Ib qho kev lim dej lim dej zoo yog qhov tseem ceeb rau kev loj hlob thiab kev loj hlob ntawm txhua lub nroog. Hauv kev tsim kho thiab txij nkawm ntawmtus kav rau quav zistxoj kabs, xaiv cov kav dej tsim nyog thiab cov txheej txheem kev teeb tsa yog qhov tseem ceeb heev. Muab kauv submerged arc kav (swshaw (ssaw) tau dhau los ua kev txhim khu kev qha thiab cov kev daws teeb meem zoo rau cov lim dej. Lub hom phiaj ntawm cov blog no yog txhawm rau kom muaj teeb pom kev zoo thiab kev siv ntawm kauv submerged arc welded yeeb nkab hauv txhim kho cov lim dej.

Txheej txheem cauv ntawm kauv submerged arc Welded Yeeb:

Muab kauv submerged arc yeeb nkab, feem ntau yog hu ua kauv submerged arc welded yeeb nkab, yog tsim los ntawm cov hlau kub dov rau hauv kev kauv siv cov txheej txheem weld siv cov txheej txheem vuam. Cov kav dej no muaj cov qib siab ntawm rigidity, lub zog thiab corrosion tsis kam, ua rau lawv zoo tagnrho rau cov phiaj xwm tseem ceeb xws li cov dej phwj.

Qhov zoo ntawm SSAW cov yeeb nkab hauv cov ntawv thov lim dej:

1. Durabe: kauv submerged arc welded kav yog tsim los ntawm cov hlau zoo thiab muaj cov depability zoo heev. Lawv muaj lub zog los tiv thaiv kev hnyav hnyav thiab cov xwm txheej hnyav, ua kom muaj kev pabcuam lub neej ntev rau cov kav phwj tuaj.

2. Corrosion Kuj: Cov txheej txheem kub-dip galvanizing ntxiv rau ntawm kev tiv thaiv kab mob sib tua, ua rau nws muaj kev tiv thaiv. Cov cuab yeej no yog qhov tseem ceeb rau cov lim dej vim tias lawv feem ntau ntsib cov tshuaj lom neeg thiab ib puag ncig fais fab.

3. Qaug ua pov thawj tsim: tus kauv submerged arc Welded yeeb nkab yog tsim siv cov txheej txheem txuas ntxiv ua kom muaj cov txheej txheem ua pov thawj. Qhov yeeb yam no tiv thaiv ib qho kev nkag mus lossis xau dej, thiaj li txo qis kev sib kis hauv av thiab qhov xav tau kev kho tau kim.

4. Yooj Yim Thiab Kev Hloov Kho: Muab Kauv Khaub Ncaws Arc Welded Yeeb Nkab tuaj yeem tsim kom haum ntau yam diameters, ntev thiab nqes av, ua rau kev tsim qauv dej phwj. Lawv tuaj yeem yooj yim hloov kho kom hloov hauv av thiab kev taw qhia, ua kom cov dej ntws nrawm nrawm.

5. Nqi-ua hauj lwm: piv nrog cov dej phwj tso dej xws li pob zeb ua ke tuaj yeem muab cov nqi ntawm cov khoom lag luam tseem ceeb hauv kev teeb tsa thiab txij nkawm. Lawv lub teeb yuag txo cov nqi thauj khoom thiab lawv yooj yim rau kev txhim kho, yuav tsum tau ua haujlwm ua haujlwm. Tsis tas li ntawd, nws lub neej pabcuam ntev thiab kev saib xyuas tsawg kawg nkaus thiab kev saib xyuas tsawg kawg nkaus ua rau tus nqi mus ntev.

a. Cov txheej txheem Deagidation yog tsim raws li hauv qab no: FF: Nkaus tua cov hlau uas muaj cov khoom siv nitrogen khi rau hauv cov nyiaj muaj peev xwm khi muaj nitrogen (piv txwv li min lossis 0,015% soluble al). b. Tus nqi siab tshaj plaws rau Nitrogen tsis siv yog tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm 0,020% nrog tsawg kawg AL / N piv txog 2: 1, lossis yog tias muaj lwm cov n-khi cov khoom n-khi tam sim no. Cov n-khi cov ntsiab yuav tsum tau sau cia hauv daim ntawv tshuaj xyuas.

Cov ntawv thov ntawm ssaw kav hauv lim dej:

1. Cov kav dej phwj tuaj: SSAW cov kav dej feem ntau siv hauv kev tsim kho ntawm cov dej phwj tuaj yeem ua haujlwm hauv thaj chaw, kev lag luam thiab chaw lag luam. Lawv lub zog thiab corrosion tsis kam ua rau lawv xaiv zoo rau kev thauj cov dej tsis ntev dhau mus deb.

2. Cua daj cua dub ntws:SSAW KavTuaj yeem tswj hwm cov dej khov dej khov thiab tiv thaiv kev nyab xeeb hauv cov chaw hauv nroog. Lawv lub zog ua rau muaj kev hloov pauv ntawm cov dej loj ntawm cov dej ntawm cov dej siab.

3 Lawv txoj kev tawm tsam kom corrosive tshuaj thiab muaj peev xwm los lis cov kev ntsuas sib txawv ua rau lawv tsis muaj peev xwm xav tau ib puag ncig uas xav tau.

Hauv kev xaus:

Xaiv cov khoom siv yeeb nkab raug yog qhov tseem ceeb rau kev tsim kho zoo thiab saib xyuas ntawm koj cov dej phwj. Muab kauv submerged Arc Yeeb Nkab (SSAW) tau muaj pov thawj los ua tus nqi tsim nyog, ruaj thiab ntau yam lim dej hauv av. Nrog lawv zoo heev corrosion tsis kam, xau pov thawj tsim, thiab kev yoog raws li cov chaw sib txawv, cov kav dej tau ua kom muaj zog ntawm cov nroog. Kev siv kauv submerged arc welded kav dej hauv cov dej phwj dej hauv cov dej phwj tuaj yeem ua kom tau cov dej phwj kom tau raws li kev loj hlob ntawm txoj kev loj hlob.
