Kev ua tau zoo thiab cov yam ntxwv ntawm quartz radiating tubular hluav taws xob cua sov ntsiab lus

① High hluav taws xob efficiency. Lub spectral emissivity ntawm quartz hluav taws xob raj zoo li hluav taws xob cua sov ntsiab yog siab li 90% -92%, thiab lawv cov hluav taws xob efficiency siab li 90%, thaum lub hluav taws xob efficiency ntawm lwm cov hluav taws xob hluav taws xob cua kub ntsiab lus feem ntau tsuas yog 62%. -80%.

② Kev ruaj ntseg zoo. Quartz muaj cov coefficient qis heev ntawm kev nthuav dav thiab ua haujlwm zoo heev rau cov cua kub ceev thiab txias, tab sis tsis muaj kev pheej hmoo ntawm kev tawg. Nyob rau tib lub sijhawm, quartz muaj cov hluav taws xob rwb thaiv tsev zoo thiab tsis muaj hygroscopicity ntawm qhov kub thiab txias, yog li nws tuaj yeem ua haujlwm nyab xeeb thiab ntseeg tau hauv qhov chaw ntub dej.

③ Tsawg tshav kub tsis kam, pib ceev ceev, thiab tsawg dua cov cua sov tom qab fais fab tuag.

④ Lub teeb yuag. Quartz radiation tube zoo li lub tshuab cua sov yog 1/3 txog 1/7 ntawm qhov hnyav ntawm cov hlau raj zoo li cov cua sov thiab cov khoom siv silicon carbide.

⑤ Lub neej ua haujlwm ntev.

1. Arc cua sov

(1) Siv hluav taws xob arc nruab nrab ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob kom ncaj qha rau cov khoom siv hluav taws xob, xws li hluav taws xob arc steelmaking rauv;

(2) Siv cov arc ntawm electrodes rau indirectly yaj cov khoom siv rauv, xws li steelmaking arc rauv;

(3) Siv lub zog thermal hloov los ntawm kev tiv thaiv thiab arc kom ua tiav cov khoom siv hluav taws xob zoo, xws li submerged arc furnaces.

2. Induction cua sov

Cov cua sov yog ua los ntawm qhov poob tam sim no los yog hysteresis poob tsim hauv ib tus neeg xyuas pib muab tso rau hauv qhov chaw sib nqus sib nqus. Nws tau muab faib ua ob hom raws li cov qauv: nrog ib tug tub ntxhais thiab tsis muaj ib tug tub ntxhais, thiab peb hom raws li cov zaus: hwj chim zaus, nruab nrab zaus, thiab siab zaus.

3. Cov cua kub nruab nrab

Cua sov los ntawm kev siv qhov poob ntawm dielectric nyob rau hauv alternating hluav taws xob teb.

4. Kev tiv thaiv cua sov

(1) Electrify cov khoom rhuab thiab ncaj qha tshav kub nws siv lub tshav kub generated los ntawm Joule nyhuv;

(2) Thaum tshav kub kub ua kom sov cov khoom los ntawm hluav taws xob, conduction, convection, lossis kev xav.

5. Infrared cua sov

Siv 300; 30000092 xov tooj cua yoj cua sov cov ntaub ntawv uas tsis yog-conductive.

6. Electron beam cua sov

Siv cov kab hluav taws xob los ua cov khoom tawg hauv lub tshuab nqus tsev rau cua sov.
