Thaum nws yog qhov zoo tshaj plaws los hloov koj txoj hauv kev rau cov kev xav tau ntawm koj qhov project, cov lus qhia hauv qab no yuav ua kom muaj kev sib txuas zoo thiab siv tau ntev ntev txawm tias koj siv stainless hlau.
1. NTAUB NTAWV TIV THAIV STAINLESS NTAWM NTAU NTAU UA HAUJ LWM
Cov hlau tsis muaj hlau yuav raug paug los ntawm cov pa roj carbon ntau thiab lwm yam hlau. Thaum qhov no tshwm sim, nws ho txo cov corrosion kuj ntawm stainless.
Kev ntxuav koj lub ntsej muag tsis yog tsuas yog pab txo cov kab mob sib kis tab sis yuav ntxiv dag zog rau cov vuam.
Yog tias koj tab tom ntxuav lub ntsej muag siv cov txhuam hlau, nco ntsoov tias cov txhuam hniav tsuas yog siv rau ntawm cov hlau tsis muaj hlau vim tias cov khoom siv microscopic tshuav ntawm txhuam los ntawm lwm cov hlau tuaj yeem nkag mus rau saum npoo ntawm cov hlau thaum ntxuav ua rau muaj teeb meem tom qab.
Cov kev kho tshwj xeeb pickling thiab tu cov kev kho mob tuaj yeem muab txoj hauv kev tsis muaj txhuam ntawm kev ntxuav stainless uas muaj kev nyab xeeb rau vuam kom txo tau cov kab mob tsis zoo.
2. Xaiv cov khoom siv filler zoo ib yam li cov hlau uas koj tab tom vuam
Xaiv cov khoom siv muab tub lim tsim nyog yog qhov tseem ceeb rau ob qho tib si kom ntseeg tau tias muaj zog vuam thiab tswj xyuas qhov corrosion kuj ntawm koj cov hlau stainless.
Thaum xaiv ib tug muab tub lim, xav txog ob qho tib si qib ntawm steel thiab cov lus txuas nrog.
Piv txwv li, koj yuav tsis xav siv high-carbon stainless hlau, xws li 316H, raws li ib tug muab tub lim thaum welding ib tug tsawg-carbon stainless hlau, xws li 316L.
Txawm hais tias cov lus pom zoo sib txawv raws li cov hlau koj siv, feem ntau koj xav siv cov muab tub lim uas sib tw lossis tshaj cov qib ntawm cov hlau hauv paus kom ntseeg tau tias cov txiaj ntsig zoo.
Rau duplex steels, tej zaum koj yuav tau hloov kho tshuaj rau koj cov hlau muab tub lim -- xws li ntxiv npib tsib xee -- rau account rau qhov sib npaug ntawm austenitic thiab ferritic zog nyob rau hauv qib ntawm duplex stainless koj welding.
3. Siv cov cuab yeej txhim khu kev qha los taug qab cov ntaub ntawv kub
Ua tau zoo, zoo vuam ntawm stainless hlau yog txhua yam hais txog kev tswj qhov kub thiab txias.
Kev saib xyuas qhov kub thiab txias thoob plaws hauv cov txheej txheem vuam yog ib txoj hauv kev yooj yim los xyuas kom meej cov txiaj ntsig tau ntev thiab tsis txhob cuam tshuam qhov zoo ntawm koj cov stainless.
Nrov kub saib xyuas kev xaiv muaj xws li:
Kub taw qhia sticks: Cov sticks no txhim khu kev qha thiab muaj pov thawj rau kev taug qab qhov kub thiab txias thaum koj vuam. Txawm li cas los xij, lawv feem ntau txwv nyob rau hauv qhov ntsuas kub uas lawv tuaj yeem taug qab. Yog tias koj tab tom vuam hla ntau qhov ntau, koj yuav xav tau ntau hom sticks kom raug ntsuas kub.
Electronic infrared (IR) tus pas ntsuas kub: Yog tias koj muaj kab pom ntawm lub hauv paus hlau, IR tus pas ntsuas kub tso cai rau koj saib xyuas qhov kub thiab txias kom raug. Txawm li cas los xij, cov teeb pom kev zoo thiab qhov ua tiav ntawm cov hlau yuav ua rau muaj kev txhawj xeeb txog qhov tseeb.
Kev ntsuas kub ntawm hluav taws xob: Kev sojntsuam yog qhov zoo tagnrho thaum koj tuaj yeem nqa lawv hauv koj qhov chaw vuam. Lawv yuav tsum kov lub npoo ntawm lub hauv paus hlau kom nyeem qhov kub thiab txias, yog li khaws cov kev txwv ntawm qhov chaw ua haujlwm thiab qhov kev txhawj xeeb ntawm qhov chaw nyob hauv siab ua ntej yuav mus.
4. Saib rau WARPING ntawm THINNER STAINLESS PARTS
Overheating stainless tuaj yeem cuam tshuam nws cov corrosion kuj thiab lub zog. Txawm li cas los xij, thaum ua hauj lwm nrog nyias stainless hlau qhov chaw lossis cov nplooj ntawv, muaj kev pheej hmoo ntxiv rau qhov kub siab -- warping.
Txhawm rau pab txo qis kev pheej hmoo ntawm kev sib tsoo, pib nrog lub sijhawm qis thiab siv cov tack welds kom ruaj ntseg ua ntej sau cov vuam tom qab.
Yog tias koj tsis tuaj yeem siv tack welds los tso cov hlau hauv lub hauv paus, welding luv luv ntawm 3 mus rau 5 vib nas this tuaj yeem pab kom tsis txhob muaj cua sov thaum tso cai rau koj kom raug thiab nrawm nrawm.
5. Ib txwm xav txog CORROSION RESISTANCE ntawm vuam
Yog tias koj tsis siv cov tshuaj tiv thaiv corrosion, nco ntsoov kho qhov chaw vuam kom tsis txhob xeb.
primer, ntshiab xim, los yog pickling thiab passivation kev kho mob yuav pab tau txhim kho corrosion kuj thiab xyuas kom meej tias koj welds yog check thiab kav ntev li cov stainless puag ncig lawv.
