Original abstract

The effects of inoculation with the aid of OPTIGRAN and GERMALLOY (SKW Trostberg) inoculation bodies placed on ceramic filters on hard-spot depth, structure and mechanical properties have been verified. It has been proved that this method of inoculation reduces chilling tendency in castings very effectively. It increases graphite dispersiveness and improves the plastic properties of ductile iron. The effect of inoculation is dependent on pouring time and sensitive to pouring temperature.

Czech abstract

Byl ověřován vliv očkování očkovacími tělísky Optigran a Germaloy, umístěných na keramickém filtru na zákalku, strukturu a na mechanické vlastnosti. Bylo zjištěno, že toto očkování účinně snižuje sklon k zákalce. Zvyšuje disperzitu grafitu a zlepšuje plastické vlastnosti tvárné litiny. Očkovací efekt závisí na době lití a je citlivý na licí teplotu.
