Tulaga lelei ole Fa'a'avevela o Paipa Fa'afa'afa'afa

Ina ia faʻaleleia atili le maaa o luga ma ofuina teteʻe opaipa faatafafā, e mafai ona faagaoioia nisi o luga, e pei o le i luga o le afi mama mama, maualuga, vaeluaga vaeluaga hardening luga ma nisi togafitiga kemikolo ma faapena.E masani lava maualuga, vaeluagalemu taimi faʻamaʻaina luga o le tele, e vevela i le vevela o le 850-950.Ona o lona le lelei o le vevela, o le mea lea e le vave tele le saoasaoa o le vevela, a leai o le a liusuavai ma ni faaletonu e tineia ai ta'eta'ei.Fa'atosina fa'ama'a'a mana'oga Rectangular Pipe normalizing matrix fa'alapotopotoga e tele lava pearlite.Ole vai malulu ole vai po'o se vaifofo vai ole polyvinyl alcohol, vevela vevela ile va ole 200-400, faigata 40-50HRC, maaa ma ofuina teteʻe ina ia mautinoa Rectangular Pipe luga.

E iai fo'i fa'amanuiaga e tolu o lo'o i lalo:

(A) Maualuluga tulaga mautu mo le saʻo paipa rectangular, lea e manaʻomia ai le saʻo maualuga, e tatau ona faatumauina le mautu dimensional, o se taunuuga o le aoga saʻo i le ea, o le cooling fua faatatau e telegese, o lea o le matafaioi a austenite ua mautu o le a faateleina le aofaiga o le taofia. austenite tissue paipa rectangular, e tatau ona malulu togafitiga;

(B) Faʻaitiitia le faʻafefeteina faʻafefe ona o le sikuea faʻaumiumi ma faʻauʻu rectangular, o lea faiga maaa faigofie deformed, e tatau ona matua pulea deformation, vevela togafitiga o se laasaga taua i le faagasologa tineia, le faaaogaina o palasitika e supercooled austenite alignment taimi, lea e o se laasaga autu e mautinoa ai lo latou conformity fua faatatau, lea e tatau ona tineia le taele vevela po o le faamalūina o le vevela straightening fuafuaina mo se taimi ao faavevela e tatau ona tautau i luga o le faamafanafanaina, e faaitiitia le deformation faamaaa i le suauu, mo nofoaafi taiala maualuga-saʻo, e faaitiitia le deformation. o le gas nitriding po'o le plasma nitriding, ma isi;

(C) Maaa maualuga sikuea autu ma rectangular paipa faʻafesoʻotaʻi avega vaivai, e tatau ona i ai se maaa maualuga, ma o lea e tatau ona faʻamaʻaʻaina, poʻo le faʻamaʻaina poʻo togafitiga vevela vevela, sosoo ai ma le faʻafefeteina.
