E312-16 ELCETODE

 

Nyob rau hauv lub tshav pob ntawm stainless hlau vuam, ib lub vuam hluav taws xob uas sib xyaw ua ke, thiab kev siv dav dav yog feem ntau yog tus yuam sij los txhim kho vuam zoo thiab ua haujlwm tau zoo. Lub AWS E312 {{- 16 stainless hlau vuam ua los ntawm dej hiav txwv vuam muag los ntawm cov khoom siv vuam loj, thiab cov kev ua tau zoo tshaj plaws, thiab hloov kho cov xwm txheej zoo dua qub. Txhua qhov ntsuas tau ua raws cov qauv thoob ntiaj teb thiab tau dhau ntau cov ntawv pov thawj kev lees paub, muab cov khoom lag luam muaj txiaj ntsig rau Vuam.

I. Cov khoom lag luam tseem ceeb: kho kom meej ntawm kev ua haujlwm yooj yim

AWS E312-16 yog hom Duplex Stainless Hlau Vuam Electrode. Nws cov qauv tseem ceeb yog ua tib zoo tsim los xyuas kom ntseeg tau tias muaj peev xwm ruaj khov thiab kev ntseeg tau hauv ntau cov xwm txheej vuam. Cov kev txwv tshwj xeeb yog raws li hauv qab no:

1. Cov ntsiab lus yooj yim

Khoom: Ntshiab stainless hlau cov khoom siv, kom cov khoom lag luam tsis kam thiab lub zog ntawm welded sib koom ua ke;

Qauv Qauv: Ua raws li cov qauv thoob ntiaj teb AWS A5.4 thiab sib raug rau tus qauv hauv tebchaws GB E312-16, muaj kev sib raug zoo;

Qhov loj me specifications: Muaj nyob rau hauv plaub feem ntau siv diameters: 2.0mm, 2.5mm, 3.2 hli, thiab 4.0mm. Qhov ntev yog uniformly 300mm-500mm, adapting rau kev siv vuam xav tau ntawm cov haujlwm tuab nrog cov thickness.

Cov ntawv pov thawj zoo: Tau dhau ISO 9001-2008 Kev tswj hwm kev tswj hwm cov qauv zoo, CE kev ua yeeb yam nyab xeeb, thiab SGS kuaj. OEM kev customization tseem muaj kev txhawb nqa kom tau raws li cov kev xav tau tus kheej.

2. Cov khoom ntawm cov hlau tso khoom: zoo heev ob qho tib si hauv kev tawg tsis kam thiab lub zog

Cov muaj pes tsawg leeg thiab cov khoom siv tshuab ntawm cov hlau tso tawm ncaj qha txiav txim siab qhov zoo ntawm welded sib koom tes. AWS E312-16 ua yeeb yam zoo nyob hauv qhov no:

 

• Tshuaj lom neeg cov tshuaj xyaw (feem ntau feem): Cov ntsiab lus carbon tsawg dua los yog sib npaug ntawm 0.15% (recompitalively 0.5% (txhim kho kev pheej hmoo ntawm cov kab nrib pleb ipirity cov ntsiab lus), thiab ob qho tib si Molybdenum thiab tooj tsawg dua lossis sib npaug rau 0.75%, ua rau muaj kev sib tw sib npaug;
• Cov Khoom Siv Neeg Kho Tshuab: Tensile lub zog loj dua los yog sib npaug rau 660Mpa, elongation ntau dua lossis sib npaug li 22%. Cov hlau tso khoom tso tawm muaj 40% ferrite, uas txhim kho txhim kho kev tawg ua thiab txo cov kev nyuaj siab vuam txawm nyob hauv cov nyom muaj kev nyuaj siab.

 

Ii. Kev Qhia Hauv Vuam: Kev Siv Kev Tshawb Fawb los xyuas kom ntseeg tau

Txhawm rau muab cov kev ua si tag nrho rau cov txiaj ntsig zoo ntawm AWS E312 {}} 16, nws yog ib qho tsim nyog los tswj cov txheej txheem ua ntej los ntawm kev hloov chaw tam sim no:

1. Ua ntej -} vuam npaj

Fai fab: Cov electrodes yuav tsum ci ntawm 250℃rau 1 teev ua ntej siv kom tshem tawm noo noo los ntawm cov hluav taws xob txheej thiab zam kev ua yeeb yam thaum vuam;

Kev xaiv tam sim no: Nws raug nquahu kom siv ncaj qha tam sim no (DC +) rau vuam. Qhov kev siv hluav taws xob tam sim no yuav tsum tau hloov kho raws li cov hluav taws xob lub taub kom tiv thaiv cov xaim hluav taws xob los yog overheating ntawm cov pas dej molten vim muaj ntau tam sim no:

• Inch 2.5mm: 50-80a;
• Inch 3.2mm: 80-110a;
• Inch 4.0mm: 110-160A;
• Txoj kab uas hla 5.0m: 160-220a (hloov tshiab (AC) Vuam yog txaus siab).

2. Vuam Txoj Haujlwm

Cov chaw hluav taws xob no tsim nyog rau ntau txoj kev vuam, suav nrog cov vuam muag (HF), cov vuam vuam (f) {{} down {down vuam (VU). Nws ua tau raws li kev xav tau vuam xav tau ntawm cov kav dej xav tau ntawm pipelines, ntim, cov qauv, thiab lwm yam sib txawv.

 

III. Daim Ntawv Thov Zaj Dab Tsi: Npog High-}} Thov kev xav tau vuam

Nrog nws cov kev tawg zoo tsis kam thiab sib xyaw, AWS E312-16 muaj ntau yam kev thov rau cov khoom siv rau lub zog thiab corrosion tsis zoo ntawm welded pob qijtrial:

 

• Vuam ntawm high -} cov hlau carbon thiab tuam hlau: daws qhov teeb meem ntawm kev tawg yooj yim thaum lub vuam ntawm cov hlau no;
• Vuam ntawm high - cov hlau thiab armor steel thiab armor hlau: adapting mus rau huab cua sov heev thiab siab} lub zog ua hauj lwm tej yam kev ua haujlwm;
• Vuam ntawm dissimilility hlau: xws li kev sib txuas ntawm stainless hlau thiab carbon hlau lossis qis}} alllotic steel, kom muaj kev sib xyaw ntawm cov sib koom ua ke;
• Vuam ntawm cov hlau tshwj xeeb: suav nrog CR29NI9 cam khwb cia hlau, thiab ntau "cov teeb meem sib tw ntawm cov pa hluav taws xob.

 

IV. Cov Khoom Muag Khoom Zoo thiab Cov Kev Pab: Ntsuas Ntsuas thiab Kev Tawm Tsam Kev Yooj Yim

Ntxiv rau kev ua tau zoo, AWS E312-16 tseem muaj kev sib tw muaj zog ntawm cov neeg siv cov kev pabcuam thiab cov kev pabcuam tshaj lij:

 

• Tus txheej txheem zoo: Tsis muaj lub tog raj thaum vuam, thiab muaj kev sib xyaw zoo nkauj rau kev ua tiav ntxiv (yooj yim rau kev txiav thiab zom);
• Kev Ntim Ntim: Tus qauv ntim yog 5kg / pvc box (nrog ntsws zaj duab xis), 4 thawv (20kg) ib lub thawv, thiab 50 poom (1 tuj) ib pallet. Customized ntim kuj tseem tuaj yeem muab raws li cov neeg siv khoom xav tau;
• Kev xa khoom thiab cov kev pabcuam: Hauv {- Cov khoom lag luam tuaj yeem xa tuaj ua ntej 8-25 hnub, thiab cov khoom lag luam raug xa tawm hauv 25 hnub tom qab kev txiav txim kev pom zoo. Ntau cov ntsiab lus ua haujlwm xws li Cif, CFR, FOB, thiab Exw tau txais kev txhawb nqa, thiab cov qauv pub dawb tau muab rau kev sib tw kom txo qis kev pheej hmoo.
