Lub tshuab hluav taws xob cua sov tube tsim tau qhia txog lub hauv paus ntsiab lus ntawm cov cua kub cua sov ntawm hluav taws xob cua sov raj

Lub tshuab hluav taws xob cua sov tube tsim tau qhia txog lub hauv paus ntsiab lus ntawm cov cua kub cua sov ntawm hluav taws xob cua sov raj

Rau cov ntaub ntawv siv rau cov khoom cua sov ncaj qha rhuab los ntawm hluav taws xob cua sov raj, hluav taws xob cua sov raj feem ntau yuav tsum muaj hluav taws xob resistivity, tsis tshua muaj kub coefficient, me me kub deformation, thiab tsawg susceptibility rau embrittlement. Feem ntau siv yog cov ntaub ntawv hlau xws li hlau aluminium alloys thiab nickel chromium alloys, nrog rau cov ntaub ntawv tsis yog xim hlau xws li silicon carbide thiab molybdenum disilicide.

Raws li cov ntaub ntawv, kev ua haujlwm siab dua ntawm cov hlau cua sov tuaj yeem ncav cuag 1000-1500 degree ; Kev ua haujlwm siab dua ntawm cov cua sov uas tsis yog xim hlau tuaj yeem ncav cuag 1500-1700 degree . Cov khoom siv tom kawg yog qhov yooj yim rau kev siv thiab tuaj yeem hloov tau los ntawm lub qhov cub kub, tab sis cov cuab yeej tswj kev siab yuav tsum tau ua thaum ua haujlwm. Nws lifespan yog luv dua li ntawm alloy cua sov ntsiab. Nws feem ntau yog siv rau hauv qhov cub kub kub, hauv zos thiab lub sijhawm tshwj xeeb uas qhov kub siab tshaj cov ntaub ntawv hlau cua sov thiab tso cai rau kev ua haujlwm siab dua.

1. Lub hauv paus ntsiab lus ntawm kev xaiv cov raj xa dej: kub tsis kam thiab corrosion kuj

2. Kev xaiv cov hlau tsis kam.

303 stainless hlau khoom, vim nws cov ntsiab lus sulfur thiab yooj yim ntawm kev txiav, feem ntau yog siv nyob rau hauv lub sij hawm uas txiav yog yooj yim thiab siab smoothness ntawm stainless hlau yuav tsum tau.

Hluav taws xob cua sov tube tuam ntxhab qhia cov lus qhia rau kev xaiv cov ntaub ntawv raw rau hluav taws xob cua sov raj

Qhov zoo ntawm cov ntaub ntawv yog ib qho tseem ceeb heev cuam tshuam rau qhov zoo ntawm stainless hlau hluav taws xob cua sov raj. Tsim nyog xaiv cov ntaub ntawv raw rau hluav taws xob cua sov raj yog qhov yuav tsum tau ua ua ntej kom ntseeg tau qhov zoo ntawm hluav taws xob cua sov raj. Kev xaiv cov ntaub ntawv suav nrog cov ntsiab lus hauv qab no:

Piv nrog 304 stainless hlau, 304L stainless hlau muaj cov ntsiab lus qis dua. Thaum vuam, qis-carbon stainless hlau yog ze rau qhov vuam thiab cuam tshuam los ntawm tshav kub. Tsawg decomposed carbides. Yog li ntawd, XiaoZ txo cov pa roj carbon emissions vim carbides tuaj yeem ua rau vuam corrosion. Cov ntsiab lus npib tsib xee ntawm 305 cov khoom yog siab, thiab vim nws qhov qis ua haujlwm hardening tus nqi, nws yog ib qho yooj yim rau tsim. 308 stainless hlau feem ntau yog siv rau kev tsim vuam rods.

3. Kev xaiv ntawm magnesium hmoov.

4. Kev xaiv cov khoom sib khi. Ua ntej, stainless hlau 301 cov khoom siv tawv tawv thaum ua deformation thiab siv ntau yam kev siv zog. Kev tsim cov hlau tsis muaj hluav taws xob cua sov ua los ntawm 304 stainless hlau, dav siv rau cov kua cua sov (tsis muaj zog acidity lossis alkalinity) thiab cua sov. Nws muaj kev ua haujlwm zoo, molding yooj yim, tus nqi nruab nrab, thiab yog siv dav hauv kev tsim cov raj cua sov.
