Aluminium refining tus neeg sawv cev, tseem hu ua aflux, yog ib qho tseem ceeb ntawm cov txheej txheem ntawm refining aluminium.Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom huv ntawm cov molten aluminium thiab tshem tawm impurities los txhim kho qhov zoo ntawm cov khoom kawg.
Lub hom phiaj tseem ceeb ntawm tus neeg saib xyuas kev ua kom zoo ntawm txhuas yog los pab txhawb kev tshem tawm ntau yam impurities tam sim no hauv txhuas, xws li magnesium, silicon, thiab lwm yam hlau tsis huv.Cov impurities no tuaj yeem cuam tshuam tsis zoo rau txhua yam khoom, zoo li, thiab kev ua tau zoo ntawm txhuas txhuas.
Aluminium refining agents feem ntau yog tsim los ntawm kev sib xyaw ntawm cov ntsev thiab cov tshuaj fluoride.Cov kev xaiv ntawm cov tebchaw tshwj xeeb nyob ntawm qhov impurities tam sim no thiab qhov xav tau ntawm cov txheej txheem refining.Feem ntau siv cov tshuaj xws li cryolite (Na3AlF6), fluorspar (CaF2), alumina (Al2O3), thiab ntau cov ntsev.
Thaum cov txhuas refining tus neeg sawv cev yog nkag mus rau hauv lub molten aluminium, nws tsim ib txheej ntawm slag rau ntawm qhov chaw.Lub slag ua raws li kev tiv thaiv kev tiv thaiv ntawm cov hlau molten thiab cov cua nyob ib puag ncig.Qhov kev thaiv no ua haujlwm rau ntau lub hom phiaj.Ua ntej, nws tiv thaiv cov txhuas los ntawm kev sib cuag nrog oxygen, yog li txo qhov yuav tshwm sim ntawm oxidation.Tsis tas li ntawd, cov slag txheej txhawb kev sib cais ntawm impurities los ntawm molten aluminium, tso cai rau lawv kom yooj yim tshem tawm.
Cov txheej txheem refining yuav tsum ua tib zoo tswj qhov kub thiab muaj pes tsawg leeg ntawm molten aluminium kom ua tau zoo ntawm cov neeg ua haujlwm zoo ntawm aluminium refining.Raws li cov impurities react nrog cov flux, lawv tsim cov tebchaw uas muaj cov ntsiab lus melting ntau dua li cov moltenaluminium.Yog li ntawd, cov tebchaw no nkag mus rau hauv qab ntawm lub crucible los yog ntab mus rau sab saum toj li dross, ua rau nws yooj yim dua cais lawv los ntawm purified aluminium.
Tus nqi ntawm aluminium refining tus neeg sawv cev yuav tsum tau nyob ntawm ntau yam, xws li muaj pes tsawg leeg thiab ntau yam ntawm impurities, qhov xav tau qib ntawm purity, thiab cov txheej txheem refining tshwj xeeb ua haujlwm.Nws yog ib qho tseem ceeb kom muaj kev sib npaug ntawm kev siv cov flux txaus kom ua tiav kev ua kom huv si thaum txo cov nqi tsawg.
Kev ua tiav daim ntawv thov ntawm tus neeg sawv cev ua kom zoo aluminium ua rau muaj kev ua kom huv si nrog cov khoom siv kho kom zoo, txhim kho qhov chaw tiav, thiab txo qhov cuam tshuam rau qhov tsis xws luag.Lub refined aluminium ces siv tau nyob rau hauv ntau yam kev lag luam, xws li tsheb, aerospace, kev tsim kho, ntim, thiab hluav taws xob.
Hauv cov ntsiab lus, tus neeg sawv cev ntawm txhuas refining yog ib qho tseem ceeb ntawm cov txheej txheem aluminium refining.Nws tso cai rau kev tshem tawm cov impurities, txhim kho qhov zoo ntawm cov khoom kawg, thiab ua kom cov txhuas ua tau raws li cov qauv tsim nyog rau nws cov ntawv thov.
