Resumen:
This paper describes the development of a horizontal and a vertical
mould designed to produce thin ductile iron plates of 1.5 - 4 mm
thickness. Both moulds used a non-pressurised configuration. The
horizontal mould design was based on empirical rules, while the
vertical mould was based on numerical simulations of fluid flow and
thermal field, carried out using the software NovaFlow&Solid. The
aim of both designs was to produce sound ductile iron plates that were
large enough to make tensile test samples. The results show that the
adoption of empirical rules and a non-pressurised configuration were
not enough to guarantee proper filling. An optimized design was
obtained through the use of mathematical modelling.
