Abstract
The paper summarizes research realized by the author in laboratory and
industrial conditions (foundries of cast steel and cast iron, castings
up to 50 tons) on the effects of the chemically hardened molding sands
regeneration using hard/soft rubbing in the dry reclamation.
A reference was simultaneously made to advisability of application of the
thermal regeneration in conditions, where chromite amount in
the circulating (reclaimed) molding sand goes as high as above ten percent. An
advisability of connecting standard and specialized methods
of examination of the reclaimed sands and molding sands made using it was
pointed out. A way of application of studies with the Hot
Distortion PlusĀ® method modified by the author for validation of modeling of
the thermo-dynamic phenomena in the mold was shown.
