Dab tsi yog cov khoom ntawm cov txheej txheem tiv thaiv rau alloy cua sov hlau?

Yog tias cov khoom cua sov tsis tawm cov roj uas ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob hluav taws xob thaum siv, kev kho ua ntej oxidation tsis tsim nyog; Yog tias cov pa phem raug tso tawm los ntawm cov khoom siv hluav taws xob hluav taws xob, nws yog qhov zoo tshaj plaws los ua kev kho mob ua ntej oxidation thiab lwm yam kev kho oxidation kom ua rau cov khoom siv hluav taws xob hluav taws xob zoo li lub teeb grey, nrog rau cov khoom tseem ceeb yog aluminium oxide. Cov ntshiab oxide zaj duab xis ntawm nickel chromium hluav taws xob cua sov alloy yog tsaus ntsuab, thiab lub ntsiab tivthaiv yog chromium oxide. This pure oxide film has a dense structure and a high melting point, which tightly adheres to the substrate of the alloy electric heating material and plays a protective role.

Cov oxide zaj duab xis tsim nyob rau saum npoo ntawm lub alloy hluav taws xob cua sov lub caij tsis yog tag nrho raws li cov linear expansion coefficient ntawm alloy hluav taws xob cua sov caij matrix. Cov cua sov ntse thiab cua txias tuaj yeem ua rau tawg thiab txawm tias detachility ntawm cov yeeb yaj kiab dense tense, uas tsis muab kev tiv thaiv tsim nyog.

Kev kho mob ua ntej oxidation yog hais txog cov cua kub ntawm cov khoom siv hluav taws xob hluav taws xob nyob rau hauv lub qhov cub kom qhuav, kom qhov kub thiab txias ntawm cov khoom siv hluav taws xob cua sov yog {{0}}} degrees Celsius hauv qab nws qhov siab tshaj plaws ua haujlwm kub, thiab nws yog khaws cia rau 7-10 teev. Tom qab ntawd, nws maj mam txias nrog lub qhov cub. Piv txwv li, 0Cr25Al5 alloy hluav taws xob cua sov caij tuaj yeem ua kom sov ntawm 1050 degrees Celsius.

Kev ceev faj rau kev siv hluav taws xob rauv hlau:

1. Thaum tsim cov kab hluav taws xob hauv hluav taws xob, txoj hlua hluav taws xob yuav tsum tau ua raws, qhov chaw thauj khoom yuav tsum tsim nyog, thiab txoj kab uas hla ntawm cov hlau yuav tsum raug xaiv kom raug;

2. Pre oxidation ntawm lub cub hluav taws xob hluav taws xob xaim ua ntej siv los txuas nws lub neej kev pab cuam;

3. Cov hluav taws xob hluav taws xob hluav taws xob yuav tsum raug txuas kom raug raws li cov txheej txheem tsim thaiv thaum lub sijhawm teeb tsa;

4. Ua ntej txhim kho cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob, yuav tsum tau ua tib zoo tshuaj xyuas lub tshuab hluav taws xob kom tshem tawm cov ferrite, carbon deposition, thiab tej zaum yuav muaj kev puas tsuaj rau lub cub hluav taws xob, kom tsis txhob muaj luv luv Circuit Court thiab tiv thaiv cov hlau tawg;

5. Ua ntej siv cov hluav taws xob hluav taws xob, qhov rhiab ntawm cov kev tswj qhov kub thiab txias yuav tsum kuaj xyuas kom tsis txhob muaj hluav taws xob hluav taws xob kom hlawv tawm;

6. Nyob rau hauv lub xeev nruj, qhov tsim nyog ua hauj lwm lub xeev stretching piv yog 1: 3;

7. Ua tib zoo saib xyuas kev nyab xeeb ntawm kev siv, ua haujlwm zoo hauv rwb thaiv tsev, thiab tiv thaiv hluav taws xob poob siab.

Kev suav cov nqi cua sov ntawm hluav taws xob rauv hlau: Q=3.62W=3.62PT

Q (J) - Cov cua sov tsim los ntawm lub tshuab hluav taws xob,

W (kwh) - Lub zog hluav taws xob siv los ntawm lub tshuab hluav taws xob,

P (kw) - Lub zog ntawm lub tshuab hluav taws xob,

T (h) - Lub sijhawm hluav taws xob ntawm lub cub hluav taws xob.
