    Peb lub tuam txhab feem ntau koom nrog kev lag luam xa tawm ntawm seamless steel hlab,Tuam Tshoj Steel Tube, Suav SMLS, Seamless steel kav, Seamless steel tubes, SMLS, SMLS Tuam Tshoj, SMLS cov kav dej.

    Ob peb lub ntsiab qauv ntawm kub dov seamless steel raj ntau lawm
    1, Kub dov steel kav

    ua tus qauv tseem ceeb rau seamless steel yeeb nkab ntau lawm. Multi-stand nruam yeeb nkab dov tshuab.
    Piv nrog rau lwm cov qauv, qhov nruam dov zeb tau dhau los ua thawj qhov kev xaiv rau lub ntiaj teb loj seamless steel tube ntau lawm kev lag luam vim nws cov khoom zoo, siab tso zis, siab efficiency, thiab tsawg noj.
    2, 3 yob nruam yeeb nkab dov zeb

    qhib lub sijhawm tshiab ntawm kev nruam dov steel yeeb nkab tshuab
    Txij li thaum xyoo 2005, muaj ntau tshaj 20 teeb ntawm 3-rolling nruam mills uas tau tsim thiab tab tom tsim thoob ntiaj teb. Kev tsim kho ntawm cov dov mills no tau tsim lub sijhawm tshiab ntawm 3-yob txuas ntxiv dov steel yeeb nkab tshuab.
    3. Tsis siv neeg yeeb nkab dov tshuab, tseem hu ua Plug zeb
    Ntawm lawv, qhov loj thiab nruab nrab tsis siv neeg cov yeeb nkab dov mills tseem ua lub luag haujlwm tseem ceeb tom qab kev hloov pauv.
    4. Periodic yeeb nkab dov zeb, tseem hu ua Pilger zeb

    yog tsim rau zus tau tej cov nruab nrab thiab tuab phab ntsa loj thiab nruab nrab caliber steel kav. Nws yog ib qho ntawm cov qauv qub tshaj plaws hauv ntiaj teb
    Vim tias qhov ua tau zoo ntawm cov khoom siv qis thiab tsis zoo sab nrauv ntawm lub zeb no, nws cov nqi tsim khoom thiab cov khoom zoo yog qhov nyuaj rau kev sib tw nrog lwm cov mills. Feem ntau ntawm cov me me thiab nruab nrab-caliber mills tau raug tshem tawm. Loj-scale lub sij hawm lub raj dov zeb tseem muaj qhov zoo dua hauv kev tsim cov kab loj-ntev tuab-walled steel hlab, tshwj xeeb tshaj yog rau kev tsim cov loj-inch tuab-phab ntsa fais fab chaw nres tsheb. Periodic tube dov mills tseem yog ib txoj hauv kev zoo, yog li lawv khaws cia.
    5.Precision raj dov tshuab, 3-yob raj dov tshuab
    Lub precision raj dov tshuab tseem hu ua Accu2Roll raj dov tshuab, thiab 3-yob raj dov tshuab kuj hu ua Assel raj dov tshuab. Nws tseem yog seamless steel raj dov zeb nrog siab dov raug. Kev teeb tsa ntawm cov txheej txheem pem hauv ntej thiab nraub qaum yog qhov pib zoo ib yam li Accu2Roll raj zeb tsuas yog tias lub stretcher siv 3-yob cross-rolling.
    6. Lwm lub raj dov tshuab
    Tsuas yog rau Tuam Tshoj, extruders, loj-inch yeeb nkab jacking tshuab, thiab loj-inch skew dov thiab expanding machines muaj me ntsis kev loj hlob nyob rau hauv lwm lub teb chaws nyob rau hauv lub ntiaj teb no. Nyob rau hauv Suav teb, vim muaj kev loj hlob sai ntawm seamless steel yeeb nkab ntau lawm thiab qhov kev thov rau high-end khoom, kev tsim kho ntawm cov dov mills kuj tau tsim tshiab.

    Zoo siab txais tos tuaj xyuas peb lub tuam txhab, lub Hoobkas uas qhia ntau yam khoom uas yuav ua tau raws li koj qhov kev cia siab. Lub caij no, nws yooj yim mus xyuas peb lub vev xaib, thiab peb cov neeg ua haujlwm muag yuav sim lawv qhov zoo tshaj plaws los muab kev pabcuam zoo tshaj rau koj. Thov hu rau peb yog tias koj xav paub ntxiv. Peb lub hom phiaj yog los pab cov neeg siv khoom paub lawv lub hom phiaj. Peb tab tom ua haujlwm zoo los ua kom tiav qhov xwm txheej yeej-yeej.

    a.Ntxiv rau Q345A thiab Q345B qib, cov hlau yuav tsum muaj tsawg kawg yog ib qho ntawm cov khoom ua kom zoo zoo Al, Nb, V, thiab Ti. Raws li kev xav tau, tus neeg muag khoom tuaj yeem ntxiv ib lossis ntau cov khoom ua kom zoo zoo. Tus nqi siab tshaj plaws yuav tsum yog raws li tau teev tseg hauv cov lus. Thaum ua ke, Nb + V + Ti tsis ntau tshaj 0.22%b. Rau Q345, Q390, Q420 thiab Q46O qib, Mo + Cr tsis ntau dua 0.30%c. Thaum Cr thiab Ni ntawm txhua qib yog siv los ua cov khoom seem, cov ntsiab lus ntawm Cr thiab Ni yuav tsum tsis txhob siab dua 0.30%; thaum nws tsim nyog ntxiv, cov ntsiab lus yuav tsum ua kom tau raws li qhov yuav tsum tau ua hauv lub rooj lossis txiav txim siab los ntawm tus neeg muag khoom thiab tus neeg yuav khoom los ntawm kev sib tham.d. Yog tias tus neeg muag khoom tuaj yeem ua kom ntseeg tau tias cov ntsiab lus nitrogen ua tau raws li qhov yuav tsum tau ua hauv lub rooj, kev tshuaj xyuas cov ntsiab lus nitrogen yuav tsis ua. Yog tias Al, Nb, V, Ti thiab lwm yam hlau alloy nrog nitrogen fixation ntxiv rau cov hlau, cov ntsiab lus nitrogen tsis txwv. Cov ntsiab lus ntawm nitrogen fixation yuav tsum tau teev nyob rau hauv daim ntawv pov thawj zoo.e. Thaum siv tag nrho txhuas, tag nrho cov ntsiab lus txhuas Alt ≥ 0020%.

Hauv kev ntsuas tensile, cov qauv transverse lossis longitudinal tuaj yeem coj mus kuaj. Nyob rau hauv cov ntaub ntawv ntawm kev tsis pom zoo, tus qauv longitudinal yog siv los ua lub hauv paus rau kev txiav txim.c. Cov hlau uas muaj boron tuaj yeem ua rau normalize ua ntej quenching, thiab qhov normalizing kub yuav tsum tsis txhob siab tshaj nws quenching kub.d. Kev xa khoom raws li cov ntaub ntawv teev tseg los ntawm tus neeg thov. Thaum tus neeg thov tsis tau teev tseg, kev xa khoom tuaj yeem ua raws li ib qho ntawm cov ntaub ntawv.e. Thawj quenching ntawm titanium hlau nrog Ming Meng tuaj yeem hloov tau los ntawm normalizing.
