Feem ntau, cov hluav taws xob cua sov feem ntau muab los ntawm cov tuam ntxhab yog cov khoom siv hluav taws xob cua sov yooj yim lossis cov khoom siv raw, yog li yuav tsum ua tiav ntxiv tom qab tus neeg siv yuav lawv ua ntej lawv tuaj yeem siv tau. Vuam cov cua sov ua kom sov yog ib qho ntawm cov txheej txheem ua tau zoo heev, uas muaj txiaj ntsig zoo rau cov neeg siv los teeb tsa thiab debug raws li lawv qhov kev siv tiag.
1. Vuam kev ua tau zoo ntawm cov cua sov ua kom sov (npib tsib xee-chromium, hlau-chromium-aluminium):
1. Vuam kev ua tau zoo ntawm nickel-chromium thiab nickel-chromium-iron series:
Nickel-chromium thiab npib tsib xee-chromium-hlau series muaj qhov ua tau zoo vuam, cov yas hloov pauv tom qab vuam me me, yuav tsis muaj kev tawg thaum teeb tsa, thiab tsis muaj qhov tawg yuav tshwm sim tom qab siv ntev, thiab cov khoom puas tuaj yeem kho tau .
2. Vuam kev ua tau zoo ntawm FeCrAl series:
Cov hlau-chromium-aluminium series muaj kev ua haujlwm tsis zoo, cov yas txo qis tom qab vuam, lub zog nce ntxiv, thiab qhov tshwm sim embrittlement tshwm sim. Thaum txhim kho, xyuam xim rau qhov tshwm sim ntawm kev tawg, thiab cov hlau tsis tuaj yeem txuas thiab kho tau.
Yuav ua li cas txhawm rau txhim kho kev ua haujlwm vuam ntawm FeCrAl series:
1) Siv cov hluav taws xob tshwj xeeb uas muaj cov hlau tsis tshua muaj hlau oxide los txo cov yas poob qis.
2) Siv kev tiv thaiv huab cua vuam, xws li argon arc vuam, txhawm rau tiv thaiv aluminium oxidation.
3) Txais yuav tshwj xeeb txoj hauv kev txuas rau vuam.
4) Qhov chaw vuam nrawm yog siv rau vuam kom luv lub sijhawm kub nyob.
5) Ua kom txias sai sai tom qab vuam.
2. Vuam txoj kev ntawm cov cua sov ua kom sov (npib tsib xee-chromium, hlau-chromium-txhuas):
1. Nickel-chromium thiab nickel-chromium-iron series:
Feem ntau, siv arc vuam siv, thiab siv cov hlau sib txuas zoo ib yam, thiab argon tungsten arc vuam yuav tsum siv thaum qhov xav tau zoo.
2. Fe-Cr-Al series:
Feem ntau, siv vuam vuam siv, tab sis ntshav arc vuam, siv hluav taws xob nqaj vuam, tiv thaiv vuam thiab lwm yam kev siv vuam tsim rau hlau-chromium-aluminium alloys kuj tseem tuaj yeem siv tau. Cov txheej txheem vuam no yuav tsum muaj cov yam ntxwv ntawm kev tiv thaiv roj, ntsuas kub, ua kom nrawm nrawm, thiab tsis muaj cua sov cuam tshuam.
