Yuav ua li cas yog cov qauv ntawm flux-cored vuam hlau cais?
1.Kev faib tawm los ntawm lub hom phiaj
①.Cov yam ntxwv steel flux-cored vuam hlau:
Feem ntau yog siv rau vuam yam ntxwv xws li carbon steel thiab tsawg alloy steel. Tus qauv feem ntau pib nrog tsab ntawv "E", ua raws li kev sib xyaw ntawm cov lej thiab cov ntawv. Piv txwv li, E501T-1, "E" sawv cev rau cov electrode (tseem siv ntawm no los txheeb xyuas cov flux-cored vuam hlau), "50" sawv cev rau qhov tsawg kawg nkaus tensile lub zog ntawm cov hlau deposited yog li 500MPa, "1" sawv cev welding txoj hauj lwm yog tag nrho-txoj hauj lwm vuam, "T" sawv cev rau cov flux-cored vuam hlau, thiab "-1" yog cov kev faib code ntawm lub flux-cored vuam hlau. Cov kev faib cov lej sib txawv sawv cev sib txawv flux core compositions, vuam yam ntxwv, thiab lwm yam.
②Stainless hlau flux-cored vuam hlau:
Siv rau vuam ntau yam ntaub ntawv stainless hlau. Cov qauv xws li E308LT1-1, qhov "E308L" txhais tau hais tias cov vuam hlau yog siv los vuam 308L stainless hlau, thiab lub ntsiab lus ntawm "T1-1" zoo ib yam li cov qauv hlau flux-cored vuam hlau, uas kuj qhia cov ntaub ntawv xws li vuam txoj hauj lwm thiab flux-cored vuam hlau hom. Hom kev txheeb xyuas tus qauv no tuaj yeem pab cov neeg siv nkag siab sai sai rau qhov siv tau ntawm cov vuam hlau.
③Wear-resistant cladding flux-cored vuam hlau:
Nws yog tsuas yog siv rau cladding hnav-resistant khaubncaws sab nraud povtseg ntawm hlau nto. Cov qauv yuav muaj kev cuam tshuam cov ntaub ntawv hais txog cov yam ntxwv ntawm hnav-resistant, xws li hardness ntau yam, thiab lwm yam. Piv txwv li, ib co qauv ntawm hnav-resistant cladding flux-cored vuam hlau yog cim nrog lub Rockwell hardness (HRC) tus nqi ntau ntawm cov txheej cladding, uas yog qhov yooj yim rau cov neeg siv xaiv qhov tsim nyog vuam hlau raws li qhov yuav tsum tau hnav tsis kam.
2.Classification los ntawm shielding gas hom
①Cov pa roj carbon dioxide (CO₂) shielded flux-cored vuam hlau:
Qhov no yog hom tshaj plaws. Nws cov qauv yuav tsis feem ntau hais txog cov roj thaiv kev tiv thaiv hauv kev txheeb xyuas, vim tias CO₂ shielded flux-cored vuam hlau yog dav siv. Txawm li cas los xij, cov ncauj lus kom ntxaws xws li cov khoom siv phau ntawv yuav qhia tias nws tsim nyog rau CO₂ gas shielded vuam. Piv txwv li, E501T-1 tau hais los saum toj no tuaj yeem siv rau CO₂ gas shielded vuam. Nws tuaj yeem ua kom muaj kev sib txuas zoo hauv CO₂ ib puag ncig, xws li arc ruaj khov thiab qhov tsim nyog ceev ceev.
②Argon (Ar) shielded los yog sib xyaw roj shielded flux-cored vuam hlau:
Nws yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau muaj dua vuam zoo yuav tsum tau thiab ib tug ruaj khov shielding roj ib puag ncig yuav tsum tau. Tus qauv yuav qhia tau hais tias nws haum rau argon lossis argon-carbon dioxide sib xyaw roj tiv thaiv. Hom vuam hlau no yog siv dav hauv cov khoom siv vuam xws li stainless hlau, vim tias kev tiv thaiv argon tuaj yeem txo cov oxidation thiab nitridation ntawm cov vuam thiab tau txais cov vuam zoo dua.
③Self-shielded flux-cored vuam hlau:
Tus qauv yuav qhia txog "kev tiv thaiv tus kheej" feature. Hom vuam hlau no tsis tas yuav muaj cov roj thaiv thaiv sab nraud thaum vuam, thiab tso siab rau cov roj uas tsim los ntawm qhov decomposition ntawm flux core nws tus kheej los tiv thaiv lub pas dej molten. Piv txwv li, ib co self-shielded flux-cored vuam hlau qauv yuav muaj cov cim tshwj xeeb kom paub qhov txawv ntawm lwm yam vuam hlau uas yuav tsum tau shielding roj, uas yog yooj yim rau siv nyob rau hauv tej qhov chaw sab nraum zoov los yog tsis-gas-shielded.
3.Kev faib tawm los ntawm slag system ntawm flux-cored vuam hlau
①Titanium (acidic) flux-cored vuam hlau:
Tus qauv tuaj yeem cuam tshuam nws hom slag system los ntawm cov cai muaj pes tsawg leeg lossis lwm cov lus qhia. Lub flux core ntawm titanium-hom flux-cored vuam hlau muaj ntau titanium oxide, thiab nws cov txheej txheem vuam yog zoo, lub arc yog ruaj khov, lub spatter me me, thiab cov vuam zoo nkauj. Nws feem ntau yog siv rau vuam nrog cov kev xav tau siab rau cov tsos zoo. Txawm li cas los xij, nws cov vuam hlau toughness thiab tawg tsis kam yog me ntsis phem dua li cov alkaline flux-cored vuam hlau.
②Calcium-type (alkaline) flux-cored vuam hlau:
Lub ntsiab tseem ceeb ntawm cov tub ntxhais flux ntawm hom vuam hlau no yog cov calcium sib txuas. Nws cov yam ntxwv yog qhov zoo toughness thiab tawg tsis kam ntawm vuam hlau, thiab cov welds zoo tuaj yeem tau txais, tab sis cov txheej txheem vuam kev ua tau zoo yog me ntsis phem dua li cov kua qaub flux-cored vuam hlau, xws li me ntsis tsis muaj zog arc stability thiab me ntsis loj spatter. . Kev txheeb xyuas tus qauv tuaj yeem suav nrog cov lej ntsig txog cov yam ntxwv ntawm lub tshuab slag, uas yog siv los paub qhov sib txawv ntawm cov xov hlau ntawm cov tshuab slag sib txawv.
③Lwm yam slag-based flux-cored vuam hlau:
Kuj tseem muaj qee qhov tshwj xeeb slag-raws li flux-cored vuam hlau, xws li txhuas hom, zirconium hom, thiab lwm yam. Lawv txhua tus muaj lawv tus kheej tshwj xeeb vuam kev ua tau zoo thiab daim ntawv thov ntau yam, thiab cov qauv kev faib tawm kuj yuav coj mus rau hauv tus account cov yam ntxwv thiab daim ntawv thov teb. ntawm cov tshuab slag no los pab cov neeg siv xaiv cov vuam hlau uas haum rau lawv cov kev xav tau.
