Ia manatua "Faʻatau muamua, Sili muamua" i lou mafaufau, matou te galulue vavalalata ma a matou tagata faʻatau ma tuʻuina atu ia i latou auaunaga lelei ma faʻapitoa moSaina Su'e Su'e, Su'e Su'e Su'e, Afai e te tuʻuina mai ia i matou se lisi o oloa e te fiafia i ai, faʻatasi ai ma faʻataʻitaʻiga ma faʻataʻitaʻiga, e mafai ona matou auina atu ia oe upusii.E tatau ona e imeli sa'o mai ia i matou.O la matou sini o le fa'atuina lea o so'otaga fa'apisinisi mo se taimi umi ma manuia fa'atasi ma tagata fa'atau i totonu ma fafo.Matou te tulimatai atu e maua lau tali vave.
Folasaga puupuu:
u'amea u'amea, e ta'ua fo'i o le u'amea lafo, u'amea nodular, u'amea graphite spherical, u'amea spherical graphite ma u'amea SG, o se ituaiga o u'amea-mau'oa graphite na maua i le 1943 e Keith Millis.E ui o le tele o ituaiga o u'amea lafo e vaivai i le vevesi ma malepelepe, u'amea ductile e sili atu le aafiaga ma le vaivai tetee, ona o lona nodular graphite inclusions.O le u'amea pa'u'u e le o se mea e tasi ae o se vaega o se vaega o mea e mafai ona gaosia ma le tele o mea totino e ala i le pulea o latou microstructure.O le uiga masani o lenei vaega o meafaitino o le foliga o le graphite.I u'amea ductile, graphite i foliga o nodules nai lo flakes pei o le u'amea efuefu.A'o pa'u ma'ai graphite e fa'atupuina ai le fa'amafa'aga i totonu o le u'amea, o nodul lapotopoto e taofia ai le fa'atupuina o ta'eta'ei, ma fa'apena ai le fa'aleleia atili o le ga'o lea e fa'aigoaina ai le fa'aigoa.
Austempered ductile iron (ADI; ie, austenite tempered[7]) na maua i le 1950s ae na fa'atauva'a ma maua manuia i nai tausaga mulimuli ane.I le ADI, o le fausaga uʻamea o loʻo faʻaogaina e ala i se faiga faʻafefe vevela.
Tulaga
Fa'asagaga fa'atele (%) mo u'amea ferritic ductile [8]
O isi u'amea ductile e masani ona i ai se vaega itiiti o le sulfur.
Carbon, 3.2–3.60%
Siliko, 2.2–2.8%
Manganese, 0.1–0.2%
Manesium, 0.03–0.04%
Phosphorus, 0.005–0.04%
Sulfur, 0.005–0.02%
Kopa, <0.40%
Uamea, paleni
O elemene e pei o le kopa poʻo le apa e mafai ona faʻaopoopoina e faʻateleina ai le malosi ma maua ai le malosi aʻo faʻaititia i le taimi e tasi.E mafai ona ausia le faʻaleleia atili o le faʻafefeteina e ala i le suia o le 15-30% o le uʻamea i totonu o le uʻamea ma le tele o nikeli, kopa, poʻo le chromium.
Silicon e avea o se elemene fausia graphite e mafai ona sui vaega i le alumini e maua ai le puipuiga oxidation sili atu.[9]
HONGDA u'amea u'amea:
I le amataga o le 2021, na fausia ai e HONGDA se falegaosimea fou e faʻafeiloaʻi ai meafaigaluega ma laina gaosiga mo le faʻaaogaina o le uʻamea.
1. Mea: QT450 #-10 ma Spheroidization fua faatatau i luga o le tulaga III e maua ai se tulaga lelei o castings e lagolago lau talosaga.
2. Laina gaosiga otometi e oʻo atu i le maualuga maualuga ma le tele o le gaosiga gafatia, 550T / Masina, e toe faʻafoʻi ai lou manaʻoga faanatinati.
3.Applications: ductile uʻamea castings mo roller collar, idler bracket ma faapena e pei o vaega castings i totonu 70KGS.Bear "Customer muamua, Excellent muamua" i le mafaufau, matou te galulue vavalalata ma o tatou tagata faatau ma tuuina atu ia i latou auaunaga lelei ma faapitoa mo Top Grade Saina Sumitomo Excavator Parts Sh60 Sh120 Sh280 Sh200 Sh300 Sh400 Sh450 Track Adjuster Assembly mo Idler, O la matou pisinisi o loʻo tuʻuina atu lena "faʻatau muamua" ma tuuto atu e fesoasoani i tagata faʻatau e faʻalauteleina a latou pisinisi laiti, ina ia avea i latou ma Pule Sili!
Vasega MaualugaSaina Su'e Su'e, Su'e Su'e Su'e, Afai e te tuʻuina mai ia i matou se lisi o oloa e te fiafia i ai, faʻatasi ai ma faʻataʻitaʻiga ma faʻataʻitaʻiga, e mafai ona matou auina atu ia oe upusii.E tatau ona e imeli sa'o mai ia i matou.O la matou sini o le fa'atuina lea o so'otaga fa'apisinisi mo se taimi umi ma manuia fa'atasi ma tagata fa'atau i totonu ma fafo.Matou te tulimatai atu e maua lau tali vave.
