Cov kav dej tsis sib haum yog ib qho tseem ceeb hauv kev tsim kho kev lag luam thiab kev sib txuas lus hauv tsev. Vim tsis muaj seams nyob rau hauv kev tsim ntawm xws li qhov chaw, peb muaj peev xwm hais tias lawv yog cov feem ntau ruaj ntawm lawv hom. Raws li kev xyaum qhia, cov kav dej seamless yog qhov tseeb los ntawm kev ua kom muaj zog rau lub cev thiab kev ntxhov siab, thiab yog li ntawd muaj cov yam ntxwv ua haujlwm siab.

Scope of application

Raws li peb tau sau tseg lawm, cov khoom no yog cov yam ntxwv ntawm kev ua haujlwm siab. Nws yog vim cov khoom zoo no uas lawv tau siv rau hauv cov chaw uas yuav tsum muaj kev ntseeg siab dua. Piv txwv li, cov qauv tuab-walled ntawm cov khoom siv no yog siv thaum tso dej thiab cov kav dej. Kub dov seamless kav yog dav siv nyob rau hauv cov roj thiab roj kev lag luam thiab mechanical engineering. Tsis tas li ntawd, cov khoom no yog siv rau hauvkev siv pej xeem. Nws tseem tsim nyog sau cia tias feem ntau ntawm cov khoom tsim nyob rau hauv CIS lub teb chaws (xws li seamless yeeb nkab GOST 8732-78) raug xa mus rau ntau lub teb chaws Europe.

Ntau yam

Raws li phab ntsa tuab, cov khoom no tau muab faib ua ob hom:

  1. Thick-walled.
  2. Thin-walled.

Nyob rau hauv rooj plaub no, qhov dav ntawm phab ntsa ntawm thawj hom ntawm qhov sib txawv ntawm 12.5 txog 40.0 millimeters. Thin-walled yeeb nkab - seamless txias-tsim - muaj phab ntsa dav ntawm 6 mus rau 12.5 millimeters.

Raws li qhov tseeb ntawm kev tsim cov kab, cov kav dej no tuaj yeem muab faib ua cov khoom zoo tib yam thiab cov khoom siv siab. Qhov ntev ntawm cov hlau nws tus kheej tuaj yeem yog 4 txog 12.5 meters lossis ntau dua.

khoom

Ntau zaus, seamless kav yog tsim los ntawm high-strength alloy los yog carbon hlau. Ob qho khoom siv yog qhov txawv los ntawm kev ntseeg siab thiab kev ua haujlwm zoo. Ua tsaug rau qhov no, cov kav dej seamless muaj qhov tiv taus corrosion, tshuaj lom neeg thiab lwm yam tshuaj.

Nyob ntawm seb hom hlau twg tau siv rau hauv kev tsim cov khoom, cov kws txawj paub qhov txawv ntawm ntau hom seamless kav:

  1. Nrog cov qauv ntawm cov khoom siv kho tshuab.
  2. Nrog cov qauv ntawm cov tshuaj muaj pes tsawg leeg.
  3. Nrog normalization ntawm ob qho tib si (chemical thiab mechanical) yam ntxwv.
  4. Tsis hwm cov khoom thiab muaj pes tsawg leeg.

Los ntawm txoj kev, kev tsim khoom

cov no yog plaub. Nws tuaj yeem yog: forging, dov, nias lossis kos duab. Txawm li cas los xij, tsis muaj teeb meem kev tsim khoom siv li cas, cov khoom zoo li no yuav tsum muaj zog ntau npaum li qhov ua tau thiab tiv taus rau sab nraud aggressive yam.

Zaj lus

Yog li, cov kav dej seamless yog ib qho ntawm cov khoom siv ruaj khov thiab tiv taus siv hauv kev lag luam thiab kev sib txuas lus hauv nroog. Xws li kev siv ntau yam yog vim muaj kev ua haujlwm siab ntawm cov khoom no. Thiab qhov no, nyob rau hauv lem, yog ib tug tshwj xeeb seamless manufacturing txoj kev thiab siv cov feem ntau check steel qib - alloy thiab carbon.
