Ukuqina Kwensimbi sekukonke

Ngokuthuthuka okusheshayo kwemboni kawoyela yaseShayina, isidingo sensimbi yezinga eliphezulu siyakhula, futhi insimbi yezinga eliphezulu kufanele icinywe, ngakho-ke ukucwaninga kokucinywa kwensimbi kukonke kubaluleke kakhulu. I-China Heavy Machinery Research Institute iye yasungula "i-dip quenching + i-spray yangaphakathi + i-spin" futhi "ngaphandle kwe-jet shower yangaphakathi + spin" izinqubo ezimbili, kanye nocwaningo nentuthuko ehlobene nomugqa wokucisha, futhi yazuza imiphumela emihle. Kokubili inqubo quenching has izici zayo siqu, eshaweni ngaphandle ngaphakathi jet quenching line ukukhiqizwa kufanelekile uwoyela kahle amapayipi, uwoyela casing, sokuprakthiza ipayipi quenching, kuvumelana jikelele quenching mncane odongeni steel tube; Umugqa wokukhiqiza wokucisha ukucwiliswa ulungele ukuqhathanisa ukujiya kodonga Okukhulu ukuqina okuphezulu kokusebenza okuphezulu kweshubhu elinezindonga eziwugqinsi, futhi imikhiqizo yayo isetshenziswa kakhulu ekuvikelweni kwezwe, amandla enuzi, uwoyela negesi kanye nezimboni zezimoto.

Umugqa wokukhiqiza wokucisha ukucwiliswa
Imishini yasekhaya yokucisha esetshenziswayo njengamanje, kukhona ukukhubazeka kweshubhu eliwugqinsi, njengokuthi (1), ukugoba kwepayipi eliwugqinsi elicima kalula, ubuqotho, ubundingilizi bumpofu, ukuze kube nobunzima obulandelayo bokubumba; (2) ipayipi yangaphakathi nangaphandle ayikwazi ukucisha, okuholela Markov okuqukethwe komzimba iphansi, ubulukhuni engalingani; (3) izindleko zokusebenza eziphakeme, ukuvikeleka okubi. Ukusabela kulokhu kushiyeka, ucwaningo oluzimele lwesibhedlela nokuthuthukiswa, amasethi aphelele okukhiqiza ukusetshenziswa kokuqala komhlaba “kokucima ukucwiliswa + Zungezisa + isifutho sangaphakathi” sokucisha ugqinsi lwamapayipi ensimbi kuno-20 mm kusukela kumugqa wokukhiqiza wokucisha wokucisha wokucwiliswa ngokuphelele. Umzila wenqubo uthi: okokusebenza okuqinile kwesithando somlilo sensimbi → igeji yokufika egibele ilifti izungezisa ngokushesha kusho ukucindezela kusho ukucindezela ipayipi lensimbi ledrayivu yesondo → isilinda esiphakamisayo esizungeza ngokushesha ukuze sishayele uhlaka lwensimbi olucwiliswa ngokushesha olucima emanzini → ngaphakathi kwesifutho umlomo wombhobho oya ngaphakathi komjovo wepayipi lensimbi → ukuphela kokucisha, ngaphakathi kwesitobhi sesifutho → mayelana nokuphakamisa isilinda kuzokhuphuka imishayo yensimbi yensimbi → skrola ukuze umise idivayisi yokuphakela idivayisi ngebhulokhi ngayinye ukuya empandeni yamanzi angenalutho ubakaki wepayipi → Amanzi angenalutho asho ukuphakamisa ingxenye eyodwa yepayipi aphakanyiswe ngokuqhubekayo umoya ocindezelwe ocisha amanzi → amanzi → isitebhisi sephayiphi elingaphakathi kwepayipi kancane kancane lithuthelwe kuma-feed roller → insimbi eqinile eqinile. Lokhu ukucwiliswa quenching iyunithi quenching okokuqala ngqa kusetshenziswa "ukucwiliswa quenching + Zungezisa + isifutho sangaphakathi" ubuchwepheshe obusha ububanzi enkulu, obukhulu-walled ishubhu jikelele quenching ukuxazulula enkulu ububanzi obukhulu-ngodonga ipayipi ukugoba quenching, ukucisha izinkinga ezingangenwa zobuchwepheshe; Sizuze le miphumela ebalulekile elandelayo: (1) Ngenxa yezinga lilonke lepayipi lamanzi, ukuzungezisa ngesivinini esikhulu, ukwesekwa okuyisiza kwamaphuzu amaningi, ukuze kube ngcono kakhulu ukuqondisa kwensimbi, okungaphansi kuka-2 mm/m, ukuhlangabezana nezidingo umkhiqizo. (2) kusetshenziswa umsebenzi wokuzungezisa ngaphakathi kwembobo yesifutho esihambayo, kunciphisa ubukhulu bepayipi elivumela ukubhoboza kwepayipi. (3) Ngokucisha ukunyakaza ngaphakathi kwenqubo yokucisha kuguquguquka kakhudlwana, izakhiwo ezifanayo zensimbi zensimbi, ngemva kokucisha izinga lokuguqulwa kwe-martensite elingaphezu kuka-90%, ngisho nama-95%, ubulukhuni nokujiya kokuqondisa kwephutha lepayipi lensimbi lobude obugcwele ≤ 3 HRC.

"Fafaza + ishawa yangaphandle + i-inner spin" inqubo yokucisha.
Le nqubo iwugqinsi oluncane lwedonga lwepayipi. Isithando somlilo esiqinile sensimbi esishiselwe cishe ku-1000 ℃, i-feed roller ibe endaweni okufanele ilindelwe, idivayisi yokuphakelayo ukuze iphakamise insimbi iyiphenyele ijikeleze kancane isho amasondo asekelayo ajikelezayo, ingcindezi ebekwe endaweni yokufafaza iqinisa ngokushesha isho ipayipi elicindezelayo, i-rotary drive isho ukuzungezisa ngokushesha ipayipi lensimbi elizungezayo, ipayipi lensimbi litholakala ngokuqondile ngaphezu kwendawo engaphandle yeshubhu elithelayo liye kusifafaza sepayipi sangaphandle esifana nesaso, kuyilapho isifutho sisho ukufakwa ekugcineni kwepayipi odongeni lwepayipi kuya ekhanda lesifutho. Ngakho izindawo zangaphakathi nangaphandle zepayipi lensimbi ziye zacinywa ngokufanayo.
