlivnění morfologie oxidů a sulfidů vyloučených jako mikrovměstky. Ze studia odborné literatury vyplývá, že tento problém nebyl pro podmínky výroby ocelových odlitků zcela vyřešen. Autoři popisují a analyzují příčiny reoxidace lomu ve formě a jejjí vliv na jakost odlitků.
