Original abstract
For obtaining a "pure" Fe-C-Si-Me melt the reduction of oxides with carbon in vacuum was suggested. The experiment aimed at studying the change of chemical composition of molten cast iron during holding it on temperature in vacuum, change of oxygen and nitrogen contents during vacuumizing. Influence of different vacuumizing parameters on graphite morphology was further on studied on metallographic samples as well as composition of inclusions found out in cast iron. Cast iron was melted in a crucible from chemically pure aluminium oxide; in a contact point of metal and the crucible the lining was made without use of any binders.
Czech abstract
Pro získání "čisté" taveniny Fe-C-Si-Me byla navržena redukce oxidů uhlíkem ve vakuu. Cílem experimentu bylo sledovat změnu chemického složení během setrvání roztavené litiny na teplotě ve vakuu, změnu obsahu kyslíku a dusíku během vakuování. Dále se sledoval vliv různých parametrů vakuování na morfologii grafitu na metalografických výbrusech a složení vměstků nalezených v litině. Litina byla tavena v kelímku s chemicky čistého oxidu hlinitého místě styku kovu a kelímku byla výduska zhotovena bez použití jakýchkoliv pojiv.
