Kauv Seamless Welded Yeeb Nkab
Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm cov khoom siv zoo tshaj plaws thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm welds tau raug txhim kho tas li, thiab ntau yam thiab cov ntsiab lus ntawm welded steel kav tau nce. Seam lub steel yeeb nkab. Welded steel kav yog muab faib ua ncaj seam welded kav thiab kauv welded kav raws li daim ntawv ntawm welds. Kev faib tawm los ntawm txoj kev tsim khoom: txheej txheem kev faib tawm-arc welded yeeb nkab, tsis kam welded yeeb nkab, (siab zaus, tsawg zaus) roj welded yeeb nkab, rauv welded yeeb nkab.
Cov kab me me welded kav yog welded los ntawm ncaj seam, thaum loj txoj kab uas hla welded kav feem ntau muab kauv welded. Raws li cov duab ntawm qhov kawg ntawm cov yeeb nkab steel, nws muab faib ua puag ncig welded yeeb nkab thiab tshwj xeeb-puab (square, rectangular, thiab lwm yam) welded yeeb nkab; Raws li cov ntaub ntawv sib txawv thiab siv, nws tau muab faib ua cov dej mining Conveying welded steel kav, galvanized welded steel kav rau cov dej tsis tshua muaj siab conveying, hluav taws xob welded steel kav rau siv conveyor rollers, thiab lwm yam. , txheeb los ntawm sab nraud * phab ntsa thickness los ntawm me me mus rau loj.
Cov khoom siv feem ntau siv rau cov kav dej welded yog: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni101Nb, lwm.
Cov blanks siv rau welded steel kav yog steel daim hlau los yog sawb hlau, uas tau muab faib ua rau hauv lub cub tawg welded kav, hluav taws xob welded (kuj welded) kav thiab tsis siv neeg arc welded kav vim lawv cov txheej txheem vuam sib txawv. Vim nws cov ntaub ntawv sib txawv, nws tuaj yeem muab faib ua ob hom: ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab. Vim nws qhov kawg zoo, nws tau muab faib ua puag ncig welded yeeb nkab thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded yeeb nkab. Welded kav tau muab faib ua ntau hom hauv qab no vim lawv cov khoom sib txawv thiab siv:
GB / T3091-2008 (Welded steel kav rau kev thauj mus los ntawm cov dej tsis tshua muaj siab): Feem ntau yog siv los thauj dej, roj, huab cua, roj, cua sov dej lossis chav dej thiab lwm yam dej siab thiab lwm yam. Nws cov khoom sawv cev yog: Q235A qib steel.
GB/T14291-2006 (Welded Steel Pipe for Mining Fluid Transport): Feem ntau yog siv rau txoj hlua ncaj nraim welded steel kav rau kuv cov cua siab, kua dej, thiab cov pa tawm roj. Nws cov khoom sawv cev yog Q235A, Qib B steel.
GB / T12770-2002 (Stainless steel welded steel yeeb nkab rau cov khoom siv tshuab): Feem ntau yog siv rau cov tshuab, tsheb, tsheb kauj vab, rooj tog zaum, tsev so thiab tsev noj mov kho kom zoo nkauj thiab lwm yam khoom siv thiab cov khoom siv. Nws cov ntaub ntawv sawv cev yog 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, thiab lwm yam.

Tsis tas li ntawd, welded stainless hlau kav rau kho kom zoo nkauj (GB / T 18705-2002), stainless hlau welded kav rau architectural kho kom zoo nkauj (JG / T 3030-1995), thiab welded steel kav rau tshav kub exchangers (YB4103-2000).
Longitudinal welded yeeb nkab muaj cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis thiab kev loj hlob sai. Lub zog ntawm kauv welded kav feem ntau yog siab tshaj qhov ncaj seam welded kav. Lub qhov khoob khoob tuaj yeem siv los tsim cov kav dej welded nrog cov yeeb nkab loj dua, thiab lub billet nrog tib qhov dav kuj tuaj yeem siv los tsim cov kav dej nrog cov yeeb nkab sib txawv. Tab sis piv nrog cov yeeb nkab ncaj seam ntawm tib qhov ntev, qhov ntev vuam yog nce los ntawm 30-100%, thiab cov khoom ceev yog qis dua.
Loj txoj kab uas hla los yog tuab welded kav feem ntau yog ua ncaj qha los ntawm steel blanks, thaum me me welded kav thiab nyias-phab ntsa welded kav tsuas yog yuav tsum tau welded ncaj qha los ntawm steel strips. Tom qab ntawd tom qab polishing yooj yim, kos duab zoo.
Ntxiv: Cov yeeb nkab welded yog welded nrog sawb hlau, yog li nws tsis siab npaum li cov yeeb nkab seamless.
