Peb cov khoom muaj feem xyuam
SAWL Manufacturing Methods
Phaj xaiv thiab npaj → Txiav thiab ntug Milling → Sib sau → Seaming thiab pre-welding → Sab hauv thiab sab nrauv vuam → vuam seam soj ntsuam → Ncaj, Txias Expansion thiab txiav mus rau ntev → Thaum tshav kub kub kho → nto kho thiab tiv thaiv → zaum kawg soj ntsuam thiab ntim
Phaj xaiv thiab npaj
Kev xaiv cov khoom siv hlau hlau uas tsim nyog, feem ntau muaj zog carbon steel lossis alloy steel phaj.
Cov phaj hlau yuav tsum tau kho qhov chaw kom tshem tawm xeb, roj, thiab lwm yam impurities ua ntej tsim khoom.
Txiav thiab Ntug Milling
Txiav cov hlau phaj: Txiav cov hlau daim hlau mus rau qhov loj raws li txoj kab uas hla ntawm cov yeeb nkab steel yuav tsum tau ua.
Ntug milling: siv lub tshuab ntug milling, tshem tawm burrs thiab zoo ntug zoo.
Kev tsim
Lub tiaj tiaj steel phaj yog khoov los ntawm lub tshuab dov kom nws maj mam tsim rau hauv qhov qhib cylindrical.Cov txheej txheem tsim feem ntau yog JCOE.
Seaming thiab pre-welding
Siv lub pre-welding seamer, seam, thiab pre-welding yog ua.
Pre-welding ntawm qhov kawg ntawm daim hlau los txhim kho cov duab thiab xyuas kom meej qhov sib koom ua ke ntawm cov hlab thaum lub sij hawm tseem ceeb ntawm cov txheej txheem vuam.
Internal thiab External Seam Vuam
Cov sab ntev (longitudinal seams) ntawm cov yeeb nkab yog welded siv cov txheej txheem submerged arc vuam.Cov kauj ruam no feem ntau yog ua ib txhij nyob rau hauv thiab sab nraum cov yeeb nkab.
Submerged arc vuam yog nqa tawm nyob rau hauv ib puag ncig los yog ib puag ncig ib puag ncig qhov chaw weld yog npog nrog ntau cov flux los tiv thaiv oxidation thiab ua kom lub vuam huv.
Vuam Seam Inspection
Tom qab ua tiav qhov vuam, qhov vuam yog qhov muag pom thiab tsis muaj kev puas tsuaj (xws li X-ray lossis kuaj ultrasonic) kom ntseeg tau tias cov vuam tsis muaj qhov tsis xws luag thiab ua tau raws li cov qauv zoo.
Straightening, Txias Expansion thiab txiav kom ntev
Siv lub tshuab ua kom ncaj, ncaj cov yeeb nkab steel.Xyuas kom meej tias qhov ncaj ntawm cov yeeb nkab steel ua tau raws li tus qauv yuav tsum tau ua
Nthuav cov yeeb nkab steel los ntawm txoj kab uas hla expanding tshuab kom ua tiav txoj kab uas hla thiab tshem tawm kev ntxhov siab.
Txiav cov yeeb nkab steel rau hauv qhov ntev raws li cov neeg siv khoom xav tau.
Kev kho cua sov
Yog tias xav tau, cov hlab ntsha raug kho kom sov, xws li normalized lossis annealed, los kho cov khoom siv hluav taws xob ntawm cov hlab ntsha thiab txhim kho toughness thiab lub zog.
Kev kho deg thiab kev tiv thaiv
Txheej kev kho mob, xws li cov tshuaj tiv thaiv corrosion, yog siv rau saum npoo ntawm cov kav dej steel los txhim kho lawv cov kev tiv thaiv corrosion thiab kev pab cuam lub neej.
Kev soj ntsuam zaum kawg thiab ntim
Tom qab ua tiav tag nrho cov txheej txheem fabrication, qhov kawg seem thiab kev soj ntsuam zoo yog ua los xyuas kom meej tias cov khoom raws li specifications.Kev ntim khoom tsim nyog yog ua tiav hauv kev npaj rau kev xa khoom xa tuaj.
