Abstract

In the paper, presented are results of a research on influence of compaction degree on dielectric properties of components of moulding sands. During recent years, intensive research works on possibilities of using microwave heating in foundry technique are carried-out. However, introduction of such innovative, environment-friendly and efficient heating processes to foundry technologies is accompanied by a shortage of basic knowledge about behaviour of components of moulding sands in microwave field. In this case, of particular importance becomes knowledge of electrical properties of components of moulding and core sands, i.e. their permittivity εr and dielectric loss factor tgδ that characterise efficiency of absorbing electromagnetic radiation and thus prove effectiveness of the heating process.
