O a vaega uamea Sintered:
O vaega u'amea sintered e fa'aaogaina ametotia fa'ameamea o le pauta ta'ua o le sintering. I lenei metotia, o le pauta uʻamea e faʻapipiʻiina i se foliga saʻo, ona faʻaogaina lea o le vevela e faʻapipiʻi ai vaega uʻamea i totonu o le mea na faia, e mafai ai ona faatumauina lona foliga fou.Fa'atainae mafai ona faʻaaogaina e gaosia ai le tele o ituaiga vaega uʻamea ma e fetaui ma le tele o uʻamea eseese ma uʻamea.
JIEHUANGSintered Metals o ni tagata tomai faapitoa i faiga fa'amama fa'ata'ita'i e fa'aliliu ai u'amea pa'u i mea maumea tumau ma fa'alagolago. A'oa'o atili e uiga i le fa'agasologa o le sintering u'amea ma pe fa'apefea ona fesoasoani i lau talosaga e ala i le faitau i luga.
O le a le faiga o le sintering:
Sintering faagasologa o le saunia uʻamea oa pauta, flux, suauu ma suitulaga e tusa ai ma manaoga o le ogaumu blast smelting, e tusa ai ma se vaega patino o batching, fefiloi, faaopoopo vai lubrication. Faʻasalaga, faʻasalalau faʻamalama, faʻatasi ai ma le fesoasoani a le ili, ina ia i lalo o le gaioiga o se maualuga maualuga, o le faʻamaluluina o le paʻu uʻamea uʻamea ma faʻafefeteina, maua ai se vaega vai, ma isi vaega faʻafefeteina mulimuli, pe a maeʻa le malulu, o le vaega vai o le a faʻapipiʻi ai vaega o le paʻu o le minerale i totonu o poloka o lenei faagasologa o le sintering process.
O le faiga fa'avae fa'amau
pa'u pa'u → fa'atonuina (sauniuniga a'o le'i utaina ma fa'alumaina) → fa'alumaina (fa'avevela, fa'asao le vevela ma fa'alili) → sau i fafo → tino fa'amama.
O le a le lelei o vaega uamea Sintered?
●E ala i le sintering, sinter tulaga maualuga ma mautu tuufaatasiga kemikolo, toniga vaega laiti, reducibility lelei ma le maualuga metallurgical faatinoga e mafai ona tuuina atu mo le ogaumu savili, lea e faia ai tulaga lelei mo le tulaga maualuga, fua maualuga, taumafa maualalo ma le ola umi.
●E mafai ona aveese mea leaga e pei o le sulfur, zinc, ma isi;
●O otaota faʻapisinisi, e pei o le pefu o le ogaumu, uʻamea taʻavale, sulfuric acid slag, sila uʻamea, ma isi;
●E mafai ona toe maua mai u'amea non-ferrous ma u'amea eleele.
