Vuam hauv hom tsis siv neeg lossis semi-automatic feem ntau siv qhov chaw siv cov khoom siv xws li flux-cored hlau. Ib qho ntawm nws cov txiaj ntsig tseem ceeb yog lub peev xwm txuag roj, uas yuav siv los tiv thaiv oxidation.

Wire description

Kev siv ntau tshaj plaws ntawm cov xaim hluav taws xob yog thaum nws tsim nyog ua haujlwm nrog cov hlau xws li tooj liab, titanium thiab txhuas. Lwm qhov tshwj xeeb cuam tshuam qhov vuam seam. Nws puv tawm heev du thiab heev check. Feem ntau, lub ntsiab tivthaiv yog granular flux. Txawm hais tias qhov no tsis yog ib txwm muaj, muaj cov xwm txheej thaum oxide, ntsev cov khoom siv. Tsis tas li ntawd, qee zaum, ib qho kev sib xyaw ua ke ntawm ntsev oxide puag yog siv.

Key Benefits

Nws tsim nyog pib nrog qhov tseeb tias cov xaim flux-cored muaj qib siab ntawm melting. Qhov no tso cai rau nws siv rau kev ua haujlwm nrog cov ntaub ntawv refractory. Tsis tas li ntawd, thaum lub sij hawm ua hauj lwm, lub siab vuam ceev yog guaranteed,thiab kev ua hauj lwm arc yog yam ntxwv ntawm stability thiab softness. Lub arc kuj kub nyhiab tusyees, uas yog vim li cas lub seam hloov mus ua tus txawm. Ib qho ntawm qhov zoo tshaj plaws yog tias tom qab vuam nrog cov xaim flux-cored, nws txaus los tshem tawm cov slag txheej los ntawm vuam.

Ntxiv rau qhov zoo tshaj plaws saum toj no, muaj ntau yam ntxiv:

• zoo vuam cheeb tsam tiv thaiv;
• kev ua haujlwm siab ceev yog nrog rau kev ua haujlwm;
• melting tuaj yeem nqa mus rau qhov tob loj txaus, thiab tsis muaj qhov tawg thaum ua haujlwm;
• thaum lub sijhawm ua haujlwm tsis muaj cov tshuaj tsis haum tshuaj raug tso tawm;
• koj tuaj yeem tswj cov pa oxygen uas muaj nyob hauv qhov vuam;
• Kev siv cov flux-cored hlau vuam tshuab pab txhim kho cov qauv vuam zoo.

Nws yog ib qho tsim nyog sau cia tias qhov kev tiv thaiv ntawm qhov chaw vuam yog ua tau raws li qhov tseeb tias cov hlau muaj flux. Vim li no, atmospheric gases tsis ncav cuag qhov chaw vuam, thiab yog li ntawd tsis oxidize cov khoom welded. Nws yog ib nqi sau cia hais tias vim muaj xws li ib tug xov tooj ntawm zoo, lub flux hlau rau semi-automatic yog siv tsis tau tsuas yog los ntawm amateurs rau vuam, tab sis kuj los ntawm cov tub txawg.

Main Applications

Feem ntau, lub tshuab vuam uas ua haujlwm siv cov hlau no yog siv los koom nrog cov ntaub ntawv xws li cov hlau tsis muaj hlau, hlau alloy thiab lwm yam khoom siv high-alloy.

Nyob ntawm seb puas yogdab tsi raws nraim yog yuav tsum tau welded, muaj pes tsawg leeg ntawm flux yuav hloov. Piv txwv li, yog tias nws yog ib qho tsim nyog los txuas ua ke cov khoom uas yog cov pab pawg ntawm cov hlau tsis tshua muaj hlau, ces oxide flux yuav tsum tau siv. Yog tias koj yuav tsum ua haujlwm nrog cov hlau uas tsis yog-ferrous, ces cov flux-cored vuam hlau yuav tsum muaj cov ntsev ntsev. Rau cov hlau alloyed, kev sib xyaw ua ke ntawm oxide thiab ntsev yog siv.

Dhau li ntawm, lwm qhov tseem ceeb ntawm cov xaim, txoj kab uas hla, kuj tseem yuav hloov. Qhov ntsuas no hloov pauv hauv qhov dav dav, los ntawm 0.6 hli mus rau 8 hli. Ntawm chav kawm, qhov tuab ntawm cov vuam hlau, ntev nws yuav siv sij hawm rau nws kom yaj. Thiab qhov no yuav nyob ntawm tus nqi pub. Vim yog cov xwm txheej no, nws hloov tawm tias yog tias cov thickness ntawm cov khoom yog tsawg los yog nws muaj pes tsawg leeg yog yooj yim rau welding, ces siv ib tug tuab hlau yog yooj yim unprofitable.

Xaiv hlau los ntawm kab

Raws li tau piav qhia saum toj no, thaum welding nrog flux-cored hlau, ib qho khoom siv nrog lub cheeb ntawm 0.6 txog 8 hli. Ntxiv nrog rau tus nqi pub, qhov ceev ntawm nws melting kuj nyob ntawm qhov ntsuas no. Ob peb yam no tseem ceeb heev thiab yuav tsum tau coj mus rau hauv tus account thaum xaiv.

Cia peb hais tias kom tau txais qhov siab tshaj plaws txawm tias seam, nws yog qhov tsim nyog kom cov hlau ntev. Piv txwv li, yog tias nws yuav tsum tau welding ib tug txaus refractory khoom ua ke, thiab lub seam yuav tsum muaj zog thiab tuab, ces lub thickness ntawm electrode yuav tsum tau loj. Yog hais tias nws yog tsim nyog los ua hauj lwm nrog txaus moshlau nyob rau hauv cov nqe lus ntawm vuam, tsis tas yuav siv cov hlau tuab.

Yog tias txoj kab uas hla tau raug xaiv kom raug thiab tag nrho cov kev cai rau kev ua haujlwm tau raug soj ntsuam, tom qab ntawd vuam nrog cov xaim flux-cored tsis muaj roj tuaj yeem muab cov vuam zoo, cov npoo siab ntawm kev nyab xeeb thiab tsim kev sib txuas uas yuav yog resistant rau atmospheric influences. Peb yam no ua rau nws muaj peev xwm siv cov qauv kev sib txuas hauv txoj kev no txawm tias nyob rau hauv qhov chaw uas muaj huab cua phem, piv txwv li, nyob rau hauv ib cheeb tsam uas muaj zog ntxiv.
