Distribution Technology rau Silicon Smelting

Hluav taws xob arc rauv yog ib yam khoom siv hluav taws xob uas tsim los ntawm hluav taws xob arc kom sov. Nyob rau hauv cov txheej txheem ntawm cov tshuaj silicon smelting, lub cev thiab tshuaj hloov pauv yog ze ze rau cov tshuab hluav taws xob. Qhov zoo ntawm kev faib hluav taws xob ua haujlwm muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm smelting. Lub arc feem ntau muaj nyob rau ntawm qhov kawg hluav taws xob, thiab cov kab noj hniav yog raug cuam tshuam thiab thrust ntawm lub arc, uas qhib cov khoom ob txhais ceg thiab tsim ib lub teeb duab. Thaum lub sij hawm smelting txheej txheem, kev tswj cov hluav taws xob tsis zoo ntawm lub tshuab hluav taws xob hluav taws xob yog ua tiav los ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob. Feem ntau, nws yog los tswj qhov tob ntawm electrode embedding. Pem hauv ntej faus electrodes feem ntau qhia tau hais tias muaj ntau tshaj ntawm kev txo tus neeg sawv cev, tsim cov nplaim taws nyob ze ntawm lub electrode, suab nrov arc, tsis tshua muaj silicon kub, tsis muaj ntau, thiab siab zog noj. Sib sib zog nqus faus electrodes, yog hais tias muaj tsawg heev txo tus neeg sawv cev nyob rau hauv lub cub tawg khoom, lub electrode yuav nyob rau hauv ib tug qis txoj hauj lwm. Vim tias qhov kev tiv thaiv ntawm lub qhov cub hluav taws xob nce ntxiv nrog qhov txo qis ntawm cov pa roj carbon monoxide, qhov nce hauv qhov tsis kam ua rau txo qis ntawm cov khoom siv tam sim no, nce hauv electrode noj, thiab txo cov khoom lag luam. Hauv kev tsim khoom, qhov faus qhov tob ntawm electrodes yog txiav txim siab raws li kev ua haujlwm ntawm qhov chaw. Kho qhov tob ntawm electrode embedding yog txoj hauv kev zoo tshaj plaws los kho lub tshuab hluav taws xob los ntawm kev hloov cov nqi ntawm cov khoom siv hluav taws xob. Thaum qhov hluav taws xob theem nrab ntawm lub cub hluav taws xob ntau tshaj ib qho nqi, cov electrodes yuav raug puas tsuaj, volatilization poob ntawm silicon yuav nce, thiab sab sauv ntawm lub cub tawg yuav overheat, ua rau kom kub poob. Qhov thib ob tam sim no yog txwv los ntawm qhov tso cai tam sim no ntom ntom ntawm cov electrode thiab tsis tuaj yeem nce ntxiv.
Qhov piv ntawm tam sim no rau qhov voltage yog qhov tseem ceeb hauv kev ua haujlwm ntawm lub cub tawg. Yog tias qhov tam sim no rau qhov voltage piv tsawg dhau, cov electrode tsis tuaj yeem raug tshem tawm, ua rau nws nyuaj rau kev lag luam qhib arc ntau lawm. Qhov tam sim no rau voltage piv yog siab dhau lawm, cov electrode yog ntxig rau hauv cov khoom siv rau hauv qhov cub, thiab cov khoom siv tsis zoo heev. Hauv kev tsim khoom, tsuas yog thaum pom qhov tsim nyog tam sim no rau qhov ntsuas hluav taws xob, qhov kev ua haujlwm tam sim no ruaj khov, cov khoom sib npaug, thiab cov electrode txawm tsa los yog qis dua, tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Kho qhov ua haujlwm voltage yog ib qho tseem ceeb ntawm kev kho cov khoom tsim ntawm lub cub tawg. Kev ua haujlwm voltage ntawm lub cub tawg nyob ntawm ob yam: ntawm ib sab, cov qauv luv luv yuav tsum muaj hluav taws xob zoo thiab tsim nyog lub zog. Ntawm qhov tod tes, nws yog qhov kev mob ntawm lub cub tawg, nrog rau cov qauv ntawm lub cub tawg thiab kev ua haujlwm ntau lawm. Tus nqi tsis kam ntawm kev ua haujlwm ua haujlwm thaum lub sij hawm smelting yog qhov tseem ceeb, thiab nws yooj yim los hloov. Kev siv zog yuav tsum tau ua kom ruaj khov thiab ua kom muaj txiaj ntsig zoo. Feem ntau, txhawm rau xyuas kom meej cov khoom siv qhov kub thiab txias, nce qhov voltage. Qhov kub ntawm cov khoom siv rau lub pob no yog nyob ib ncig ntawm 600 ° C. Thaum siv cov khoom siv raw uas ua tau raws li cov lus qhia tshwj xeeb, qhov loj dua qhov me me ntawm cov khoom siv rau hauv qhov cub, qhov me dua qhov tsis kam, qhov siab dua ntawm cov ceg tam sim no, thiab qhov tsawg dua cov electrode. nkag mus.
