Ntawm lub plawv ntawm cov txheej txheem no yog ib qho tseem ceeb: Submerged Arc Vuam Hlau. Tab sis dab tsi raws nraim yog submerged arc vuam hlau, thiab vim li cas nws tsis tseem ceeb pom? Qhov xov xwm no 稿 tsoo nws lub luag haujlwm, hom, thiab qhov tseem ceeb hauv kev tsim khoom niaj hnub no.
Txhais tau submerged arc vuam hlau
Submerged arc vuam hlau yog ib qho kev siv hluav taws xob tsim tshwj xeeb rau kev siv hauv submerged arc vuam. Tsis zoo li cov hluav taws xob nthuav tawm hauv cov txheej txheem zoo li MIG los yog Tig vuam, pom hlau ua haujlwm ua ke nrog cov ntsej muag glux. Thaum lub sij hawm vuam, cov hlau yog pub tsis tu ncua rau hauv weld cheeb tsam, uas nws melts los ua tus weld hlau. Ib txhij, flux {{3} txoj hauj lwm dhau ntawm cov xaim pob zeb thiab cov roj av hlau, cais cov hnoos qeev ntawm cov paug ntawm cov pa taws thiab nitrogen.
Qhov kev sib koom ua ke no ntawm xaim thiab flux yog qhov tseem ceeb yog qhov tseem ceeb muab cov khoom uas muab cov khoom siv rau koom nrog cov hlau hauv paus, thaum lub flux ua kom huv, muaj zog weld. Cov hlau txoj kev muaj pes tsawg leeg ua tib zoo engineered kom phim cov hlau hauv paus (piv txwv li cov roj ntsha, ua kom muaj zog) thiab cov khoom siv zoo nkauj, ua kom zoo nkauj hauv cov khoom siv WELD kawg.
Hom Submerged Arc Vuam Hlau thiab lawv Cov Lus Sib Tw
Submerged Arc Vuam cov xov hlau tau faib feem ntau los ntawm lawv cov ntsiab lus alloy, uas dictates lawv cov kev haum rau cov khoom siv hlau thiab cov ntawv thov:
- Cov xov hlau hlau
Hom hom, cov xov hlau cov hlau siv tau siv rau kev siv cov ntaub ntawv me thiab nruab nrab}}} Lawv muaj pes tsawg leeg feem ntau suav nrog 0.05-0.25% carbon, nrog rau cov roj carbon ntau me me (0.3-1.6%) txhawm rau txhim kho lub zog thiab deoxidation. Piv txwv suav nrog AWS AWS A5.17 chav kawm F6A (hlau me) thiab F7A (siab dua manganese kom muaj zog zoo dua).
- Tsawg -} cov xov hlau alloy
Rau vuam qes -} Cov hlau ua kom zoo nkauj (siv cov xov hlau Almoy. Cov alloys txhim kho weld lub zog, kev nruj me ntsis, thiab tiv taus corrosion lossis kub. Piv txwv li, xaim nrog 1-2% chromium thiab 0.5% molybdenum (cr - mo) yog qhov zoo rau high- Cov ntawv thov kub nyiam boiles hlab.
- Stainless Hlau Hlau
Stainless hlau submerged Arc cov xov hlau tsis kam thiab cov khoom siv tshuab ua haujlwm ntawm stainless hlau lub hauv paus hlau (piv txwv li 304, 316, los yog Duplex Stainless hlau). Lawv muaj chromium (18-25%), npib tsib xee (8-20%), thiab feem ntau molybdenum (rau kev txhim kho pittings). Cov hlau no tau siv rau hauv cov khoom siv ua cov khoom siv chinese, cov zaub mov- Cov ntawv thov qib machinery, thiab cov ntawv thov marrine uas yog qhov tseem ceeb.
- Cov xov hlau tshwj xeeb
Rau cov ntawv thov qub, cov xov hlau tshwj xeeb yog muaj, xws li cov neeg siv cov khoom siv high Cov hlau no tau ua rau muaj kev txhim kho kom tau raws li kev ua tau zoo heev, xws li kev tiv thaiv siab dua rau cov hluav taws xob siab lossis muaj kev hnav.
Cov yam ntxwv tseem ceeb ntawm submerged arc vuam hlau
Cov kev ua tau zoo ntawm submerged Arc Vuam hlau yog txhais los ntawm ntau qhov tseem ceeb, txhua yam uas cuam tshuam weld zoo:
Kev sib xws: Cov xov hlau tsim nrog cov hlua hla nruj (feem ntau ± 0.02mm) kom ntseeg tau cov khoom noj kom paub meej txog cov tshuab pom. Cov ciaj uas cov taub sib cuam tshuam tsis zoo melting lossis arc qhov tsis muaj peev xwm, uas tuaj yeem ua rau porosity lossis tsis sib haum xeeb los yog kev tsim cov nyom.
Kev nyiam huv: Kev siab siab - cov hlau zoo yog pub dawb paug ntawm cov roj, xeb, lossis nplai. Txawm tias cov pa hluav taws me me tuaj yeem qhia cov pa roj hauv cov pas dej molten, ua rau cov hws lossis cov kab nrib pleb hauv weld.
Deagidation cov khoom: Ntau cov xov hlau suav nrog cov dej dai, piv txwv li, los yog txhuas los ntawm cov roj ntsha, txo qhov kev pheej hmoo ntawm cov roj oxide, txo qhov kev pheej hmoo ntawm cov pa oxide, txo qhov kev pheej hmoo ntawm cov pa roj av, txo qhov kev pheej hmoo ntawm cov pa oxide, txo qhov kev pheej hmoo ntawm cov pa roj av, txo qhov kev pheej hmoo ntawm cov pa oxide, txo qhov kev pheej hmoo ntawm cov pa oxide, txo qhov kev pheej hmoo ntawm cov pa roj oxes.
Compatibility nrog flux: xaim thiab flux yuav tsum yog cov tshuaj sib phim. Piv txwv li, xaim nrog cov girte girte khub zoo tshaj plaws nrog flux uas tshuav sib npaug cov ntsiab lus silicon kom tsis txhob muaj qhov hnyav dhau ntawm Weld. Mismatched xaim thiab flux yuav ua rau nkig belds lossis fusion fusion.
