Cov teeb meem zoo ntawm cov yeeb nkab uas rub txias thiab kev tiv thaiv

Cov yeeb nkab hlau tsis muaj seamless txias ua cov txheej txheem:

① dov txias ② kos duab txias ③spinning

a. Kev dov txias thiab kev kos duab txias feem ntau yog siv rau: kev ua kom raug, phab ntsa nyias, txoj kab uas hla me me, qhov hla tsis zoo thiab cov kav dej muaj zog siab

b. Kev sib hloov feem ntau yog siv rau: kev tsim cov kav hlau loj, phab ntsa nyias lossis cov kav hlau loj heev, thiab feem ntau hloov los ntawm cov kav hlau welded (hlau strip, vuam, kho cua sov, thiab lwm yam)

Cov txheej txheem tseem ceeb ntawm kev tsim cov kav hlau seamless los ntawm kev kos duab txias:

Kev npaj cov yeeb nkab dawb → Kev kos duab txias ntawm cov yeeb nkab hlau → Kev ua tiav thiab kev ua cov yeeb nkab hlau tiav lawm → Kev tshuaj xyuas

Cov yam ntxwv ntawm cov kav hlau tsis muaj seamless uas tsim los ntawm kev kos duab txias (piv nrog kev dov kub)

① Lub cheeb tsam sab nraud ntawm cov yeeb nkab hlau ua me dua kom txog thaum cov hlab ntsha capillary tuaj yeem tsim tau

② Phab ntsa yeeb nkab hlau yog nyias dua

③Cov yeeb nkab hlau muaj qhov tseeb dua thiab qhov zoo dua ntawm qhov chaw

④ Cov duab ntawm cov yeeb nkab hlau yog qhov nyuaj dua, thiab cov yeeb nkab hlau sib txawv thiab cov yeeb nkab hlau tshwj xeeb tuaj yeem tsim tau

⑤ Kev ua yeeb nkab hlau zoo dua

⑥Tus nqi tsim khoom siab, cov cuab yeej loj thiab pwm siv, cov txiaj ntsig qis, cov zis me me, thiab cov kev xav tau kev tiv thaiv ib puag ncig siab dua

Cov teeb meem zoo ntawm cov raj xa dej txias thiab lawv txoj kev tiv thaiv

⒈ Qhov tsis zoo ntawm cov kav hlau txias feem ntau suav nrog: cov phab ntsa tuab tsis sib xws ntawm cov kav hlau, sab nraud txoj kab uas hla tsis kam, qhov tawg ntawm qhov chaw, cov kab ncaj thiab khawb ntawm qhov chaw, thiab lwm yam.

①Qhov tuab ntawm phab ntsa tsis sib npaug ntawm cov kav hlau txias-kos muaj feem cuam tshuam nrog qhov tseeb ntawm phab ntsa tuab ntawm lub raj dawb paug, txoj kev kos duab, qhov chaw kos duab nruab nrab, cov duab qhov, cov txheej txheem deformation thiab cov xwm txheej lubrication.

a. Kev txhim kho qhov tseeb ntawm phab ntsa tuab ntawm lub raj mis yog qhov tseem ceeb ua ntej rau kev txhim kho qhov tseeb ntawm phab ntsa tuab ntawm cov yeeb nkab hlau txias.

b. Lub hom phiaj tseem ceeb ntawm kev rho tawm yam tsis muaj mandrel yog kom txo qhov loj thiab kev hloov pauv

c. Lub qhov zoo li cas yog ib qho tseem ceeb uas cuam tshuam rau qhov tuab ntawm phab ntsa tsis sib npaug ntawm cov kav hlau txias.

d. Nws tseem yog ib txoj hauv kev zoo los xyuas kom meej tias lub raj xa dej zoo, tshem tawm cov hlau oxide nplai ntawm nws qhov chaw, thiab txhim kho qhov zoo ntawm lubrication.

②Thaum lub sijhawm tsim khoom, yuav tsum tau ua tib zoo saib xyuas qhov hnav thiab tsim kua muag ntawm kev sib dhos thiab kev kos duab

③ Txhawm rau kom txo cov kab nrib pleb ntawm qhov chaw ntawm cov yeeb nkab hlau tom qab rub tawm, yuav tsum xaiv cov yeeb nkab uas tsim nyog, thiab cov qhov tsis zoo ntawm cov yeeb nkab yuav tsum tau sib tsoo. Thaum pickling cov yeeb nkab, nws yog qhov tsim nyog los tiv thaiv kev pickling ntau dhau kom tsis txhob muaj pitting lossis hydrogen embrittlement, thiab kom tiv thaiv kev pickling tsis txaus thiab kev ntxuav tsis tiav ntawm cov nplai oxide, xyuas kom meej tias qhov zoo ntawm cov yeeb nkab thaum lub sijhawm siv, siv txoj kev kos duab yeeb nkab tsim nyog, xaiv cov txheej txheem deformation thiab cov duab cuab yeej tsim nyog, thiab txhawb kev kho thiab kev tshuaj xyuas ntawm kab kos duab.

④Txhim kho qhov zoo ntawm cov khoom siv pickling thiab cov roj nplua nyeem ntawm cov yeeb nkab, xyuas kom meej tias cov cuab yeej tawv, sib xws thiab qhov tiav ntawm qhov chaw yuav pab txo qhov tshwm sim ntawm cov kab ncaj thiab khawb ntawm cov yeeb nkab hlau.
