PRODUCTION OF FILLING MATERIAL OF THE MOULD FOR MANUFACTURING OF METALLIC FOAMS WITH IRREGULAR INNER STRUCTURE

Popis výsledku v původním jazyce

The article presents the technology of manufacturing of precursors (special kind of filling mould material) for possibility to create a complex internal structure of the metallic foam casting. Due to the purpose for which the precursors are used, they must meet specific criteria. The material of the precursors must be sufficiently refractory to come into contact with the liquid metal, and the individual particles must also resist the movement of the melt within the mould. At the same time, however, in the context of this metal foam technology, it is essential that the precursors exhibit excellent collapsibility after casting - i.e. that they are easily removable from the resulting complex casting. Therefore, one of the conventionally used core mixtures appears to be the ideal material for the production of precursors. In this paper, the technology for the production of spherical precursors from a furan self-hardening mixture is described and verified. The motivation for the choice of material and all the sub-steps of the process - moulding into the core, tumbling, including the necessary accompanying tests of the mechanical properties of the core mixture being verified - are described.
