Qiimaha ugu hooseeya DIN 1629 St52 Dhuumaha Birta aan Xumaan lahayn ee Tayada Sare leh
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.
Anagoo adeegsanayna tignoolajiyada hormuudka ah iyo sidoo kale ruuxayada hal-abuurka, iskaashiga labada dhinac, faa'iidooyinka iyo koritaanka, waxaanu dhisi doonaa mustaqbal barwaaqo leh si wadajir ah shirkaddaada sharafta leh ee Qiimaha ugu hooseeya DIN 1629 St52 Dhuumaha Birta aan Xumaan lahayn ee Tayada Sare leh, Waad ku mahadsan tahay qaadashada waqtigaaga qiimaha leh inaad na soo booqato oo aad rajaynayso inaan wada shaqayn fiican kula yeelano.
Anagoo adeegsanayna tignoolajiyada hormuudka u ah iyo sidoo kale ruuxayada hal-abuurka, iskaashiga labada dhinac, faa'iidooyinka iyo koritaanka, waxaanu dhisi doonaa mustaqbal barwaaqo leh si wadajir ah shirkaddaada sharafta lehShiinaha DIN 1629 St52 Dhuumaha BirtaShaqo adag si aad u sii wadato horumarka, hal-abuurka warshadaha, samee dadaal kasta oo aad ku gasho ganacsiga heerka koowaad.Waxaan isku daynaa sida ugu wanaagsan si aan u dhisno qaabka maamulka sayniska, si aan u barano aqoonta khabiiro badan, si loo horumariyo qalabka wax soo saarka sare iyo habka wax soo saarka, si loo abuuro badeecada tayada leh ee ugu horeysa, qiimo macquul ah, tayada sare ee adeegga, gaarsiinta degdega ah, si aad u soo bandhigto inaad abuurto qiimo cusub .
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 ka kooban kiimikooyin 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.
