Anotace:
the article describes using the DMa device for measuring
thermal expansion of different types of sand and
the endurance of the binder system under thermal exposure.
comparison of different core production technologies
(e.g. cold box, cO2 resol, furans, alphaset,
thermoshock, ct— water glass) from the point of view
of the used silica or non-silica sand (chromite, cerabeads,
synthetic alusilicate), dosing of organic or inorganic
binders, additives.
