Fayodhowrka heerka fayadhowrka aan kala go 'lahayn ee habka wax soo saarka birta-soo-saarka birta - duuban birta wareega - daloolista - sawir qabow - duubid qabow - annealing dhalaalaya - polishing dusha gudaha - dhalaalid dusha dibadda - kormeerka iyo aqbalid - kaydinta baakadaha.
Soo saarista wershada ee heerka fayadhowrka ee tuubooyinka birta ah ee aan fiicnayn ee ka yimid sawir qabow. Sharaxaadda dhowr qalab oo muhiim ah: 1, mashiinka tuubbada sawiridda qabow: bir wareegsan oo daloolsan ka dib tuubada loo yaqaan, tuubada guud waa ф 65 * 5mm ama ф 100 * 7mm.
Guud ahaan warshadaha nadaafadda ahama birta tuubooyinka ka ф 14 * 1mm in ф 200 * 3mm, si baahida loo qabo in la ballaariyo tube iyo jiid tube yar yar, mashiinka sawir qabow si ay u fuliyaan. Mararka qaarkood balaadhinta tuubo badan ama tuubo ayaa loo baahan yahay, halka nuugista (daawaynta kulaylka) iyo wareegyada pickling la sameeyo. Noocyada iyo sifooyinka mashiinka tuubada sawir-qaboojinta iyo noocyada mandrel iyo qeexitaannada lama sifayn. Faa'iidooyinka ugu muhiimsan ee sawirka qabow waa: waxtarka wax soo saarka sare; Way ku habboon tahay oo dabacsan tahay in la beddelo sifooyinka alaabta inta lagu jiro wax soo saarka.
Qalabka iyo samaynta qalabka iyo dayactirka qaab-dhismeedka qalabku waa kuwo fudud. Khasaaraha ugu weyn ee sawir qabow waa: qallafsanaanta kaarka waa yar yahay, sidaas darteed kaarka farsamaynta ayaa ka badan, wareegga wax soo saarka ayaa dheer; Isticmaalka birta ayaa sarreeya. Dhammaystirka liidata ee gudaha iyo dibadda ee tuubada. 2. Mashiinka duubista tuubada qabow ee badan: waa qalabka muhiimka ah ee lagu soo saaro birta birta ah ee nadaafadda ee Shiinaha. Dhexroorka dibadda iyo dhumucda gidaarka tuubada birta qabow-jiiday waxay ka yar tahay 0.02-0.05mm ka dib duubista qabowga.
Dhammaadka gudaha iyo dibadda ee tuubada waa Ra≤0.8μm, dhumucda gidaarkana waxa laga samayn karaa ilaa 0.5mm. Ka dib dhalaalidda, dusha gudaha iyo dibadda ee tuubada waxay gaari kartaa Ra≤0.2-0.4μm (sida muraayadda). Noocyada iyo waxyaabaha gaarka ah ee tuubooyin qabow oo duuban oo badan iyo noocyada mandrel lama sifayn.
Khasaaraha ugu weyn ee tuubada duubista qabow waa xaalad adag, taas oo ah, xoogga isugeynta dabacsanaanta waa weyn yahay, kuma habboona ballaarinta, foorarsiga, si adag u hadla, ama aan la kulmin heerarka qaranka, sidaas darteed waa lagama maarmaan in la fuliyo. daaweynta adkeynta kulul (annealing). Guud ahaan, tuubada birta ah waxaa lagu daaweeyaa foornada kulul ee caadiga ah (foornada caanaha), miisaanka oksaydhka ee gudaha iyo dibadda ee tuubada waxay u baahan tahay pickling, taas oo baabi'inaysa dhamaystirka gudaha iyo dibadda ee tuubada asalka ah ee qabow, iyo muuqaalka kore ee aan sinnayn yar, oo aan ilaa heerka fayadhowrka ee heerka dhamaystirka dusha tuubooyinka. Sidaa darteed, ilaalinta gaaska foornada foornada dhalaalaysa waa in la doortaa.
Fayodhowrka heerka fayadhowrka ah ee aan xudduudaha lahayn ee birta birta ah ayaa ka yar 50% birta iyo 10.5% chromium, iyo sidoo kale ku dar sida nikkel, titanium, molybdenum, iwm. kaas oo leh martensite body, ferrite body, austenitic body, double wejiga, roobab adag adkaynaya ahama. Tubooyinka birta aan fiicnayn ee darajada fayodhowrka ayaa sidoo kale lagu heli karaa walxo kala duwan. Warshadaha guud sida caadiga ah loo isticmaalo tube austenitic ahama wax ka badan; 0Cr19Ni9 (USU304), 00Cr19Ni11 (USU 304L), 0Cr17Ni12Mo2 (USU 316), 00Cr17Ni14Mo2 (USU 316L), 1Cr18Ni9Ti (SUS 321), iyo wixii la mid ah. iyo sidoo kale shuruudaha dhamaystirka dusha sare ee gudaha iyo dibadda ee tuubada birta. Dooro heerka fayadhowrka tuubooyinka birta aan lahayn ee leh nooca dareeraha dhexdhexaadka ah, feejignaanta, heerkulka, cadaadiska, xawaaraha socodka, iyo arrimo kale.
