Arc Kaw Kev Ua Haujlwm Ntawm Hlau Silicon

Lub kaw arc kev ua haujlwm yog kom tsim nyog embed cov electrode rau hauv cov khoom siv rau hauv qhov cub, siv cov khoom siv hluav taws xob semi molten ua cov tshuaj tiv thaiv thaiv, thiab tsim kom muaj ib qho arc nruab nrab ntawm cov electrode thiab cov khoom siv hluav taws xob molten. Txhawm rau kom ua tiav qhov kaw arc, thawj qhov yuav tsum xav txog yog txoj kev pub mis. Txoj kev pub mis muaj xws li pub mis ib zaug, pub mis noj, thiab pub ntau yam. Tsuas yog rau ib qho kev txhaj tshuaj pub mis uas yog kev ua haujlwm qhib arc, tag nrho lwm txoj hauv kev tuaj yeem ua tiav cov haujlwm kaw. Hauv kev tsim cov tshuaj silicon, peb tau txais cov txheej txheem pub mis, uas muaj cov txheej txheem cov khoom ruaj khov, tsis muaj zog noj, thiab lub neej ntev ntawm lub cub tawg. Ntau qhov teeb meem yuav tsum tau hais thaum lub sijhawm ua haujlwm: ua ntej, nws yog qhov tsim nyog los xaiv cov khoom siv hluav taws xob tsim nyog kom cov electrodes tuaj yeem muab tso rau hauv cov khoom txheej ntawm qhov tob tsim nyog; Qhov thib ob yog nrhiav txoj hauv kev los tswj qhov tshwj xeeb tsis kam ntawm cov khoom siv rau hauv qhov cub kom zoo; Thib peb, qhov loj me me ntawm cov khoom siv rau hauv qhov cub muaj qhov cuam tshuam loj rau cov smelting ntawm silicon, thiab ob qho tib si loj thiab me me dhau los ua rau muaj kev puas tsuaj rau lub cub tawg. Qhov zoo ntawm kev ua haujlwm arc kaw yog: ① cov qauv ntawm cov khoom txheej hauv lub cub tawg tuaj yeem tsim ua tiav, thiab cov khoom siv rau hauv qhov cub tawg ua ntu zus; ② Lub teeb arc tsis raug, thiab cov hluav taws xob hluav taws xob poob ntawm cov khoom nto yog txo qis heev. Los ntawm kev tswj xyuas qhov kub ntawm qhov cub tawg, lub thermal efficiency yog txhim kho, yog li ua kom ntau lawm, txhim kho cov khoom zoo, thiab txo lub zog noj Nws tuaj yeem ua tiav cov khoom siv hluav taws xob sib npaug thiab ruaj khov, tsis txhob muaj kev sib tsoo ntawm qhov sib tsoo qhov kub ntawm cov khoom nto yog qhov tsawg, uas ua rau thermal corrosion tsawg dua rau cov khoom siv ntawm cov khoom siv saum npoo, ua kom lub neej ntev ntawm cov cuab yeej siv, thiab txhim kho qhov kev siv ntawm cov khoom siv hluav taws xob hauv hluav taws xob tsawg dua tuaj yeem muab qhov chaw ua haujlwm zoo dua rau kev ua haujlwm ntawm lub cub tawg. Txawm hais tias qhov luaj li cas ntawm lub cub tawg, ntev npaum li kev ntsuas tsim nyog, kev ua haujlwm arc kaw tuaj yeem ua tiav kom ua tiav cov txiaj ntsig zoo tshaj plaws.
