Seamless steel yeeb nkabyog ib qho tseem ceeb ntawm cov yeeb nkab steel hauv kev tsim khoom thiab lub neej. Nws yog ib qho tseem ceeb ntawm cov khoom siv hlau nrog lub zog siab thiab ua haujlwm ntev ntawm cov kav hlau. Seamless steel kav kuj yuav ntsib kev khoov thiab deformation thaum siv. Thaum ntsib dabtsi yog khoov deformation ntawm seamless steel kav, seamless steel kav yuav siv tau txuas ntxiv mus ntev npaum li lawv tuaj yeem kho.
Cov txheej txheem dabtsi yog khoov tuaj yeem cuam tshuam rau cov khoom siv thiab kev ua haujlwm ntawm cov yeeb nkab, yog li yuav tsum tau ua tib zoo xaiv cov txheej txheem khoov uas tsim nyog. Rau cov kav dej seamless steel, cov txheej txheem khoov muaj xws li khoov txias thiab kub dabtsi yog khoov, thiab txhua txoj kev muaj nws cov sijhawm siv tau.
Txwv tsis pub, kev siv cov yeeb nkab seamless steel yuav raug cuam tshuam. Kev khoov qib ntawm seamless steel kav kuj tuaj yeem tswj tau, uas yuav tsum tau tswj los ntawm cov hauv qab no:
Kev tswj cov qib dabtsi yog khoov ntawm seamless steel kav thaum quenching tuaj yeem ua los ntawm cov hauv qab no:
(1) Txais yuav cov txheej txheem txias txias ntawm txheej txheej ua ntej thiab tom qab ntawd txau sab hauv. Vim tias cov dej txau hauv cov yeeb nkab seamless steel ntws los ntawm ib qho kawg ntawm cov yeeb nkab steel seamless mus rau lwm qhov kawg, cov cua txias ntawm ob qhov kawg ntawm cov yeeb nkab seamless steel yog sib txawv, ua rau cov yeeb nkab seamless steel yeeb nkab khoov. Yog li ntawd, cov dej txias sab nraud tuaj yeem siv ua ntej los ua qhov kev hloov pauv ntawm cov txheej txheem ntawm cov yeeb nkab seamless steel ua ntej, thiab tom qab ntawd cov dej hauv cov dej txias txias tuaj yeem siv kom tsis txhob khoov deformation ntawm seamless steel yeeb nkab. Cov tshuaj tsuag dej sab hauv muaj lub sijhawm ncua ntev txog 2 ~ 10 vib nas this piv nrog lub taub hau sab nraud.
(2) Txo qhov ntev ntawm qhov txuas kawg ntawm seamless steel yeeb nkab ntawm lub log tig. Los ntawm kev tsim nyog khiav thiab seamless steel yeeb nkab ntev tswj, tswj qhov kawg overhang ntawm seamless steel yeeb nkab kom tsawg dua los yog sib npaug li 600 hli tuaj yeem txo cov centrifugal quab yuam thaum lub sij hawm quenching thiab txo qhov khoov degree ntawm seamless steel yeeb nkab kawg.
(3) Tsim nyog tswj tus khiav ceev.
(4) Tswj qhov nruab nrab ntawm cov dej quenching log. Qhov sib txawv ntawm qhov chaw khiav dej num muaj kev cuam tshuam zoo rau kev khoov ntawm cov yeeb nkab steel seamless thaum quenching. Tom qab kev tshawb fawb, qhov chaw nruab nrab ntawm tus khiav yuav tsum tau tswj tsis pub dhau 0 txog 5 hli.
(5) Tswj tus nqi thiab qhov sib xws ntawm cov tshuaj tsuag dej sab hauv thiab sab nraud. Thaum cov roj zoo yeeb nkab quenching txias tau txais cov txheej txheem ntawm txheej txheej laminar ntws txias thiab cov dej hauv axial txhaj tshuaj, qhov loj thiab qhov sib xws ntawm kev txhaj tshuaj dej sab nraud, qhov loj ntawm cov dej txhaj tshuaj thiab cov kev sib dhos ntawm cov nozzles kuj tseem ceeb.
