Dhuumaha leydiga ah ee aan birta lahayn
Tuubbada Square ee birta ah ee aan birta lahayn waa nooc ka mid ah tuubooyinka.Waxaa jira noocyo wareegsan, labajibbaaran, afargeesle, lix gees iyo noocyo tuubooyin biyo-biyood ah oo ku jira noocyada birta aan-ka-baxa lahayn. Waxaa jira 304, 316 darajooyin ah birta austenitic ah oo inta badan laga isticmaalo warshadaha.Waxa kale oo jira noocyo kale oo ah tuubooyinka birta ah sida duplex, ferritic, martensitic iyo alaabta birta daawaha ah.
Tuubbada labajibbaaran ee birta ah iyo tuubada leydilaha ah waxaa badanaa loo tixraacaa sida birta tuubada ama tuubooyinka qaab dhismeedka.Kuwan waxaa sidoo kale loo tixraacaa inay yihiin qayb qaab dhismeedka godan ama HSS oo gaaban.Loo isticmaalo ujeeddooyin dhismeed, tuubo labajibbaaran, tuubo leydi ah, I beams, iwm, waxaa lagu iibsan karaa noocyo badan oo kala duwan oo bir ah iyo alloys.Soo saarista tuubada labajibbaaran waxay la mid tahay habka wax soo saarka ee tuubada, laakiin alaabtu waxay maraysaa taxane qaabaynta, oo buuxinaysa qeexitaankeedii ugu dambeeyay.
Qaybta iskutallaabta labajibbaaran ee tuubooyinka waxay bixisaa xoog joomatari oo wanaagsan.Sidaa darteed tuubooyinka waxaa loo isticmaalaa codsiyada xoogga badan.Waxaa jira adeegyo heerkul sare ah sida kuwa kulaylka ku shaqeeya oo isticmaala tuubooyinka sidoo kale.Tuubooyinka labajibbaaran ee 316 ss waa kuwo xoog badan oo u adkaysta daxalka.Maaddada 316 waxay ka kooban tahay chromium, nikkel iyo molybdenum.Isku dhafkan wuxuu u oggolaanayaa kororka caabbinta daxalka oo leh 215MPa ugu yaraan awoodda wax-soo-saarka 505MPa ugu yaraan xoogga xajinta.Tuubooyinka ayaa sidoo kale ku shaqeyn kara heerkul gaaraya 870 darajo Celsius.Tuubbada Welded Square ee SS Square waxa ay haysataa kiis loo isticmaalo saliidda iyo gaasta, batroolka, kiimikooyinka petrochemical, dhismaha iyo codsiyada qaabdhismeedka sidoo kale.Waxaa jira darajooyin sare sida SS317 Tubooyinka Square kuwaas oo ka samaysan shay 317 ah kaas oo leh 517MPa ugu yaraan xoogga xajinta.Waxay faa'iido u leedahay codsiyada xoogga badan ee dalbanaya.ASTM A270 Tuubbada Wareega ee aan Xidhiidhka lahayn waxaa loo isticmaalaa cadaadis sare, adeegyada heerkulka sare iyo sidoo kale adeegyada daxalka guud sidoo kale.
Tuubbooyinka labajibbaaran ee birta aan fiicnayn, Habka Wax-soo-saarka
Diyaarinta birta wareega → kululaynta → daloolin kulul → jarista madaxa → pickling → polishing → saliidayn → habka duubista qabow → hoos u dhigista → daaweynta kulaylka xalka → toosinta → jarista tuubada → qajaar → hubinta alaabta dhammaatay.
Tuubbooyinka labajibbaaran ee birta-la'aanta ah, falanqaynta waxqabadka
Birtu waxay la falgali kartaa oksijiinta jawiga si ay u sameeyaan filim oksaydh ah oogada.Osaydhka birta ee ka samaysan birta kaarboonka ee caadiga ah waxay sii wadi doontaa inay oxidize, balaadhiso daxalka oo aakhirka samaysato godadka.Tan waxaa lagu samayn karaa iyadoo la isticmaalayo rinji ama dahaarka birta u adkaysta oksida si loo ilaaliyo dusha sare ee birta kaarboon, laakiin daahan waa filim khafiif ah oo kaliya.Haddii dahaarka uu dhaawacmo, birta hoosteeda waxay bilaabataa inay daxal noqoto.Haddii tuubada birta aan daxalka lahayni ay daxalantahay waxay la xiriirtaa maadada chromium ee birta.Marka maadada chromium-ka ee birta ku jirta ay gaarto 12%, dusha tuubada birta aan lahayn waxay abuurtaa lakabka bakhti iyo oksaydh qani ah oo chromium cufan si loo ilaaliyo dusha sare ugana ilaaliyo reoxidation dheeraad ah.Lakabka oksaydhisku waa mid aad u dhuuban, kaas oo la arki karo dhalaalka dabiiciga ah ee dusha birta, taasoo siinaysa birta aan lahayn meel gaar ah.Haddii filimka chromium hal mar uu dhaawacmo, chromium-ka birta iyo ogsijiinta ku jirta jawiga si ay dib ugu soo nooleeyaan filimka passivation, sii wadaan inay ciyaaraan doorka ilaalinta.Qaar ka mid ah deegaannada gaarka ah, birta daxalka ah waxay sidoo kale u muuqan doontaa qaar ka mid ah daxalka maxalliga ah iyo guul-darrooyinka, laakiin birta-kaarboonka iyo birta kaarboonku way ka duwan tahay, uma muuqan doonto daxal iyo guuldarro isku mid ah, sidaa darteed gunnada daxalka ee tuubada birta-la'aanta waa macno la'aan.
