O le eseesega tele i le va o le annealing ma le normalizing:

1. Ole fua ole malulu ole normalizing e sili atu le vave nai lo le faʻafefeteina, ma le maualuga ole supercooling e tele
2. O le fausaga na maua pe a uma le faʻavasegaina e matua lelei lava, ma o le malosi ma le maʻaʻa e maualuga atu nai lo le faʻafefe.

Le filifiliga o le annealing ma normalizing:

1. Mo le maualalo carbon seamless paipa uʻamea ma carbon anotusi itiiti ifo i le 0.25%, normalizing e masani ona faaaoga nai lo annealing.Ona o le saoasaoa cooling fua faatatau e mafai ona taofia le maualalo carbon seamless paipa uʻamea mai timuga o free cementite tertiary i luga o le tuaoi o saito, o lea e faaleleia ai le faatinoga deformation malulu o vaega stamping;normalizing e mafai ona faaleleia le maaa o le uamea ma le tipiina faatinoga o le maualalo carbon seamless paipa uamea.;A leai se isi togafitiga vevela faagasologa, normalizing e mafai ona faamamaina fatu ma faaleleia le malosi o le maualalo carbon seamless paipa uamea.

2. Ole paipa u'amea gaogao fe'avea'i carbon malulu fa'atasi ma le kaponi i le va o le 0.25% ma le 0.5% e mafai fo'i ona fa'amaninoina nai lo le fa'amaluluina.E ui lava o le vaeluaga-carbon uamea malulu tosoina paipa uʻamea ma carbon anotusi latalata i le tapulaʻa pito i luga maaa maualuga pe a uma normalizing, e mafai lava ona tipi, ma le tau normalizing e maualalo ma o le gaosiga e maualuga.

3. O paipa u'amea fa'afefete maalili fa'atasi ma le carbon content i le va o le 0.5 ma le 0.75%, ona o le maualuga o le carbon content, o le ma'a'a'a pe a uma le fa'avasegaina e matua sili atu le maualuga nai lo le fa'afefeteina, ma e faigata ona fa'atinoina le tipiina o le gaosiga, o lea o le mae'a mae'ae'a. e masani ona faʻaaogaina e faʻaitiitia ai le Maaa ma faʻaleleia atili masini.

4. High carbon po'o meafaigaluega uamea ma carbon anotusi> 0.75% o malulu tosoina seamless paipa uʻamea masani faʻaaogaina spheroidizing annealing e avea o se togafitiga vevela muamua.Afai ei ai se sima lona lua meshed, e tatau ona normalized muamua.O le fa'amaluluina o se faiga e togafitia ai le vevela lea e fa'avevela ai le paipa u'amea malūlū e tosoina i se vevela talafeagai, fa'atumauina mo se vaitaimi patino, ona fa'alili malie lea.O le fa'a'alili lemu o le vaega autu lea o le fa'amaluluina.E masani ona fa'alili paipa u'amea fa'apipi'i mālūlū i lalo ole 550 ℃ ile ogaumu ma fa'alili ile ea.O le fa'afefeteina o se fa'aogaina tele o le vevela.I le gaosiga o le gaosiga o meafaigaluega, masini poʻo vaega faʻainisinia, ma isi, e masani ona faʻatulagaina e avea o se togafitiga muamua o le vevela pe a uma ona tuʻuina, faʻamalosi ma uʻamea, ma aʻo leʻi tipiina (talatala) gaioiga e faʻaumatia ai nisi o faʻafitauli na mafua mai i le faagasologa muamua.fa'aletonu, ma sauni mo galuega mulimuli ane.

Fa'amoemoega Fa'asu'i:

①Faʻaleleia pe faʻaumatia faʻafitauli faʻaletonu eseese ma faʻafitauli o loʻo totoe e mafua mai i le sila i le faʻagasologa o le lafo, faʻamalosi, taʻavale ma uʻamea, ma puipuia le faʻaleagaina ma le taʻe o le mea faigaluega;
② faamalulu le mea faigaluega mo le tipiina;
③ Faʻamama le saito ma faʻaleleia le fausaga e faʻaleleia ai mea faʻainisinia o le mea faigaluega;
④ Saunia le faʻalapotopotoga mo togafitiga vevela mulimuli (tineia, faʻafefe).
