Cov yeeb nkab steel nrog welds yog muab faib rau hauv ib lub kauv txheeb ze rau lub axis ntawm lub cev yeeb nkab. Feem ntau yog siv los ua kev thauj mus los, cov kav dej, thiab qee cov kav dej. Khoom specifications: sab nraud txoj kab uas hla 300 ~ 3660mm, phab ntsa thickness 3.2 ~ 25.4 hli.
Cov yam ntxwv ntawm kauv welded yeeb nkab ntau lawm yog:
(1) Cov kav dej uas muaj ntau yam txheej sab nraud tuaj yeem tsim los ntawm cov strips ntawm tib qhov dav;
(2) Cov yeeb nkab muaj qhov ncaj ncaj thiab meej qhov ntev. Sab hauv thiab sab nraud kauv welds nce rigidity ntawm cov yeeb nkab lub cev, yog li tsis tas yuav tsum tau sizing thiab straightening txheej txheem tom qab vuam;
(3) Yooj yim kom paub siv tshuab, automation, thiab kev tsim khoom tas mus li;
(4) Piv nrog rau lwm cov cuab yeej ntawm cov nplai zoo sib xws, nws muaj qhov me me, kev ua haujlwm hauv av tsawg thiab kev nqis peev, thiab kev tsim kho sai dua;
(5) Muab piv nrog cov seam ncaj welded kav ntawm tib qhov loj, qhov vuam seam ib chav tsev ntev ntawm cov yeeb nkab yog ntev dua, yog li cov khoom tsim tau qis dua.

Cov txheej txheem ntau lawm ntws ntawm kauv welded yeeb nkab:
Cov ntaub ntawv raw ntawm kauv welded kav muaj xws li strips thiab daim hlau. Lub phaj yog siv thaum lub thickness yog siab tshaj 19mm. Thaum siv cov strips, txhawm rau xyuas kom cov khoom siv txuas ntxiv thaum lub pob tw vuam ntawm lub hauv ntej thiab nram qab coils, lub voj voog tuaj yeem siv tau, lossis siv lub tshuab ya vuam trolley tuaj yeem siv rau kev sib txuas ntawm pob tw. Tag nrho cov khoom npaj ua haujlwm los ntawm uncoiling mus rau lub taub qab vuam tuaj yeem ua raws li txoj kev ntawm ya vuam trolley. Ua tiav thaum lub sijhawm txav mus los. Thaum tus Tsov tus tw ntawm lub pem hauv ntej sawb hlau yog ntes tau los ntawm lub rear clamp ntawm lub taub qab vuam tshuab, lub trolley yog rub rau pem hauv ntej ntawm tib ceev raws li lub forming thiab pre-welding tshuab. Tom qab lub pob tw welding tiav lawm, lub nraub qaum yog tso tawm thiab lub trolley rov qab los ntawm nws tus kheej. mus rau qhov chaw qub. Thaum siv daim hlau, ib daim hlau hlau yuav tsum tau pob tw-welded rau hauv ib lub strips sab nraum cov kab khiav haujlwm, thiab tom qab ntawd xa mus rau cov txheej txheem kev khiav hauj lwm kom pob tw-welded thiab txuas nrog lub tsheb welding ya. Butt welding yog ua los ntawm kev siv tsis siv neeg submerged arc vuam, uas yog ua nyob rau sab hauv ntawm cov yeeb nkab. Cov cheeb tsam uas tsis tau nkag mus yog tsim thiab ua ntej welded, thiab tom qab ntawd kho ntawm cov yeeb nkab sab nrauv, thiab tom qab ntawd cov welds yog welded sab hauv thiab sab nraud. Ua ntej lub sawb nkag mus rau hauv lub tshuab tsim, lub ntug ntawm lub sawb yuav tsum tau pre-bent mus rau ib tug tej yam curvature raws li cov yeeb nkab txoj kab uas hla, phab ntsa thickness, thiab txoj kev lub kaum sab xis, thiaj li hais tias lub deformation curvature ntawm ntug thiab nruab nrab ib feem tom qab sib sau. raws li kev tiv thaiv "xyoob" tsis xws luag ntawm protruding weld cheeb tsam. Tom qab pre-bending, nws nkag mus rau hauv lub kauv qub rau kev tsim (saib kauv forming) thiab pre-welding. Txhawm rau txhim kho cov khoom tsim tau, ib txoj kab sib sau thiab ua ntej vuam feem ntau yog siv los ua kom haum rau ntau qhov sib txuas hauv thiab sab nraud. Qhov no tuaj yeem tsis tsuas yog txhim kho qhov zoo ntawm welds tab sis kuj nce ntau lawm. Pre-welding feem ntau siv shielded gas arc vuam los yog high-frequency kuj welding nrog ceev vuam ceev, thiab tag nrho-ntev welding. Qhov no vuam siv ntau tus ncej tsis siv neeg submerged arc vuam.

Txoj kev loj hlob tseem ceeb ntawm kauv welded yeeb nkab ntau lawm yog vim hais tias cov kabmob siab ntawm cov kav dej tau nce ib hnub dhau ib hnub, kev siv cov xwm txheej tau dhau los ua hnyav zuj zus, thiab kev pabcuam lub neej ntawm cov kav dej yuav tsum tau txuas ntxiv kom ntau li ntau tau, yog li cov lus qhia tseem ceeb ntawm txoj kev loj hlob. spiral welded kav yog:
(1) Ua cov kav dej loj-txheej tuab-walled los txhim kho kev ua haujlwm siab;
(2) Tsim thiab tsim cov yeeb nkab steel hlau tshiab, xws li ob txheej txheej kauv welded kav, uas yog welded rau hauv ob txheej yeeb nkab nrog sawb hlau ib nrab ntawm cov yeeb nkab phab ntsa. Tsis tsuas yog lawv lub zog siab dua li cov kav dej ib txheej ntawm tib lub thickness, tab sis lawv yuav tsis ua rau kev puas tsuaj;
(3) Tsim cov hom hlau tshiab, txhim kho cov txheej txheem ntawm cov txheej txheem smelting, thiab dav siv kev tswj cov dov thiab tom qab dov pov tseg cov txheej txheem kev kho cua sov kom txuas ntxiv txhim kho lub zog, toughness, thiab vuam kev ua tau zoo ntawm cov yeeb nkab lub cev;
(4) Siv zog tsim cov kav dej coated. Piv txwv li, txheej txheej sab hauv ntawm cov yeeb nkab nrog cov txheej txheem tiv thaiv tsis tuaj yeem tsuas yog txuas ntxiv lub neej kev pab cuam, tab sis kuj txhim kho qhov smoothness ntawm sab hauv phab ntsa, txo cov kua dej sib txhuam, txo cov wax thiab av nkos, txo cov yeeb nkab. ntxuav lub sij hawm, thiab txo kev txij nkawm.
