Thaum lub sij hawm installation thiab tso cov txheej txheem platform ntawm galvanized steel grating, nws yog feem ntau ntsib hais tias cov kav dej los yog cov cuab yeej yuav tsum tau mus dhau lubsteel gratingplatform 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 tsim ua ntej yuav tsum muaj kev sib txuas lus ntau thiab cov ntaub ntawv sib pauv ntawm steel grating tsim department thiab steel qauv tsim department, cov khoom muab kev pab thiab kev soj ntsuam thiab daim ntawv qhia department. Vim muaj ntau yam muaj feem cuam tshuam nrog, muaj qee qhov tsis paub tseeb ntawm qhov loj thiab qhov chaw ntawm cov khoom siv tam sim no. Thaum lub sij hawm installation, nws yog feem ntau yog hais tias lub customized reserved qhov yuav tsis tau raws li qhov xav tau ntawm qhov chaw. Raws li qhov xwm txheej no, txhawm rau kom ntseeg tau tias cov txiaj ntsig ntawm steel gratings thiab txhim kho cov qauv tsim thiab kev ua haujlwm ntawm cov hlau gratings, nyob rau hauv cov txheej txheem tsim thiab tsim khoom tam sim no, feem ntau hais lus, qee qhov nrog cov kab me me uas nyuaj rau kev txiav txim siab tsis raug kho thiab ua tiav, tab sis raug hloov los ntawm cov txheej txheem ua haujlwm thib ob xws li qhib qhov chaw, txiav, vuam, thiab sib tsoo raws li qhov xwm txheej tam sim no ntawm kev tsim kho steel.
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 yog qee zaum yuav tsum 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 gratings
Galvanized steel gratings yog coated nrog ib txheej ntawm hlau zinc rau ntawm qhov chaw ntawm cov hlau grating los tiv thaiv corrosion ntawm cov hlau grating thiab txuas nws lub neej kev pab cuam. Qhov saum npoo ntawm galvanized steel grating yuav yog paj-puab. 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 lub boiling point yog 907 ℃, uas yog deb tshaj lub melting point ntawm hlau, 1500 ℃. Yog li ntawd, thaum lub sij hawm vuam txheej txheem, galvanized txheej thawj melts cov khoom niam txiv. Tom qab kev soj ntsuam saum toj no, cov khoom siv kho tshuab thiab lub cev ntawm cov ntawv galvanized yog tib yam li cov ntawv carbon steel zoo tib yam. Qhov txawv tsuas yog tias muaj zinc txheej rau ntawm qhov chaw ntawm galvanized steel grating. Cov txheej txheem vuam 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 welding rods yog tias txhua yam khoom ntawm cov hlau vuam yuav tsum nyob ze li sai tau rau cov khoom siv niam txiv, thiab cov ntsiab lus ntawm silicon nyob rau hauv txhua hnub vuam pas nrig molten hlau yuav tsum tau tswj hauv qab 0.2%. Rau cov pa roj carbon tsawg daim iav zinc steel grating, J421/422 lossis J423 vuam rods yuav tsum tau siv ua ntej. Thaum vuam, sim siv lub arc luv luv thiab tsis txhob viav vias arc los tiv thaiv kev nthuav dav ntawm thaj tsam molten ntawm txheej txheej galvanized, xyuas kom muaj kev tiv thaiv corrosion ntawm lub workpiece thiab txo cov pa luam yeeb.
(2) Hlau arc 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 cov roj shielded vuam rau vuam galvanized steel grating, vuam fume yog loj dua li ntawm 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 feem ntau yog tam sim no thiab cov roj tiv thaiv. Qhov loj dua qhov tam sim no, lossis ntau dua cov ntsiab lus CO2 lossis O2 hauv cov pa tiv thaiv, qhov loj dua qhov vuam fume, thiab ZnO cov ntsiab lus hauv fume kuj nce. Qhov siab tshaj plaws ZnO cov ntsiab lus tuaj yeem ncav cuag li 70%. Nyob rau hauv tib lub vuam specifications, qhov tob tob ntawm galvanized steel grating yog ntau dua li cov uas tsis yog-galvanized steel grating.
