Silicon Hniav Tshaj Tawm Ntawm Cov Hlau Silicon Hmoov Ntau Txheej Txheem: Cov kauj ruam tseem ceeb los ntawm cov khoom siv raw rau cov khoom tiav!

Cov khoom siv raw zoo yog lub hauv paus rau kev ua cov hlau zoo hlau Silicon hmoov. Thawj cov ntaub ntawv raw rau kev tsimHlau Silicon HmoovYog Silica Pob Zeb thiab Carbon-Raws li cov neeg sawv cev. Silica pob zeb yuav tsum tau raug xaiv nrog cov ntsiab lus silica siab (feem ntau loj dua los yog sib npaug nrog rau 98%) thiab cov hom tsis huv, pob zeb pob zeb uas suav nrog cov pob zeb quartzite; Cov pa roj carbon-raws li feem ntau yog cov roj hluav taws xob roj av, hluav ncaig hluav taws xob, uas xav tau cov ntsiab lus muaj roj carbon monoxide tsau cov ntsiab lus. Ua ntej nkag mus rau cov txheej txheem ntau lawm, cov khoom siv raw yuav tsum yauv ua pob zeb: Silica pob zeb yog tawg thiab ntsuas kom pom tseeb qhov uas tau tsim nyog, feem ntau tswj tau ntawm 10-50 hli; Cov pa roj carbon-raws li cov neeg sawv cev tseem tsoo thiab tshuaj ntsuam, tiv thaiv kev cuam tshuam nrog kev cuam tshuam nrog cua sov thiab tshuaj lom neeg hauv cov txheej txheem tom ntej.

Smelting yog cov txheej txheem tseem ceeb hauv kev tsim cov khoom silicon hmoov, feem ntau nqa tawm siv hluav taws xob arc. Ua ntej kho silica thiab cov pa roj carbon-raws li cov neeg sawv cev sib cais tau sib xyaw rau hauv cov kev sib piv thiab ntxiv rau cov hluav taws xob ua kom sov sov. Nyob rau hauv cov kub (1800-2000 degree), sidle nyob rau hauv lub silica reacts siv cov pa roj carbon-raws li cov pa silicon uas muaj cov ntshav thiab cov pa roj carbon monoxide. Thaum lub sij hawm cov tshuaj tiv thaiv xws li electrode txoj hauj lwm yog tswj hwm tus nqi pub mis thiab tshuaj lom neeg nyob rau hauv cub tawg. Tom qab lub sijhawm smelting, cov khoom silicon accumulates hauv qab ntawm lub cub tawg. Thaum muaj ntau yam txaus tau mus txog, Molten Silicon yog rho tawm thiab nrum rau hauv silicon ingots. Thaum lub sij hawm fais fab arc rauv zom zom cov txheej txheem, huab cua sov thiab txias yuav tsum tsis txhob muaj kev sib kis rau cov hlau uas muaj sia.

Silicon Ingots nrum los ntawm cov hluav taws xob arc yuav tsum ua ntxiv mus rau hauv cov hmoov daim tawv. Ua ntej, ib lub crusher yog siv los rhuav cov silicon kev cuam tshuam rau hauv cov ntawv me me, nrog cov crushon block feem ntau yog li 20 txog 100 hli. Lub crushed silicon block yog tom qab ntawd noj rau hauv kev sib tsoo cov khoom siv rau kev ua ntxiv. Cov khoom siv sib tsoo uas suav nrog cov pob zeb mills thiab raymond mills. Thaum sib tsoo cov txheej txheem, tsis raug xws li sib tsoo lub sijhawm, hom, thiab kom muaj nuj nqis ntawm kev sib tsoo xov yog tswj tau kom zom cov silicon block rau hauvHlau Silicon Hmoovntawm qhov xav tau qhov loj me. Yuav kom tau hlau silicon hmoov nrog uniform partlele loj, cov khoom hauv av txuas ntxiv kom tshem tawm cov khoom uas tsis tau raws li qhov loj me me. Feem ntau, cov particle loj ntau ntau ntawm cov hlau silicon hmoov yog nyob nruab nrab ntawm 80 thiab 325 mesh.

Kom tau raws li cov kev xav tau ntawm cov hlau silicon hmoov rau kev lag luam sib txawv, hauv avHlau Silicon Hmoovfeem ntau undergoes kev kho mob huv si. Cov hau kev ua kom huv xws li cov tshuaj purification thiab kev ua kom lub cev. Tshuaj lom neeg puricification feem ntau yog xim hlau thiab tsis yog xim hlau impurities xws li hlau silicon hmoov los ntawm cov kua qaub qaub, thiab lwm txoj hauv kev; Kev ua kom lub cev ua kom lub cev ua haujlwm zoo li kev sib cais sib sib zog nqus thiab lub ntiajteb qhuav zog sib cais, siv cov khoom sib txawv ntawm lub cev ntawm lub cev thiab silicon kom cais impurities. Thaum lub sij hawm cov txheej txheem lim dej, cov txheej txheem tsis yuav tsum tau nruj me ntsis kom ntseeg tau tias qhov tsis txaus siab tau raug tshem tawm yam tsis muaj kev cuam tshuam ntawm cov hlau silicon hmoov. Lim hlau silicon silicon hmoov yuav tsum tau yov ua tau zoo, nrog cov ntsiab lus ntsuas tshuaj, sicurity cov ntsiab lus, thiab lub cev ntom ntom, wangability, thiab lwm yam). Tsuas yog Hlau Silicon Hmoov Uas tau raws li txhua tus qauv zoo tuaj yeem ntim tau thiab muag li cov khoom tiav.

Tiav Hlau Silicon Hmoov yog feem ntau ntim rau hauv cov thawv ntim khoom kom tiv thaiv kev nqus dej noo, oxidation, lossis paug thaum lub sijhawm tsheb thauj mus los. Cov ntaub ntawv ntim ntim muaj xws li hnab yas ntaub pua rooj thiab cov hnab ntim ntawv sib sau ua ke, feem ntau yog 25 kg ib lub hnab lossis 50 kg ib lub hnab. Ntim pob zeb Silicon hmoov yuav tsum muab khaws cia rau hauv cov av ntim khoom, kom deb ntawm cov tshuaj ntub dej thiab cov tshuaj tua hluav taws thiab cov cua sov kom tiv thaiv hluav taws lossis tawg. Thaum lub sij hawm cia, chaw kuaj xyuas tsis tu ncua yuav tsum tau ua rau cov khoom lag luam kom paub tseeb zoo.
