Abstract

patente de invenção; núcleos na base de sal, processo para a produção dos mesmos e uso dos mesmos. altas exigências são feitas a núcleos, que no fundição sob pressão de peças de metal são inseridas no molde, para manter livres os espaços vazios previstos nas peças, no enchimento dos moldes com a fusão, no que se refere à sua estabilidade de forma e possibilidade de remoção dos espaços vazios. de acordo com a invenção, são previstos, portanto, núcleos na base de sal, que podem ser produzidos por moldação e compactação de uma mistura de materiais de nícleo, sendo que esses materiais de núcleo são selecionados de pelo menos um sal, pelo menos um aglutinante e, opcionamente, de adjuvantes, tais como aditivos, materiais de enchimento, agentes de umectação e cates, sendo que o sal, o aglutinante e os adjvantes opcionalmente usados da mistura de materiais de núcleo são inorgânicos e esses materiais de núcleo são solúveis com água como solvente.patent of invention; salt-based cores, process for salt production and use. high demands are placed on cores, which in die casting of metal parts are inserted into the mold to keep the voids provided in the parts free, to fill the molds with the melt, as regards their shape stability and possibility removing voids. According to the invention, there are therefore provided salt-based cores which can be produced by molding and compacting a mixture of core materials, such core materials being selected from at least one salt, at least one salt. and optionally adjuvants such as additives, fillers, wetting agents and cates, the optionally used salt, binder and water as a solvent.
