Dab tsi yog cov kev cai ib puag ncig rau huab cua-resistant phaj vuam?

Dab tsi yog cov kev cai ib puag ncig rau huab cua-resistant phaj vuam? Weathering board muaj cov yam ntxwv ntawm toughness, yas extension, sib sau, vuam, corrosion, kub kub thiab qaug zog ntawm tshav kub-resistant cam khwb cia hlau. Kev laus tiv thaiv yog 2 mus rau 8 npaug ntawm cov pa roj carbon zoo tib yam, thiab cov tshuaj txau yog 1.5 txog 10 npaug ntawm cov pa roj carbon zoo tib yam. Nws tuaj yeem siv tau rau hauv thinning, raug siv los yog yooj yim txau. Cov qib steel no yog xeb-resistant, ua prefabricated Cheebtsam tiv thaiv corrosion, ncua lawv lifespan, thinning, txuag zog, thiab txuag lub sij hawm, ib puag ncig, thiab lub zog, pab manufacturers thiab cov neeg siv ntawm prefabricated Cheebtsam. Huab cua-resistant boards yog siv rau zus tau tej cov thawv shipping, railway tsheb, crude roj gantry cranes, chaw nres nkoj tsim, roj ntau lawm cog kev pab cuam platforms thiab cov hlab ntsha uas muaj hydrogen chloride corrosive tshuaj nyob rau hauv chemical cog petroleum khoom.

Cov pa roj carbon sib npaug ntawm cov huab cua-resistant phaj yog siab dua. Qhov siab dua cov pa roj carbon sib npaug ntawm cov phaj hlau stainless, qhov ntau dua qhov kev sib tw hardening, qhov ntau dua qhov txias cracking nyiam nyob rau hauv qhov vuam kub txaus ntshai tsam, thiab qhov phem qhov weldability ntawm stainless hlau phaj. Muaj peb yam tseem ceeb uas ua rau vuam txias tawg: 1. Lub hardening nyiam ntawm cov hlau; 2. Lub vuam tensile kev nyuaj siab; 3. Tus nqi thiab kev faib tawm ntawm peroxide nyob rau hauv welded sib koom.

Qhov qis tshaj ambient kub tso cai thaum lub sij hawm vuam ntawm huab cua-resistant boards yog raws li nram no:
1. Alloy steel thiab dav dav hlau alloy steel (Class A-Ⅰ): -10 degree
2. Alloy steel thiab dav dav hlau alloy steel, tshav kub-lub zog steel thiab alloy cuab yeej steel (Class A-Ⅱ, Ⅲ, B-Ⅰ): 0 degree
3. Thaum tshav kub kub-lub zog steel thiab alloy cuab yeej steel (Class B-II, III): 5 degree

Thaum ib qho ntawm cov xwm txheej hauv qab no tshwm sim hauv qhov chaw vuam, kev tiv thaiv yuav tsum tau ua, txwv tsis pub vuam yog nruj me ntsis txwv:
1. Cua ceev theem ntawm phau ntawv arc vuam tshaj 8 meters / s. Cua ceev theem ntawm phau ntawv arc vuam tshaj 1m / s;
2. Cua av noo tshaj 90%;
3. Cov khoom siv welded yog txaws nrog dej, raug los nag lossis raug pos huab;
4. Thaum qhov kub ntawm qhov welded yog tsawg dua 0 degree .

Cov huab cua-resistant phaj vuam qhov chaw yuav tsum muaj cua tsis kam, tsis muaj dej nag, tiv thaiv khov thiab lwm yam kev ntsuas. Siv alkaline tsawg hydrogen hom vuam hlau thiab flux. Alkaline low-hydrogen vuam hlau thiab flux welded pob qij txha muaj cov ntsiab lus tsis tshua muaj peroxide, zoo flue roj desulfurization, zoo dephosphorization zog, thiab siab tawg toughness. Nws yuav tsum tau cua qhuav ntawm 350 ~ C ~ 420 ~ C rau 1-2 teev ua ntej siv. Lub hom phiaj yog kom tshem tawm cov dej noo hauv nws kom zoo, yog li txo cov pa oxygen ntawm cov welded sib koom ua ke thiab txo qhov nyiam ntawm qhov sib koom ua ke. Vuam accessories yuav tsum raug kuaj thiab ua tau raws li cov qauv ua ntej lawv tuaj yeem sib sau ua ke. Lawv tsis tuaj yeem sib sau ua ke nrog ntau lub zog kom tsis txhob muaj kev sib dhos ntau dhau. Ua tib zoo ntxuav qhov chaw uas yuav tsum tau welded steel phaj thiab thaj tsam li ntawm 20 hli ntawm txhua sab kom tshem tawm cov dej noo, xeb, roj stains thiab lwm yam av. Npaj cov welding sequence scientifically. Tus txheej txheem yog ua kom cov welds feem ntau yuav tsum tau welded nyob rau hauv ib tug tsawg dabtsi yog khoov nruj tus qauv kom ntau li ntau tau kom txo tau cov vuam kev nyuaj siab.
