Inqubo yokukhiqiza ishubhu yensimbi engagqwali

Ukugoqa okubandayo: ukucutshungulwa kwengcindezi nokwelula kwe-ductility. Ukuncibilika kungashintsha ukwakheka kwamakhemikhali ensimbi. Ukuginqika okubandayo akukwazi ukushintsha ukwakheka kwamakhemikhali ensimbi, ikhoyili izofakwa emigqonyeni ebandayo yemishini yokugoqa isebenzisa ukucindezela okuhlukahlukene, ikhoyili izobanda igoqelwe ebugqileni obuhlukahlukene, bese kuthi ngomqulu wokugcina wokuqeda, ulawule ukunemba kokuqina kwekhoyili, ukunemba okuvamile phakathi kukasilika ongu-3.

I-Annealing: Ikhoyili egoqiwe ebandayo ifakwa esithandweni somlilo esichwepheshile, sishisiswe kumazinga okushisa athile (amadigri angu-900-1100), futhi isivinini sesithando somlilo siyalungiswa ukuze kutholakale ubulukhuni obufanele. Izinto ezizothamba, isivinini sokudonsa sihamba kancane, kulapho izindleko ezihambisanayo ziphezulu. I-201 kanye ne-304 yinsimbi engagqwali ye-austenitic, enkambisweni yokudoba, isidingo sokushisa nokubanda ukulungisa inhlangano ye-metallurgical yenqubo egoqwe ebandayo yonakele, ngakho-ke ukukhishwa kwe-anneal kuyisixhumanisi esibucayi kakhulu. Kwesinye isikhathi i-annealing ayilungile ngokwanele ukukhiqiza ukugqwala kalula.

I-workpiece ishiselwa ekushiseni okunqunywe kusengaphambili, okugcinwe isikhathi esithile bese ipholisa kancane inqubo yokwelapha ukushisa kwensimbi. Inhloso yokukhishwa yilezi:

1 ukuthuthukisa noma ukuqeda insimbi ekubunjweni, ukubumba, ukugoqa kanye nenqubo yokushisela okubangelwa ukukhubazeka okuhlukahlukene kwenhlangano nokucindezeleka okusalayo, ukuvimbela ukuguqulwa kwe-workpiece, ukuqhekeka.

2 thambisa umsebenzi wokusika.

3 cwenga okusanhlamvu, uthuthukise inhlangano ukuze uthuthukise izakhiwo zemishini ye-workpiece. Ukulungiswa kwenhlangano kokwelashwa kokushisa kokugcina nokwenza amapayipi.

I-Slitting: ikhoyili yensimbi engagqwali, inqunywe ububanzi obuhambisanayo, ukuze kuqhutshekwe ukucubungula okujulile nokwenza amapayipi, inqubo yokusika idinga ukunaka ukuvikela, ukugwema ukunwaya ikhoyili, ukusika ububanzi nephutha, ngaphezu kokusika Ubudlelwano phakathi kwenqubo yokwenza ipayipi, ukusika komugqa wensimbi kwavela eqoqweni lama-fronts nama-burrs, ukusika kuthinta ngqo isivuno sepayipi elishiselwe.

I-Welding: inqubo ebaluleke kakhulu ye-stainless steel tube, insimbi engagqwali isetshenziswa kakhulu i-argon arc welding, i-high frequency welding, i-plasma welding, i-laser welding. Okwamanje okusetshenziswa kakhulu yi-argon arc welding.

I-Argon arc welding: igesi yokuvikela i-argon ehlanzekile noma igesi exutshwe, ikhwalithi ephezulu yokushisela, ukusebenza kahle kokungena kwe-weld, imikhiqizo yayo embonini yamakhemikhali, yenuzi kanye nokudla isetshenziswa kabanzi.

I-high-frequency welding: ngamandla aphezulu omthombo wamandla, ezintweni ezihlukahlukene, ukushuba kodonga lwangaphandle lwepayipi lensimbi kungafinyelela isivinini esiphezulu sokushisela. Uma kuqhathaniswa ne-argon arc welding, ijubane layo eliphezulu lokushisela izikhathi ezingaphezu kweziyi-10. Isibonelo, ukukhiqizwa kwepayipi lensimbi usebenzisa i-welding high-frequency welding.

I-Plasma Welding: inamandla anamandla okungena, iwukusetshenziswa kokwakhiwa okukhethekile kwethoshi le-plasma elikhiqizwa yi-high-temperature plasma arc, futhi ngaphansi kokuvikelwa kwendlela yokushisela igesi ehlanganisiwe yensimbi evikelayo. Isibonelo, uma ukushuba kwezinto kufinyelela ku-6.0mm noma ngaphezulu, ukushisela i-plasma ngokuvamile kuyadingeka ukuze kuqinisekiswe ukuthi i-weld seam ishiselwe.

Insimbi engagqwali eshiselwe ipayipi eshubhuni lesikwele, ishubhu elingunxande, ishubhu eliyisiyingi, ishubhu elimise okweqanda, ekuqaleni lisuka eshubhuni eliyindilinga, ngokukhiqizwa kweshubhu eliyindilinga elinesiyingi esifanayo bese lakhiwa libe yisimo seshubhu elihambisanayo, futhi ekugcineni lilolonge futhi liqondiswe ngesikhunta. .

Inqubo yokusika ishubhu yensimbi engagqwali inzima kakhulu, iningi labo lisikwa ngama-hacksaw blades, ukusika kuzokhiqiza inqwaba yezinhlangothi; enye i-band saw cutting, isibonelo, ishubhu enkulu yensimbi engagqwali enobubanzi obukhulu, kukhona nenqwaba yama-fronts, iqoqo elijwayelekile lama-fronts kakhulu lapho abasebenzi bedinga ukufaka esikhundleni se-saha blade.

Ukupholisha: Ngemva kokwakhiwa kwepayipi, indawo engaphezulu ipholishwa ngomshini wokupholisha. Ngokuvamile, kunezinqubo eziningana zokwelapha ubuso bomkhiqizo kanye namashubhu okuhlobisa, ukupholisha, okuhlukaniswa ngokugqamile (isibuko), 6K, 8K; futhi sanding ihlukaniswe isihlabathi esiyindilinga nesihlabathi esiqondile, nge 40#, 60#, 80#180#, 240#, 400#, 600#, ukuhlangabezana nezidingo ezahlukene amakhasimende.
