Yuav ua li cas kom lub cub tawg hluav taws xob ua haujlwm ruaj khov thaum siv

Txhawm rau kom muaj kev ruaj ntseg siab tshaj plaws thiab kev ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob hauv cov khoom siv. Ua ntej yuav cov khoom siv hluav taws xob hluav taws xob hauv kev ua lag luam, nws yog ib qho tsim nyog yuav tsum xav txog kev ua haujlwm thiab ib puag ncig ntawm cov khoom siv, thiab tom qab ntawd txiav txim siab seb puas yuav xaiv cov nickel chromium lossis hlau chromium aluminium electric furnace wires. Vim hais tias hluav taws xob rau hluav taws xob ntawm cov hlau sib txawv muaj ntau yam kev siv, lawv yuav tsum tau paub qhov txawv. Tsuas yog nyob rau hauv txoj kev no nws tuaj yeem ua haujlwm ruaj khov thiab ua tau zoo.

Cov yam ntxwv ntawm nickel chromium hluav taws xob rauv hlau yog:

1. Lub zog muaj zog ntawm qhov kub thiab txias;

2. Tom qab siv lub sij hawm ntev thiab txias ntxiv, cov khoom yuav tsis nkig;

3. Tus nqi hluav taws xob ntawm tag nrho oxidized npib tsib xee alloy yog siab dua li ntawm cov hlau chromium aluminium alloy;

4. Tsis muaj hlau nplaum;

5. Dhau li ntawm huab cua huab cua, nws muaj kev tiv thaiv corrosion zoo.

Cov yam ntxwv ntawm hlau chromium txhuas hluav taws xob rauv hlau hluav taws xob cua sov alloy khoom yog:

1. Kev siv kub siab, xws li qhov siab tshaj plaws kev siv kub ntawm HRE hlau chromium aluminium alloy hlau nyob rau hauv qhov chaw tuaj yeem ncav cuag 1400 degree;

2. Lub neej ua haujlwm ntev;

3. Qhov tso cai rau saum npoo yog siab;

4. Kev ua haujlwm zoo antioxidant, thiab AI2O3 zaj duab xis tsim tom qab oxidation muaj cov tshuaj tiv thaiv zoo thiab muaj zog tiv taus;

5. Qhov tshwj xeeb lub ntiajteb txawj nqus tsawg dua nickel chromium alloy;

6. Siab resistivity;

7. Zoo sulfur tsis kam;

8. Tus nqi yog qis dua nickel chromium alloy;

9. Qhov tsis zoo yog tias qhov kub nce, nws nthuav tawm plasticity thiab tsis muaj zog ntawm qhov kub thiab txias.

Cov saum toj no piav qhia txog cov yam ntxwv ntawm nickel chromium hluav taws xob rauv hlau thiab hlau chromium txhuas hluav taws xob rauv hlau. Cov hluav taws xob hauv hluav taws xob muaj qhov zoo elasticity, siab tiv taus, lub zog zoo thaum cua sov, tsis yooj yim rau oxidize nyob rau hauv qhov kub thiab txias, thiab muag ntawm tus nqi qis. Txawm li cas los xij, cov hlau nplaum hluav taws xob hluav taws xob nws tus kheej nyob rau hauv qhov kub thiab txias (kub lub xeev) thaum lub sijhawm ua haujlwm, thiab nws yooj yim rau oxidation cov tshuaj tiv thaiv thiab hlawv hauv huab cua. Los ntawm qhov kev xav ntawm hluav taws xob hloov dua siab tshiab, lub zog poob yog tshwm sim los ntawm lub cim ntawm ib co pom lub teeb; Cov kab hluav taws xob hauv hluav taws xob feem ntau siv nyob rau hauv lub xeev kauv, thiab thaum muaj zog, lawv yuav tsim cov nyhuv inductive impedance. Hlau chromium aluminium siab tiv thaiv hluav taws xob cua sov alloys muaj cov yam ntxwv ntawm kev ua haujlwm siab, tsis tshua muaj siab kub coefficient, thiab kev siv siab kub. Zoo corrosion kuj ntawm qhov kub thiab txias, tshwj xeeb tshaj yog tsim rau siv nyob rau hauv cov huab cua uas muaj leej faj thiab sulfides, thiab ntawm tus nqi qis, nws yog ib qho zoo tagnrho cov khoom cua sov rau industrial furnaces, khoom siv hauv tsev, thiab far-infrared.
