Thaum lub sij hawm installation thiab tso cov txheej txheem platform ntawm galvanized steel grating, nws yog feem ntau ntsib hais tias pipelines los yog cov khoom yuav tsum tau mus dhau lub steel grating platform vertically. Txhawm rau kom cov khoom siv hauv cov kav dej kom dhau los ntawm lub platform smoothly, nws yog feem ntau yuav tsum tau txiav txim siab qhov chaw thiab qhov loj ntawm qhov qhib thaum lub sij hawm tsim, thiab cov chaw tsim khoom steel grating yuav ua raws li kev tsim khoom. Cov txheej txheem ntawm kev tsim khoom lag luam ua ntej yuav tsum muaj lub tuam tsev tsim qauv steel grating los sib txuas lus thiab sib pauv cov ntaub ntawv nrog lub tuam tsev tsim qauv steel, cov chaw muab khoom siv, thiab cov chaw soj ntsuam thiab kos duab. Vim muaj ntau yam cuam tshuam nrog, thiab qhov loj thiab qhov chaw ntawm cov cuab yeej muaj qee yam tsis paub tseeb. Thaum lub sij hawm installation thiab kev tsim kho, nws yog feem ntau yog hais tias lub customized reserved qhov tsis tau raws li qhov xav tau ntawm qhov chaw. Nyob rau hauv qhov kev pom ntawm qhov teeb meem no, txhawm rau kom ntseeg tau tias cov txiaj ntsig ntawm cov hlau grating thiab txhim kho kev tsim thiab kev ua haujlwm ntawm cov hlau grating. Hauv kev tsim qauv tam sim no thiab cov txheej txheem tsim khoom, qee qhov me me txoj kab uas hla uas nws txoj haujlwm nyuaj los txiav txim siab feem ntau tsis kho thiab ua tiav. Hloov chaw, cov txheej txheem ua haujlwm thib ob xws li qhib qhov chaw, txiav, vuam, thiab sib tsoo tau ua raws li qhov xwm txheej tam sim no thaum lub sijhawm teeb tsa thiab kev tsim kho ntawm cov hlau grating.
Raws li cov khoom siv tshiab, galvanized steel grating yog nce dav siv. Galvanizing tau dhau los ua ib qho tseem ceeb los tiv thaiv corrosion rau steel gratings, tsis tsuas yog vim zinc tuaj yeem tsim cov txheej txheem tiv thaiv ntom ntom ntawm cov hlau, tab sis kuj vim tias zinc muaj kev tiv thaiv cathodic. Thaum cov galvanized steel grating raug thauj mus rau qhov chaw, kev ua haujlwm thib ob thiab vuam qee zaum yuav tsum tau ua vim qhov xav tau rau kev teeb tsa. Lub xub ntiag ntawm zinc txheej coj tej yam nyuaj rau lub vuam ntawm galvanized steel grating.
Kev soj ntsuam ntawm weldability ntawm galvanized steel grating
Galvanized steel grating yog los tiv thaiv qhov saum npoo ntawm steel grating los ntawm corrosion thiab ncua nws cov kev pab cuam lub neej. Ib txheej ntawm cov hlau zinc yog plated nyob rau saum npoo ntawm cov hlau grating, thiab qhov saum npoo ntawm galvanized steel grating yuav ua paj zoo li paj. Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no: ① kub-dip galvanized ntawv; ② electrogalvanized steel ntawv. Lub melting point ntawm zinc yog 419 ℃ thiab boiling point yog 907 ℃, uas yog deb tshaj qhov melting point ntawm hlau 1500 ℃. Yog li ntawd, thaum lub sij hawm vuam txheej txheem, galvanized txheej melts ua ntej cov khoom niam txiv. Tom qab kev soj ntsuam saum toj no, cov khoom siv kho tshuab thiab lub cev muaj zog ntawm cov ntawv galvanized yog tib yam li cov ntawv carbon steel zoo tib yam. Qhov txawv tsuas yog tias muaj txheej txheej galvanized rau ntawm qhov chaw ntawm galvanized steel grating. Vuam txheej txheem ntawm galvanized steel grating
(1) Kev tuav arc vuam
Txhawm rau txo cov pa luam yeeb ntawm vuam thiab tiv thaiv cov cim ntawm vuam tawg thiab qhov pores, zinc txheej ze ntawm qhov zawj yuav tsum tau muab tshem tawm ua ntej vuam. Txoj kev tshem tawm tuaj yeem yog nplaim taws ci lossis sandblasting. Lub hauv paus ntsiab lus ntawm kev xaiv vuam rods yog tias cov khoom siv ntawm cov vuam hlau yuav tsum nyob ze li sai tau rau cov khoom siv niam txiv, thiab cov ntsiab lus ntawm silicon nyob rau hauv vuam qws nplaim hlau yuav tsum tau tswj hauv qab 0.2%. Rau cov pa roj carbon tsawg galvanized steel grating, J421 / J422 lossis J423 vuam rods yuav tsum tau siv ua ntej. Thaum vuam, sim siv lub arc luv luv thiab tsis txhob cia lub arc viav vias los tiv thaiv kev nthuav dav ntawm thaj tsam molten ntawm zinc txheej, xyuas kom muaj kev tiv thaiv corrosion ntawm lub workpiece thiab txo cov pa luam yeeb.
(2) Metallurgical electrode gas shielded vuam siv CO2 roj shielded vuam los yog sib xyaw roj shielded vuam xws li Ar + CO2, Ar + 02 rau vuam. Lub shielding gas muaj qhov cuam tshuam tseem ceeb ntawm Zn cov ntsiab lus hauv vuam. Thaum siv cov ntshiab CO2 lossis CO2 + 02, Zn cov ntsiab lus hauv vuam yog siab dua, thaum siv Ar + CO2 lossis Ar + 02, Zn cov ntsiab lus hauv cov vuam yog qis dua. Qhov tam sim no muaj me ntsis cuam tshuam rau Zn cov ntsiab lus hauv vuam. Raws li cov vuam tam sim no nce, Zn cov ntsiab lus hauv cov vuam qis me ntsis. Thaum siv roj shielded vuam rau vuam galvanized steel grating, vuam fume yog loj dua li phau ntawv arc vuam, yog li yuav tsum tau them tshwj xeeb mloog kom tso pa tawm. Cov yam tseem ceeb uas cuam tshuam rau tus nqi thiab muaj pes tsawg leeg ntawm cov fume yog tam sim no thiab shielding gas. Qhov loj dua tam sim no, los yog ntau dua cov ntsiab lus ntawm C02 lossis 02 hauv cov roj tiv thaiv, qhov loj dua qhov vuam fume, thiab Zn0 cov ntsiab lus hauv cov pa taws kuj nce. Qhov siab tshaj plaws Zn0 cov ntsiab lus tuaj yeem ncav cuag li 70%. Nyob rau hauv tib lub vuam specifications, qhov tob ntawm galvanized steel grating yog ntau dua li ntawm cov tsis-galvanized steel grating.
