Qhov ntev hluav taws xob welded steel yeeb nkab siv nyob qhov twg niaj hnub no? Qhov no yog cov khoom lag luam uas niaj hnub no tau siv dav hauv ntau lub lag luam.

Daim ntawv thov

Raws li txoj cai, nws tau muab tso rau qhov chaw uas yuav tsum tau thauj cov roj av lossis cov kua dej uas muaj kev aggressiveness siab. Yog li ntawd, cov kav dej ntawm cov phiaj xwm no tuaj yeem pom hauv kev tsim kho tshuab, thaum tso cov cua sov sib txuas ntawm theem tseem ceeb.

Hlau hluav taws xob-welded longitudinal yeeb nkab yog siv hauv kev lag luam. Nws yog tsis yooj yim sua ua tsis tau nws nyob rau hauv cov roj ntau lawm, kev tsim kho ntawm scaffolding, nyob rau hauv kev tsim cov rooj tog los yog txawm cov khoom ua si. Nws versatility, kev ua tau zoo, zoo heev vuam peev xwm (nrog rau lub tsev vuam) tso cai rau nws siv nyob rau hauv domestic tej yam kev mob rau tsim thiab kho ntawm engineering networks.

Sizes

Hlau hluav taws xob-welded longitudinal kav, GOST uas muaj tus lej 10704-91, yog tsim nyob rau hauv ib qho ntev random rau ib txoj kab uas hla. Piv txwv li, nrog tus nqi ntawm lub tom kawg mus txog 0.3 cmCov khoom yuav tsum tsis txhob tsawg tshaj li 2 meters ntev, thiab yog hais tias qhov parameter no ntau tshaj 15.2 cm, ces qhov ntev yuav tsum tsis txhob yuav tsawg tshaj li 5 m. Kuj tseem muaj kev xaiv qhov ntev ntawm cov yeeb nkab ntev nyob rau hauv tej yam kev txwv rau ib tug muab txoj kab uas hla. Yog li, rau qhov ntsuas txog li 7 cm, qhov loj ntawm kab lus tuaj yeem sib txawv ntawm 5 txog 9 meters.

Production

Cov yeeb nkab zoo li cas yuav tsum muaj? Hlau hluav taws xob-welded longitudinal hloov kho thaum lub sij hawm tsim khoom yuav tsum muaj cov kev txwv uas ua tau raws li lub xeev cov cai rau cov khoom siv hauv ib cheeb tsam. Piv txwv li, cov kav dej rau cov roj thiab cov kav dej (lub cev) yog ua raws li GOST 20295-85. Lawv raug tsim los ntawm kev sib txuas ntawm hluav taws xob arc lossis hom kev sib cuag (tom kawg siv cov khoom siv hluav taws xob siab) nrog cov chav kawm sib txawv (ntawm K34 txog K60).

Rau cov khoom siv, cov khoom siv cua sov los yog kub-kuav los tiag steel (ntev lossis ib nrab ntsiag to) nrog C (carbon) cov ntsiab lus tsis ntau tshaj 0.2% los ntawm qhov hnyav yog siv. Nws cov nplooj ntawv yog twisted rau hauv ib lub yeeb nkab, tom qab uas cov npoo ntawm cov nplooj ntawv yog rhuab los ntawm tam sim no thiab nyem los ntawm yob (electrode rings). Qhov ceev ntawm cov txheej txheem no ntawm cov tshuab tshwj xeeb tuaj yeem ua tau siab heev (ntau tshaj li kaum meters ntawm vuam ib feeb, nyob ntawm phab ntsa thickness). Kev ua haujlwm yuav luag ib txwm nrog los ntawm kev txiav cov khoom ntawm qhov xav tau ntev siv cov cuab yeej txiav.

Steel welded longitudinally welded yeeb nkab tuaj yeem kho cua sov ob qho tib si raws li qhov ntev thiab tsuas yog raws qhov vuam. Nyob ntawmlub hauv paus hlau ntawm cov khoom yog tsis pub muaj kev poob cev qhev, flaws, tawg, sunsets thiab delaminations. Deg qhov tsis xws luag ntawm ib qho kev lees paub yuav tsum tsis txhob raug kho los ntawm kev sib tsoo (tsuas yog sib tsoo) thiaj li tswj tau qhov yuav tsum tau ua ntawm cov khoom lag luam ntseeg tau. Cov yeeb nkab welds yuav tsum tsis txhob muaj qhov tsis muaj kev nkag mus, tawg, pores, fistulas, slag inclusions uas tuaj rau saum npoo.

Tus nqi

Ntev npaum li cas welded steel kav? Tus nqi rau lawv, nyob ntawm qhov chaw tsim khoom, qib steel, txoj kab uas hla thiab phab ntsa tuab, tuaj yeem nyob ntawm 32 txog 45-48 txhiab. Thaum muas, koj yuav tsum nco ntsoov xyuam xim rau kev ua raws li GOST, vim hais tias nyob rau hauv nws lub moj khaum, cov khoom dhau qhov kev ntsuam xyuas tsim nyog, nrog rau kev sib koom ntawm cov viscous tivthaiv, cuam tshuam dabtsi yog khoov ntawm qhov sib txawv ntawm qhov kub thiab txias, tensile, ovality ntawm tsab xov xwm, qhov ntev ntawm nws. sib txawv, qhov zoo ntawm cov hlau hauv welded sib koom, thiab lwm yam.

Cov ntaub ntawv hais txog cov khoom twg uas yuav npaj yuav tuaj yeem pom los ntawm lub thwj rau ntawm cov yeeb nkab. Nws yuav tsum tau affixed ntawm qhov deb ntawm 10-150 cm los ntawm ib qho kawg, cim nrog cov xim thiab suav nrog lub xyoo ntawm kev tsim khoom, cov ntaub ntawv tswj kev, qib steel, tus kheej yeeb nkab (batch) tus lej, cov cim lag luam ntawm cov chaw tsim khoom.
