1. Cov txheej txheem pom zoo rau kev ua tiav kev lees txais ntawm ncaj me steel kav hlau yuav ua raws li cov qauv khoom lag luam.
2. Kev SEAM cov qauv siv hlau ncaj qha yuav ua raws cov qauv cov khoom lag luam, suav nrog kev tshuaj xyuas cov khoom, ntsuas qhov chaw thiab txoj kev xeem. Nrog kev pom zoo ntawm tus neeg yuav khoom, kub- rewed seamless steel kav yuav raug kuaj raws li tus naj npawb ntawm cov hauv paus hniav.
3. Yog tias muaj cov khoom uas tsis ua tau raws li cov qauv ntawm cov khoom lag luam, thiab ob chav kuaj yuav tsum tau xaiv, thiab ob chav qauv yuav tsum tau raug xaiv los ntawm ncaj me steel kav hlau kav mus rau recheck cov khoom tsis muaj peev xwm. Yog hais tias tus re - soj ntsuam cov txiaj ntsig tsis tau raws li cov qauv, cov pob ntawm cov leeg ncaj leeg steel kav yuav tsis raug xa mus.
4. Kev SEAM steel kav hlau uas tsis tau raws cov qauv (suav nrog cov khoom lag luam uas yuav tsum tau ua raws li cov qauv thiab tsis pub dhau los ntawm cov qauv thiab cov kev kho tshiab yuav tsum tsis pub tshaj ob zaug).
5. Yog tias tsis muaj cov txheej txheem tshwj xeeb hauv cov qauv khoom, cov tshuaj lom neeg muaj pes tsawg leeg ntawm txoj kab ncaj me steel yuav raug lees txais raws li cov muaj pes tsawg leeg.
Dab tsi yog qhov sib txawv ntawm ncaj me steel steel kav thiab siab - zaus ncaj seam steel kav?
Ib txoj hlua hlau welded steel nrog tsuas yog ib qho ntev weld yog ib txoj ncaj welded steel yeeb nkab. Raws li cov kev cai ntawm GB / 9711.1, txoj kab uas hla ntawm txoj ncaj welded steel yeeb yog 180 degree, thiab muaj peev xwm muaj ob leeg leeg leeg steel kav hlau uas yog tib yam.
Kev Seam Cov Kav Hlau Ncaj Nraim tuaj yeem faib ua Jcoe Ncaj Cov Kav Dej Ncaj thiab dov ncaj Seam Steel Kav hlau kav raws li cov txheej txheem ntau lawm.
Siab - zaus ncaj ncaj rau, hluav taws xob ncaj ncaj rau, thiab lwm yam. Siab - zaus ncaj seam steel kav siv lub siab {4 4}} lub sij hawm} Lub sij hawm fort extrusion ntawm ob qho kawg ntawm cov hlau phaj. Nws yog qhov tseeb hluav taws xob pob tw pob qij txha sib koom ua ke. Nrog kub - rolled coils li cov ntaub ntawv raw, cov phab ntsa tuab ntawm cov nplais Seam Steel kav tuaj yeem tswj tau ntawm txog ± 0. Lub 2 hli cov yeeb nkab xaus tau raws li US APL txheem lossis GB / T 9711.1 tus qauv. Cov yeeb nkab kawg yog txiav thiab lub tsheb thauj mus los ntev yog tsau. Nyob rau hauv xyoo tsis ntev los no, ERW steel kav tau siv dav siv raws li cov hlau loj uas cov phiaj xwm loj thiab cov phiaj xwm hauv nroog ntawm cov roj av roj. Ntawm tam sim no, siab - zaus los ntawm cov kav dej ncaj qha steel kav rau 60% ntawm lub ntiaj teb cov kav hlau.
Ob npaug {{{0} ated submered arc ncaj seam steel kav kuj tseem ncaj seam steel kav. Submerged Arc Vuam Ncaj Quav Steel Kav Hlau txais yuav Jelbe Txias Siv Rau Weld, thiab Granular Flux yog siv rau Submerged Arc. Cov txheej txheem ntau lawm ntawm submered arc vuam ncaj seam steel kav yog hloov tau thiab tuaj yeem tsim cov kev qhia tshwj xeeb ntawm 325 ~ 1420 hli. Nws ua tau raws li cov yeeb ncuab thoob ntiaj teb rau cov yeeb nkab steel hlau, thaum siab} zaus ncaj cov nplais steel kav yog feem ntau yog siv hauv kev tsim khoom lag luam hauv tsev.
Siab - zaus} zaus ncaj seam steel kav hlau feem ntau hu ua thawj cov kav hlau. Lub npe ntawm kev lag luam sib txawv ntawm submerged arc vuam ncaj seam steel kav hlau lossis thermal expir steel kav hlau, thiab lawv cov npe feem ntau tsis meej pem.
Cov ntsiab lus saum toj no yog qhia rau koj dab tsi yog txoj hlua khi ncaj ncaj. Kuv vam tias kev nyeem cov lus no tuaj yeem pab koj. Ua tsaug rau koj nyeem ntawv. Thov txuas ntxiv ua tib zoo mloog. Pom koj lwm zaus.
