Shiinaha ASTM A53 Gr.B Dhuumaha Birta Kaarboon ee Kulul ee aan Xirnayn
Sharaxaad Gaaban:
Dhuumahan Alloy Steel ee leh 12cr1MOV Material waa tuubo bir ah oo aan waxba tarayn oo loo isticmaali karo batroolka, kiimikooyinka, korontada iyo codsiyada kuleyliyaha.Waxay leedahay sifooyin caabbinta qabow, caabbinta kulaylka iyo caabbinta daxalka.12Cr1MoV waa nooc ka mid ah tuubooyinka daawaha.Ujeedada ugu weyn waa in la sameeyo qaybo qaab dhismeedka birta ee kuleyliyaha.
U hoggaansanaanta mabda'a "tayada, adeegga, hufnaanta iyo kobaca", waxaan kalsooni iyo ammaan ka helnay macmiilka gudaha iyo kan caalamiga ah ee Shiinaha ASTM A53 Gr.B tuubo bir ah oo kulul oo duuban, wixii su'aalo dheeraad ah ama haddii aad wax su'aal ah ka qabtid alaabtayada, iska hubi inaadan ka labalabayn inaad na soo wacdo.
U hoggaansanaanta mabda'a ah "tayada, adeegga, hufnaanta iyo korriinka", waxaan ka helnay kalsooni iyo ammaan macmiilka gudaha iyo kan caalamiga ahShiinaha Steel Dhuumaha iyo Dhuumaha Kaarboon, Waxaan si sii kordheysa u ballaarineynaa saamigayaga suuqa caalamiga ah iyadoo ku saleysan alaab tayo leh, adeeg heer sare ah, qiimo macquul ah iyo gaarsiinta waqtiga.Fadlan nala soo xidhiidh wakhti kasta wixii macluumaad dheeraad ah.
Heerkulka adeeggu waa 580 ℃, iyo saxanka birta ah ayaa looga baahan yahay inuu yeesho awood heerkul sare leh.Saxanka birta ah waxaa lagu keenaa xaalad caadi ah oo xanaaqsan.12Cr1MoVG dhuunta daawaha waxay ku salaysan tahay birta qaab dhismeedka kaarboon oo tayo sare leh, iyo hal ama dhowr walxood oo daawaha ah ayaa si habboon loogu daray si loo hagaajiyo sifooyinka farsamada, adkaanta iyo adkaanta birta.Alaabooyinka ka samaysan birta noocan oo kale ah waxay badanaa u baahan yihiin daaweyn kuleyl ah (caadiyan ama deminta iyo xanaaqa);Qaybaha iyo qaybaha ay ka samaysan yihiin inta badan waxay u baahan yihiin in la maro deminta iyo xanaaqa ama daawaynta kiimikada dusha sare (carburizing, nitriding, iwm.), deminta dusha sare ama deminta soo noqnoqoshada sare ee isticmaalka ka hor.Sidaa darteed, marka loo eego halabuurka kiimikaad ee kala duwan (inta badan kaarboonka), hababka daaweynta kulaylka iyo codsiyada, birta noocan oo kale ah ayaa qiyaas ahaan loo qaybin karaa birta la kariyey, la demiyey oo la dabcay iyo nitrided.
Marka hore, waxa dib loo warshadayn karaa 100%, tamarta-badbaadinta iyo ilaalinta deegaanka.
Marka labaad, waxay leedahay caag aad u sarreeya waxaana loo isticmaali karaa wax soo saarka sare iyo habaynta.
Saddexaad, waxa ay leedahay kulaylka wanaagsan iyo awood heerkul sare.
Afar, waxa ay leedahay iska caabin oksaydh oo wanaagsan iyo iska caabin daxalka.
Shanaad, waxa ay leedahay wax qabad qabow iyo kulayl wanaagsan.
12Cr1MoVG waa nooc ka mid ah birta birta ah ee chromium molybdenum, kaas oo qaybaha ugu muhiimsan ee kiimikooyinka ay yihiin kaarboon 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, fosfooraska aan ka badnayn 0.035, baaruud aan ka badnayn 0.030.0.9 chromium. molybdenum 0.25-0.35, alum 0.15-0.30, iwm.
Marka hore, waxaa inta badan loo isticmaalaa in lagu soo saaro tuubooyinka daawaha cadaadiska sarreeya ee kululaynta dusha sare ee kuleyliyaha tuubada biyaha oo leh cadaadis sare iyo ka sarreeya.
Marka labaad, waxaa si weyn loogu isticmaalaa kuleyliyaha sare, madaxyada iyo tuubooyinka uumiga ugu weyn ee cadaadiska sare ee guriga, cadaadiska aadka u sarreeya iyo kuleyliyaha saldhigga tamarta hoose.
Seddexaad, tuubooyinka dhexroorka waaweyn ayaa inta badan loo isticmaalaa madax ahaan iyo marinnada Steam-ga ugu weyn oo leh cabbirro uumi ka hooseeya 565 ℃.
Marka hore, qulqulka kulul (tubbada birta aan fiicneyn ee extrusion) socodka socodka:
Tuubada wareegta ah → kululaynta → daloolin → saddex duub oo iskutallaabta duuban, galootin joogto ah ama extrusion → tuubooyinka jeexjeexa → cabbirka (ama yaraynta) → qaboojinta → biilka → toosinta → tijaabada hydrostatic (ama ogaanshaha cilladaha) → calaamadaynta → bakhaarka.
Midda labaad, sawirka qabow (rogid) socodka habka dhuumaha birta ah ee aan sinnayn:
Billet tube wareeg ah → kululaynta → daloolin → ciwaanka → dajinta → pickling → daahan saliid (dhoobo naxaas ah) → bas badan oo sawir qabow (rogid qabow) → tuubada billet → daaweynta kulaylka → toosinta → hydrostatic test (ama ogaanshaha cillad) → calaamadaynta → bakhaarka.

U hoggaansanaanta mabda'a "tayada, adeegga, hufnaanta iyo kobaca", waxaan ka helnay kalsooni iyo ammaan macmiilka gudaha iyo kan caalamiga ah ee Shiinaha STM A53 Gr.B Dhuumaha Kaarboon Bir La'aanta ah ee Kulul, Wixii su'aalo dheeraad ah ama haddii aad wax su'aal ah ka qabtid alaabtayada, iska hubi inaadan ka waaban inaad na soo wacdo.
Shiinaha Steel Dhuumaha iyo Dhuumaha Kaarboon, Waxaan si sii kordheysa u ballaarineynaa saamigayaga suuqa caalamiga ah iyadoo ku saleysan alaab tayo leh, adeeg heer sare ah, qiimo macquul ah iyo gaarsiinta waqtiga.Fadlan nala soo xidhiidh wakhti kasta wixii macluumaad dheeraad ah.
