Abstract

For behandling av støpejernsstykker er det beskrevet inokulasjonslegeringer som inneholder 0,005 - 3 vekt-% av et element fra gmppen bestående av vismut, bly og antimon, 0,3 - 10 vekt-% metaller fra gmppen av sjeldne jordmetaller og eventuelt aluminium irmtil 5 vekt-% og kalsium irmtil 1,5 vekt-%, idet resten er ferrosilisium, og hvor lantan utgjør mer erm 90 % av de sjeldne jordmetaller som inneholdes i sammensetningen. Legeringene ifølge oppflrmelsen muhggjør effektiv inokulasjon av støpejem og hindrer opptredenen av sprekkdannelse som skyldes mikrokrymping i de støpte deler.For the treatment of cast iron pieces, inoculation alloys containing 0.005 to 3% by weight of an element from the group consisting of bismuth, lead and antimony, 0.3 to 10% by weight of rare earth metals and optionally aluminum of up to 5% by weight are disclosed. % and calcium of up to 1.5% by weight, the remainder being ferrosilicon, with lanthanum making up more than 90% of the rare earth metals contained in the composition. The alloys according to the invention facilitate effective inoculation of the molding material and prevent the occurrence of cracking due to micro-shrinkage in the molded parts.
