Muaj ntau ntau yam ntawm lub zog tshiab, thiab lawv cov kev siv kuj sib txawv. Yog li ntawd, nyob rau hauv lub xaiv ntawm hluav taws xob cua sov nyob ntawm tej, txawv kuj furnaces yuav tsum tau phim tsim hluav taws xob cua sov nyob ntawm tej. Raws li kev faib tawm cov khoom siv, cov khoom siv hluav taws xob cua sov siv hluav taws xob feem ntau muaj xws li hlau-chromium-aluminium alloy hluav taws xob cua sov hlau thiab nickel-chromium alloy hluav taws xob cua sov hlau. Cov qub yog cov khoom siv hlau nrog cov qauv tsim qauv, thiab qhov tom kawg yog cov khoom siv alloy nrog austenite qauv. Tsis tas li ntawd, muaj qee qhov tshwj xeeb-xaim hluav taws xob cua sov hluav taws xob hlau hluav taws xob xaim xws li tungsten hlau, molybdenum hlau thiab lwm lub thawv-hom ua kom muaj cua sov. Raws li kev siv sib txawv thiab sib txawv kub, qhov hluav taws xob cua sov sib txawv tuaj yeem xaiv tau.
1. Nta ntawm hlau-chromium-aluminium hluav taws xob cua sov hluav taws xob hlau hluav taws xob cua sov alloy cov khoom rau lub thawv hom tsis kam rauv:
1. Kev siv kub yog high school. Piv txwv, qhov siab tshaj plaws siv kub ntawm HRE hlau-chromium-aluminium alloy hlau nyob rau hauv cov huab cua tuaj yeem ncav cuag 1400 ° C, uas yog, qhov kub siab tshaj plaws ntawm lub thawv-hom tiv taus cua sov tuaj yeem ncav cuag 1400 degrees. Yog tias koj xav tsim qauv lub thawv ntim cov thawv tiv thaiv kev ua haujlwm ntau tshaj qhov ntsuas kub no, Koj yuav tsum xaiv lwm lub xov hluav taws xob thaiv hluav taws xob;
2. Kev pab lub neej ntev;
3. Cov pub zoo saum npoo load yog loj;
4. Cov oxidation tsis kam zoo. AI2O3 zaj duab xis tsim tom qab oxidation muaj zoo tshuaj lom neeg thiab siab resistivity, thiab nws lub zog nqus tsawg dua li ntawm nickel-chromium alloy thiab siab resistivity;
5. zoo leej faj;
6. Tus nqi pheej yig dua li uas tau ua ntawm nickel-chromium alloys;
7. Qhov tsis zoo yog tias thaum kub nce, qhov ua tau zoo yog cov yas, thiab lub zog ntawm qhov kub tsis txias yog tsawg.
2. Cov yam ntxwv ntawm lub thawv hom tiv taus cua sov nickel-chromium hluav taws xob cua sov xaim:
1. Muaj zog hauv qab kub;
2. Ua kom txias txias tom qab siv sijhawm ntev, cov khoom siv yuav tsis ua khoob;
3. Cov emissivity ntawm tag nrho oxidized nickel-ming alloy yog siab dua li ntawm cov hlau-chromium-aluminium alloy;
4. Tsis-magnetic;
5. Nyob rau hauv tas li ntawd mus leej faj cua, nws twb zoo xeb kuj.
3. Qhov tsis zoo ntawm lub thawv-hom hluav taws xob ua cua sov hlau hluav taws xob cua sov hlau:
Alloy fais cub tawg hlau yog lub feem ntau lug siv thiab qhov loj tshaj plaws nqi cua sov rau hauv cov ntaub ntawv uas. Nws disadvantage yog hais tias nws yog ib tug heev kub (kub lub xeev) nyob rau hauv kev ua hauj lwm tej yam kev mob, thiab nws yog nws oxidation cov tshuaj tiv thaiv thiab hlawv tawm nyob rau hauv cov huab cua; los ntawm lub foundations ntawm electrothermal zog hloov dua siab tshiab, lub zog yog poob vim lub cim ntawm pom lub teeb; hluav taws xob cua sov ua paug ntau zaus Thaum siv nyob hauv qhov chaw muab kauv, ib qho kev cuam tshuam kev tiv thaiv hluav taws xob yuav tsim tawm thaum lub zog thov.
