Abstract
Casting quality depends on many factors including the quality of the input
materials, technology, material securing and last but not
least, the mould into which the casting is casted. By pouring into a
single-shot mould, based mainly on 1st generation binders, is is a very
important factor. Basically, a bentonite mixture represents either a
three- or four-component system, but each component of the system is a
heterogeneous substance. This heterogeneity punctuates mainly a
non-stationary heat field, presented throughout the whole process of the
casting production. The most important component is a binder and in the
case of first generation binders mostly bentonites are used - clays that
contain minimum of 80% of montmorillonite
