Kev sib koom qhuav ntawm cov pa sib tov kev xaiv thaum vuam

Hauv kev ua haujlwm vuam ua haujlwm, xaiv cov roj muaj kuab haum yog tus yuam sij rau kom ua kom zoo thiab ua tau zoo. Nov yog qee cov lus qhia ntawm kev xaiv cov roj ntsha kom pab koj ua kom muaj kev txiav txim siab ncaj qha thiab muaj tseeb.

Lub luag haujlwm ntawm cov roj av vuam

AR: feem ntau siv nyob rau hauv tig vuam thiab mig vuam vim tias nws tuaj yeem muab lub arc ruaj khov thiab ntxuav Weld Seam.

O ₂: Ntxiv ib qho me me ntawm o ₂ Thaum qee lub sijhawm vuam vuam tuaj yeem nce qhov kub thiab lub raj dej ntawm Molten.

CO ₂: Thaum sib xyaw nrog AR, nws yog feem ntau siv nyob rau hauv mig vuam los txhim kho vuam kev vuam thiab nkag mus tob.

Nws: Txawm hais tias tus nqi yog siab, nws tuaj yeem nce ARC Kub thiab vuam nrawm, tshwj xeeb yog tsim nyog rau cov ntaub ntawv siv vuam xws li aluminium alloys.

Cov roj sib xyaw yog feem ntau muab faib ua ob pawg: binary sib xyaw thiab cov ternary sib tov.

Binary Sib xyaw Roj

Binary roj sib xyaw yog cov roj system muaj ntau ntawm ob lub roj xyaw sib xyaw ua ke. Hauv vuam, muaj cov binary sib xyaw ua ke suav nrog cov hauv qab no:

1. AR + O: Ntxiv tus nqi tsim nyog ntawm O ₂ los AR yuav ua kom zoo ua rau muaj kev ruaj khov arc thiab kho kom huv. Cov yam ntxwv combusion ntawm O ₂ tuaj yeem nce qhov kub ntawm cov hlau nyob hauv cov pas dej mold, txhawb kev vuam hlau, kom nrawm vuam ceev, thiab txhim kho vuam ua kom zoo. Cov roj sib xyaw no haum rau vuam cov hlau, cov hlau nplaum tsawg-hlau, thiab hlau hlau tuab.

2. Ar + co ₂: Co. muaj kev txhim kho vuam lub zog thiab corrosion tsis kam, tab sis cov roj ntshiab pab txhawb ntau dhau. Nws sib xyaw ua ke ruaj khov hauv nws tuaj yeem txo cov hlau sib tsoo tus nqi. Cov roj sib xyaw no tseem haum rau vuam cov hlau thiab hlau stainless.

3. AR + H ₂: h ₂ yog kev txo cov roj uas tsis muaj pa, tiv thaiv kom muaj qhov muag ntawm cov co, thiab tiv thaiv kev siv vuam tsis xws luag. Cov tshuaj sib xyaw no muaj cov kev siv vuam zoo ntawm cov neeg npib tsib xee raws li cov neeg tooj liab, Nickel.

Ternary sib xyaw

Lub sib xyaw ua ke yog cov roj system muaj kev sib xyaw ntawm peb cov roj xyaw sib xyaw ua feem. Hauv vuam, cov ternary sib xyaw suav nrog cov hauv qab no:

1. AR + O ₂ + CO + CO + COLLE: Cov kev sib xyaw ternary sib xyaw ua ke ntawm Ar + O ₂ binary sib xyaw, txo cov bubt nix, thiab txhim kho weld zoo. Nws tuaj yeem siv rau vuam carbon hlau, cov hlau me me, thiab hlau hlau ntawm cov hlau sib txawv, nrog ntau cov ntawv thov.

2. Ar + nws + Co: Cov roj sib xyaw no tuaj yeem txhim kho Arc ruaj khov thiab ua kom muaj qhov kub thiab txias, thiab txhim kho vuam zoo thiab nrawm. Vim tias nws tau ua cov roj inert nrog cov tshuaj tsis muaj tshuaj, nws cov kev cuam tshuam oxidation ntawm Weld Seam yog tsawg. Cov roj sib xyaw no feem ntau siv nyob rau ntau hom kev luv luv circuit arc vuam thiab dhau vuam.

Them sai sai rau kev faib ua feem ntawm cov pa roj sib xyaw

Qhov kev faib ua feem ntawm cov roj sib xyaw nrog cov txiaj ntsig vuam. Piv txwv li, nyob rau hauv kev sib xyaw ntawm ar thiab cov roj av, nce ntxiv rau kev sib tw vuam thiab qhov tob tob, tab sis kuj yuav nce qhov kev pheej hmoo ntawm kev sib cais thiab ua kom muaj kev pheej hmoo. Yog li ntawd, nws yog qhov yuav tsum tau kho cov feem ntawm cov roj sib xyaw raws li cov kev xav tau.

Thaum xaiv cov roj sib xyaw, yam xws li cov hom thiab cov yam ntxwv ntawm cov ntaub ntawv vuam, cov hau kev vuam yuav tsum tau txiav txim siab. Cov roj sib txawv nyias muaj cov yam ntxwv sib txawv thiab siv tau ntau ntau, thiab yuav tsum tau xaiv raws li cov xwm txheej tshwj xeeb.
