Lub zog ua haujlwm ntawm DC hloov hluav taws xob siv rau kev sib nqus induction cua sov siv rau cov khoom sib nqus induction yuav tsum tau kho.
Siv cov nyhuv Joule ntawm cov hluav taws xob ntws los hloov hluav taws xob hluav taws xob rau hauv lub zog rau cov khoom cua sov. Nws feem ntau muab faib ua tam sim ntawd resistor cua sov thiab indirect resistor cua sov. Lub zog hluav taws xob hluav taws xob ntawm hom yav dhau los yog tam sim no siv rau cov khoom siv hluav taws xob, thiab thaum muaj hluav taws xob ntws dhau los, cov khoom cua sov nws tus kheej (xws li hluav taws xob cua sov thiab tshuab ironing) yuav kub. Cov khoom uas tuaj yeem ua kom sov tam sim ntawd los ntawm tus resistor yuav tsum yog ib qho hluav taws xob conductor, tab sis nws muaj kev tiv thaiv ntau dua. Vim lub tshav kub generated los ntawm cov khoom rhuab nws tus kheej, nws belongs rau cov cua sov sab hauv thiab muaj ib tug high thermal efficiency. Indirect resistor cua sov yuav tsum muaj cov khoom siv hlau lossis cov khoom tsis yog xim hlau los ua rau cov khoom siv cua sov. Lub zog tsim los ntawm cov khoom cua sov yog xa mus rau cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob, thermal convection, thiab kev sib kis. Vim tias cov khoom cua sov thiab cov khoom siv cua sov tau muab faib ua ob ntu, cov khoom siv cua sov feem ntau tsis txwv thiab kev ua haujlwm tiag tiag yog qhov yooj yim.
Indirect resistors feem ntau yog siv los ua raw khoom rau cov khoom siv cua sov, nrog kev ua haujlwm siab, tsis tshua muaj kub coefficient ntawm resistors, me me deformation ntawm qhov kub thiab txias, thiab tsis tshua muaj kev laus. Cov ntaub ntawv uas tsis yog xim hlau muaj xws li hlau aluminium alloy profiles, nickel chromium thiab lwm yam khoom siv hlau sib xyaw, cov khoom siv carbon carbon, thiab molybdenum disilicide. Kev khiav hauj lwm kub ntawm cov khoom siv hlau kub yuav tsum ncav cuag 1000-1500 degree nyob ntawm seb hom khoom siv raw; Kev khiav hauj lwm kub ntawm cov khoom tsis yog xim hlau cov khoom kub nce mus txog 1500-1700 degree . Hom tom kawg yog ib qho yooj yim rau nruab thiab tuaj yeem hloov tau los ntawm lub tshuab hluav taws xob, tab sis nws yuav tsum yog cov khoom siv hluav taws xob hloov pauv thaum lub sijhawm ua haujlwm. Nws cov kev pab cuam lub neej yog luv dua li ntawm aluminium alloy cua sov Cheebtsam. Nws yog feem ntau siv nyob rau hauv high-temperature electric furnaces, qhov chaw uas qhov kub thiab txias tshaj qhov tso cai rau kev khiav hauj lwm kub ntawm hlau puas cua sov Cheebtsam, thiab ib co tshwj xeeb qhov chaw.
Sib nqus induction cua sov
Cov nyhuv thermoelectric tsim los ntawm induced electromotive quab yuam (vortex) ntawm ib tug hluav taws xob conductor nyob rau hauv ib tug alternating magnetic teb ua rau tus neeg xyuas pib kom sov nws tus kheej. Raws li cov txheej txheem cua sov sib txawv, qhov zaus ntawm AC siv rau kev sib nqus induction cua sov suav nrog tam sim no ncaj qha (50-60 Hz), zaus siab (60-10000 Hz), thiab siab zaus (dhau 10000 Hz). DC hloov hom fais fab mov yog AC fais fab tso tawm hauv kev lag luam kev lag luam, thiab feem ntau ntawm DC hauv Suav teb yog 50 Hz thoob ntiaj teb. Lub zog ua haujlwm ntawm DC hloov hluav taws xob siv rau kev sib nqus induction cua sov siv rau cov khoom sib nqus induction yuav tsum tau kho. Raws li qhov tso zis hluav taws xob loj ntawm cov cuab yeej siv cua sov thiab qhov ntim loj ntawm lub zog hluav taws xob network, DC lub zog hluav taws xob siab (6-10KV) tuaj yeem siv los muab lub zog rau lub tshuab hloov pauv; Cov cuab yeej siv tshuab cua sov tuaj yeem txuas tau tam sim ntawd rau 380V hauv qab hluav taws xob hluav taws xob hluav taws xob.
