Smelting txheej txheem ntawm silicon rau chemical kev lag luam
Cov txheej txheem ntawmtshuaj siliconsuav nrog kev npaj them nqi, hluav taws xob rauv melting, silicon refining thiab casting, thiab crushing los ntawm kev tshem tawm slag suav nrog. Tag nrho cov khoom siv raw yog kho raws li qhov tsim nyog ua ntej kev npaj them nqi. Cov silica yog tawg nyob rau hauv lub puab tsaig crusher mus rau ib tug lumpiness ntawm tsis ntau tshaj 100 hli, thiab cov fragments tsawg tshaj li 5 hli yog soj ntsuam tawm thiab ntxuav nrog dej. Vim hais tias cov fragments nyob rau hauv lub cub tawg melts nyob rau hauv lub Upper ib feem ntawm lub cub tawg, lub permeability ntawm tus nqi yog txo, ua rau cov txheej txheem ntau lawm nyuaj rau nqa tawm. Petroleum coke muaj ib tug high conductivity, yuav tsum tau tawg mus rau ib tug lumpiness ntawm tsis ntau tshaj 10 hli, tab sis kuj yuav tswj cov roj av coke hmoov. Vim nws qhov hluav taws xob hluav taws xob ncaj qha ntawm lub qhov ncauj ntawm lub qhov cub, nws yuav ua rau tus neeg ua haujlwm tsis txaus.
Hauv kev tsim cov tshuaj silicon, bituminous thee tuaj yeem hloov cov hluav taws xob tag nrho, xws li Hunan Zhuzhou zoo ntxuav bituminous thee, tsau carbon mus txog 77.19%, volatile feem 19.4%, tshauv ntsiab lus 3.41%, Fe2O3 cov ntsiab lus 0.22%, Al2O3 cov ntsiab lus 0.99%, CaO cov ntsiab lus 0.17%. Los ntawm kev xyaum ua ntau lawm, nws muaj peev xwm siv hom bituminous thee rau smelt tshuaj silicon.
Ntoo blocks thiab chips rau zus tau tej cov tshuaj silicon yog ua los ntawm cov ntoo cutters thiab chippers. Cov pa roj carbon tsawg tus neeg sawv cev hauv kev them nqi yog cov roj av coke thiab cov roj av bituminous, thiab cov nqi ntawm cov ntoo thaiv thiab cov nti ntoo nyob ntawm qhov chaw ua kom sov. Ntau lawm tsis siv ntoo, tab sis cov khoom zoo yog ruaj khov dua. Qhov piv ntawm tus nqi yog txiav txim raws li cov khoom qib yuav tsum tau ua. Qhov piv ntawm roj av coke mus rau bituminous thee yog txiav txim raws li tus nqi ntawm cov pa roj carbon monoxide yuav tsum tau rau txhua batch ntawm ore silicon. Qhov piv ntawm cov roj av coke rau cov thee bituminous muaj kev cuam tshuam zoo rau kev ua haujlwm tsis kam ntawm tus nqi.
Tom qab ntsuas txhua yam ntawm tus nqi, tus nqi sib tov sib npaug, thiab tom qab ramming lub qhov cub, cov nqi sib xyaw sib xyaw yog concentrated rau hauv lub qhov cub. Khaws ib qib ntawm cov khoom siv, ntxiv qhov sib npaug.
Cov tshuaj siliconntau lawm yog nruam. Cov xwm txheej hauv lub qhov cub tsis tas mus li.
Kev tsim cov tshuaj silicon yog cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob mus rau hauv lub zog hluav taws xob hauv lub tshuab hluav taws xob, thiab tom qab ntawd ncaj qha cua sov cov khoom siv hluav taws xob los tsim cov tshuaj tiv thaiv. Yog li ntawd, cov yam ntxwv ntawm cov hluav taws xob nyob rau hauv lub cub tawg yog ib qho tseem ceeb heev, smelting kev siv ntawm kaw arc ua hauj lwm, tuav ib tug kub kub rauv, txhim kho thermal efficiency, txhim kho tus nqi ntawm hluav taws xob rauv, nyob rau hauv txoj kev tshawb no muaj peev xwm ntawm 3200KVA thiab 6300KVA hlau silicon. rauv txhua. Lub smelting yog nqa tawm los ntawm txoj kev ua hauj lwm ntawm braising rau ib lub sij hawm ntawm lub sij hawm thiab tsis tu ncua concentrated noj. Nyob rau hauv ib txwm muaj xwm txheej, nws yog ib qho nyuaj rau cia li tso tus nqi, thiab nws yog feem ntau tsim nyog los yuam sedimentation. Lub tshuab cua sov hloov pauv tau yooj yim thiab nyuaj rau tswj. Yog li ntawd, hauv kev tsim khoom yuav tsum raug txiav txim siab, kho raws sijhawm. Txhua txhua 4 teev tawm ntawm qhov cub, rau qhov tseeb casting, crushing thiab slag sorting rau hauv cia.
