Hlau Silicon 421

Industrial silicon: Muaj silicon, tseem hu ua metallic silicon, yog ib yam khoom smelted nyob rau hauv lub submerged arc rauv los ntawm silica (lub ntsiab tivthaiv yog silicon dioxide) thiab ib tug carbonaceous txo tus neeg sawv cev.

Cov ntsiab lus ntawm cov khoom tseem ceeb ntawm silicon yog li 98%, thiab cov khoom tsis huv yog hlau, txhuas, calcium, thiab lwm yam. Muaj silicon tuaj yeem muab faib ua 8 qib raws li lub teb chaws tus qauv (GBT2881-2014), xws li 5530 #, 4410#, 4210#, 3303#, thiab lwm yam.

Cov qib muaj cov cim ntawm cov khoom silicon thiab 4 tus lej.

4 tus lej feem qhia qhov siab tshaj plaws cov ntsiab lus ntawm lub ntsiab impurity ntsiab hlau, txhuas, thiab calcium nyob rau hauv cov khoom. Cov ntsiab lus hlau thiab cov ntsiab lus txhuas coj mus rau ib tus lej, thiab cov ntsiab lus calcium siv ob qhov zauv.

Piv txwv li, Si5530 qhia tias cov ntsiab lus hlau tsawg dua los yog sib npaug rau 0.5%, cov ntsiab lus aluminium tsawg dua lossis sib npaug rau 0.5%, thiab calcium Cov ntsiab lus tsawg dua lossis sib npaug li 0.30%. Ntawm ntau qib ntawm kev lag luam silicon, tam sim no, Si4210 muaj qhov xav tau loj, thiab Si5530 tau siv ntau dua.

Lub subdivided khoom ntawm industrial silicon feem ntau muab faib ua polysilicon, organosilicon, thiab alloy silicon.

Nws siv tau dav heev thiab tuaj yeem siv los ua cov ntaub ntawv tseem ceeb ntawm silicon-aluminium thiab silicon-based alloys, organosilicon, thiab polysilicon.

Cov ntawv thov hauv qab tau nkag mus rau ntau yam kev lag luam xws li kev tiv thaiv hauv tebchaws thiab tub rog, kev lag luam ntaub ntawv, lub zog tshiab, thiab lwm yam.

Cov kev siv tshwj xeeb muaj xws li:

1. Cov ntaub ntawv refractory: Cov khoom siv silicon muaj cov yam ntxwv ntawm qhov kub thiab txias thiab tuaj yeem siv los tsim cov khoom siv refractory xws li refractory bricks thiab refractory ceramics, uas yog siv rau hauv kev lag luam xws li hlau, nonferrous hlau, thiab tshuaj lom neeg;

2. Kev lag luam pob zeb: Nws cov khoom siv ntxiv microsilica hmoov tuaj yeem siv rau hauv pob zeb los txhim kho lub zog thiab kav ntev ntawm pob zeb;

3. Ua silicon-aluminium alloys: Ntxiv silicon thaum lub sij hawm casting txheej txheem ntawm txhuas alloys yuav txhim khu lub high-kub fluidity thiab hnav tsis kam ntawm cov alloy, thaum txo tus nqi shrinkage thiab kub cracking nyiam. Silicon-muaj aluminium alloys tuaj yeem siv rau hauv kev tsim cov cav tsheb, cov khoom siv hauv tsev, tsheb log, thiab lwm yam;

4. Ua cov hlau: Nws tuaj yeem txhim kho qee yam khoom ntawm cov hlau;

5. Kev tsim kho qhov muag fibers: Nws yog ib qho tseem ceeb raw cov ntaub ntawv rau optical fibers;

6. Rau kev siv hauv kev lag luam photovoltaic thiab kev lag luam hluav taws xob: Polysilicon yog ib qho tseem ceeb raw khoom rau kev lag luam photovoltaic thiab semiconductor. Hlau silicon tuaj yeem ua kom huv ntxiv los npaj polysilicon, uas yog siv los tsim cov hnub ci vaj huam sib luag thiab silicon wafers hauv kev lag luam microelectronics;

7. Ua organosilicon: Organosilicon tebchaw muaj cov khoom ntawm ob qho tib si inorganic thiab organic cov ntaub ntawv, nrog rau cov khoom yooj yim xws li tsis tshua muaj qhov nro, me me viscosity-kub coefficient, siab compressibility, thiab siab gas permeability, thiab muaj cov khoom zoo heev xws li tsis kam mus rau siab thiab Tsis tshua muaj kub, hluav taws xob rwb thaiv tsev, thiab oxidation stability.

Lawv tau siv dav hauv aerospace, hluav taws xob thiab hluav taws xob, kev tsim kho, kev thauj mus los, tshuaj lom neeg, textile, zaub mov, kev lag luam teeb, kev kho mob thiab lwm yam lag luam. Hauv kev lag luam silicon kev lag luam saw, cov dej ntws yog cov khoom siv raw khoom tsim kev lag luam, feem ntau suav nrog silicon blocks, thermoelectricity, txo cov neeg ua haujlwm (xws li roj av coke, thee, charcoal, thiab lwm yam); cov downstream feem ntau yog cov khoom siv hluav taws xob, cov khoom siv tshuaj txhua hnub, photovoltaics, semiconductors, automotive manufacturing, vaj tse thiab lwm yam lag luam.

Cov txheej txheem ntawm kev lag luam silicon yog kwv yees li hauv qab no: Silica thiab txo tus neeg sawv cev yog hnyav rau hauv ib qho kev faib ua feem thiab tau txais kev ntxiv rau hauv lub qhov cub hluav taws xob submerged arc thiab rhuab mus rau saum 2000 degrees Celsius. Silicon dioxide yog txo los ntawm cov pa roj carbon dioxide los tsim cov kua silicon thiab carbon monoxide (CO) gas.

Cov pa roj CO khiav tawm ntawm cov khoom siv. Oxygen thiab cua sib xyaw roj yog nkag rau hauv qab ntawm silicon ladle kom tshem tawm lwm yam impurities xws li calcium thiab txhuas, thiab tom qab ntawd cov silicon ladle raug thauj mus rau hauv chav tsev casting los ntawm hluav taws xob 包车 mus rau hauv silicon ingots. Tom qab txias, cov silicon blocks tiav yog tau los ntawm crushing, grading, hnyav, ntim, thiab warehouses.

Ib tug loj npaum li cas ntawm hluav taws xob yog siv thaum lub sij hawm nws cov txheej txheem ntau lawm. Kev siv hluav taws xob rau smelting ib tuj ntawm kev lag luam silicon yog 11000-14000 kWh, thiab cov nqi hluav taws xob suav nrog feem ntau ntawm tag nrho cov nqi tsim khoom. Tuam Tshoj yog lub ntiaj teb tus tsim khoom loj tshaj plaws, cov neeg siv khoom, thiab xa tawm ntawm kev lag luam silicon.

Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm kev lag luam xws li lub zog tshiab thiab cov ntaub ntawv hluav taws xob, kev lag luam xav tau kev lag luam silicon tau txuas ntxiv mus. Txawm li cas los xij, tus nqi ntawm kev lag luam silicon fluctuates kuj sharply, uas ua rau qhov kev thov rau kev tswj tus nqi hloov pauv txaus ntshai los ntawm cov tuam txhab lag luam hauv cov saw hlau muaj zog.
