Vasega u'amea fa'ameamea kalasika

Silicon-calcium alloy o se uʻamea tuʻufaʻatasia e aofia ai elemene silikoni, calcium ma uʻamea.O se deoxidizer tu'ufa'atasi lelei ma desulfurizer.E faʻaaogaina lautele i le gaosiga o le uʻamea maualuga, uʻamea maualalo, uʻamea uʻamea ma isi mea faʻapitoa faʻapitoa e pei o nickel-based alloys ma titanium-based alloys;e talafeagai foi e fai ma sui mafanafana mo faleaoga u'amea liliu;e mafai foi ona faʻaaogaina e avea o se inoculant mo uʻamea lafo ma faʻaopoopoga i le gaosiga o le uʻamea ductile.

fa'aoga

O le calcium ma le silicon e iai se sootaga malosi mo le okesene.O le calcium, aemaise lava, e le gata o loʻo i ai se vavalalata malosi ma le okesene, ae o loʻo i ai foi le malosi malosi ma le sulfur ma le nitrogen.O le mea lea, o le silicon-calcium alloy o se mea fa'apipi'i tu'ufa'atasi lelei ma so'o fa'a-desulfurization.Silicon alloy e le gata o loʻo i ai le malosi o le deoxidation, ma o oloa faʻamaʻi e faigofie ona faʻafefe ma lafoai, ae mafai foi ona faʻaleleia le faʻatinoga o le sila, ma faʻaleleia le palasitika, aʻafiaga faigata ma le suavai o le uamea.I le taimi nei, e mafai e le silicon-calcium alloy ona sui le alumini mo le deoxidation mulimuli.Fa'atatau ile sila maualuga.Gaosiga o u'amea fa'apitoa ma u'amea fa'apitoa.Mo se faʻataʻitaʻiga, o togi uʻamea e pei o le uʻamea uʻamea, uʻamea maualalo carbon, ma uʻamea uʻamea, ma mea faʻapitoa e pei o nickel-based alloys ma titanium-based alloys, silicon-calcium alloys e mafai ona faʻaaogaina e pei o deoxidizers.Calcium-silicon alloy e talafeagai foi e fai ma sui mafanafana mo faleaoga uamea a tagata liliu.E mafai fo'i ona fa'aogaina le u'amea o le calcium-silicon e fai ma tui mo le u'amea lafo ma se fa'aopoopo i le gaosiga o le u'amea nodular.
