Muaj ob pawg ntawm yam uas cuam tshuam rau qhov zoo ntawm seamless raj: steel zoo thiab cov txheej txheem dov.

Ntau yam ntawm cov txheej txheem dov tau tham ntawm no. Qhov tseem ceeb cuam tshuam yog: kub, txheej txheem hloov, cuab yeej zoo, txheej txheem txias thiab lubrication, tshem tawm thiab tswj cov sundries rau saum npoo ntawm dov daim, thiab lwm yam.

1. Kub

Kub yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau qhov zoo ntawm seamless raj. Ua ntej ntawm tag nrho cov, lub uniformity ntawm cov cua kub kub ntawm lub raj dawb paug ncaj qha cuam tshuam rau lub uniform phab ntsa thickness thiab puab nto zoo ntawm perforated capillary, uas nyob rau hauv lem cuam tshuam rau phab ntsa thickness zoo ntawm cov khoom. Qhov thib ob, qhov ntsuas kub thiab qhov sib xws ntawm lub raj seamless steel thaum dov (tshwj xeeb tshaj yog qhov kawg dov kub) muaj feem xyuam rau cov khoom siv kho tshuab, qhov tseeb qhov tseeb thiab qhov zoo ntawm cov khoom xa tuaj hauv lub xeev kub dov, tshwj xeeb tshaj yog thaum lub steel billet lossis tube blank Thaum nws yog overheated los yog overburned, nws yuav ua rau cov khoom pov tseg. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm kub dov seamless raj, cua sov thiab tswj lub deformation kub nruj me ntsis raws li cov txheej txheem yuav tsum tau ua ua ntej.
2. Cov txheej txheem hloov kho
Qhov zoo ntawm cov txheej txheem kev hloov kho thiab kev ua haujlwm zoo feem ntau cuam tshuam rau geometric thiab zoo li zoo ntawm seamless steel hlab.
Piv txwv li, kev hloov kho ntawm lub tshuab tho thiab dov zeb cuam tshuam rau phab ntsa tuab qhov tseeb ntawm cov khoom, thiab kev hloov ntawm lub tshuab sizing yog cuam tshuam nrog cov kab uas hla sab nraud raug thiab ncaj ntawm cov khoom. Ntxiv mus, cov txheej txheem kev hloov kho kuj tseem cuam tshuam seb cov txheej txheem dov tuaj yeem ua tau li cas.

3. Cov cuab yeej zoo
Txawm hais tias cov cuab yeej zoo los yog tsis zoo, ruaj khov los yog tsis, yog ncaj qha ntsig txog seb qhov tseeb qhov tseeb, qhov zoo thiab cov cuab yeej siv ntawm cov khoom tuaj yeem tswj tau zoo; Nto, qhov thib ob yog cuam tshuam rau mandrel noj thiab cov nqi tsim khoom.

4. txheej txheem txias thiab lubrication
Kev ua kom txias zoo ntawm cov tho qhov ntsaws thiab cov yob tsis tsuas yog cuam tshuam rau lawv lub neej, tab sis kuj cuam tshuam rau kev tswj kom zoo ntawm cov khoom sab hauv thiab sab nrauv ntawm cov khoom tiav. Qhov txias thiab lubrication zoo ntawm mandrel ua ntej cuam tshuam rau sab hauv qhov zoo, phab ntsa thickness raug thiab mandrel noj ntawm seamless steel raj; tib lub sijhawm, nws tseem yuav cuam tshuam cov load thaum dov.

5. Tshem tawm thiab tswj cov impurities ntawm qhov chaw ntawm cov khoom dov
Qhov no yog hais txog kev tshem tawm cov oxide raws sij hawm thiab zoo nyob rau sab hauv thiab sab nrauv ntawm cov kav dej capillary thiab barren thiab kev tswj ntawm re-oxidation ua ntej dov deformation. Nitrogen tshuab thiab borax txau kev kho mob nyob rau hauv lub puab qhov ntawm lub capillary raj, high-pressure dej descaling nyob rau hauv lub nkag ntawm lub dov raj thiab lub taag (txo) txoj kab uas hla tuaj yeem txhim kho thiab txhim kho qhov zoo ntawm sab hauv thiab sab nrauv.

Nyob rau hauv luv luv, muaj ntau yam uas cuam tshuam rau qhov zoo ntawm seamless steel raj, thiab lawv feem ntau ua ke cov nyhuv ntawm ntau yam. Yog li ntawd, cov ntsiab lus tseem ceeb uas tau hais los saum toj no yuav tsum tau tswj kom zoo. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem tswj tau qhov zoo ntawm seamless steel hlab thiab tsim kub dov seamless steel hlab nrog siab qhov tseeb, kev ua tau zoo thiab zoo heev.
