Pre-Inoculation Effect Of Sic In Production Of Thin Wall Ductile Iron Castings, Nikolay Y. Laukhin

Dissertations and Theses @ UNI

Pre-inoculation effect of SiC additions and its effect on castability, microstructure, and magnesium recovery in thin wall ductile iron plates have been studied. Experimental results were compared with alternative FeSi75 furnace pre-inoculation additions.

The first series of experiments aimed to set the baseline of iron quality, when using FeSi75 pre-inoculant

In the second series of experiment, different methods of introduction of Sic into liquid iron were studied. It was established that Sic added into the stream during the tapping into the flow-through chamber or added directly into the flow-through chamber produced lower Si recovery. The most effective method of introduction …
