Abstract

"LIGA INOCULANTE PARA FERRO FUNDIDO". A invenção tem por objeto ligas inoculantes destinadas ao tratamento do ferro fundido contendo (em peso) de 0,005% a 3% de um elemento do grupo do bismuto, chumbo e antimónio, de 0,3 a 10% de metais do grupo das terras raras e eventualmente alumínio até 5% e cálcio até 1,5%, o resto sendo o ferro-silício, o lantânio constituindo mais de 90% dos metais de terras raras que entram na sua composição. As ligas de acordo com a invenção permitem uma inoculação eficaz do ferro fundido e evitam a ocorrência de trincas por micro-contração nas peças fundidas."INOCULATING ALLOY FOR CAST IRON". The invention relates to inoculant alloys for the treatment of cast iron containing (by weight) from 0,005% to 3% of a bismuth, lead and antimony group element, 0,3 to 10% of rare earth group metals and eventually aluminum up to 5% and calcium up to 1.5%, the rest being ferro-silicon, lanthanum constituting over 90% of the rare earth metals that come into its composition. The alloys according to the invention allow an efficient inoculation of the cast iron and prevent cracking by micro-shrinkage in the castings.
