Raws li ib qho tseem ceeb muaj raw khoom siv,Silicon HlauUa lub luag haujlwm tseem ceeb hauv metallurgy, kev lag luam chemical, khoom siv hluav taws xob thiab lwm daim teb. Ntawm lawv,Silicon Hlau 553thiabSilicon Hlau 521yog ob lub qhab nia siv dav dav, uas muaj ob qho zoo sib xws thiab pom tseeb sib txawv.
1. Qhov zoo sib xws ntawm Silicon hlau 553 thiab silicon hlau 521
1.1. Cov ntsiab lus txhais thiab siv hauv paus
Silicon 553 thiab silicon 521 yog ob qho tib siMetallurgical Qib Silicon, mas muaj xws li silicon thiab impurity sis xws li hlau, txhuas, thiab yog kho kom zoo nkauj ntawm cov xuab zeb xuab zeb thiab coke nyob rau hauv ib submerged arc rauv. Ob qho tib si yog cov ntaub ntawv muaj kev lag luam tseem ceeb, siv dav hauv cov khoom siv hlau, nrhiav cov khoom lag luam sillicing, muab cov khoom lag luam silicon sib txuas, muab cov khoom silicon sib txuas thiab txhim kho cov khoom ntxiv thiab txhim kho cov khoom siv.
1.2. Cov txheej txheem ntau lawm
Cov txheej txheem ntau lawm ntawm ob yog yeej zoo ib yam, thiab ob leeg yuav tsum tau cov khoom siv raw, sminting, ua kom zoo, casting thiab lwm qhov txuas. Nyob rau hauv raw khoom npaj theem, siab zoo quartz xuab zeb thiab coke siv, thiab lawv qhov loj thiab huv nruj me ntsis tswj tau; Cov txheej txheem smelting yog nqa tawm hauv lub submerged arc rauv, thiab silicon caij nyob rau hauv cov ntaub ntawv raw yog txo los ntawm kub; Lub chaw ua kom huv yog kom tshem tawm cov impurities thiab txhim kho txoj kev coj dawb huv ntawm silicon; Thaum kawg, cov hlau tiav hlau silicon yog tau los ntawm casting.
2. Qhov sib txawv ntawm cov hlau silicon 553 thiab hlau silicon 521
2.1. Tshuaj lom neeg muaj pes tsawg leeg
| Hom | Zaum fe | Al | Ca |
| Silicon Hlau 553 | Tsawg dua los yog sib npaug rau 0. 5% | Tsawg dua los yog sib npaug rau 0. 5% | Tsawg dua los yog sib npaug rau 0. 3% |
| Silicon Hlau 521 | Tsawg dua los yog sib npaug rau 0. 2% | Tsawg dua los yog sib npaug rau 0. 2% | Tsawg dua los yog sib npaug rau 0. 1% |
2.2. Kev ua yeeb yam ntawm lub cev
Vim muaj qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg, ob qho tseem muaj qhov sib txawv ntawm cov khoom siv lub cev. Hlau silicon 521 muaj siab huv, thiab nws lub hardness, ntom ntom thiab lwm yam hluav taws xob thiab cov khoom siv hluav taws xob zoo li cov khoom siv hluav taws xob thiab thermal conductivity tseem zoo dua; Hauv kev sib piv, hlau silicon 553 yog me ntsis qis dua nyob rau hauv lub ruaj khov thiab kev ua tau zoo ntawm lub cev muaj zog vim nws cov ntsiab lus impurity. Piv txwv li, hauv kev lag luam hluav taws xob, uas yuav tsum muaj cov khoom siv silicon raw, thiab hlau silicon 521 tuaj yeem ua tau zoo dua nws cov kev xav tau; Thaum hlau Silicon 553 kuj tuaj yeem ua tau nws txoj kev ua tau zoo hauv qee qhov kev thov nrog cov kev xav tau tsawg.
2.3. Daim Ntawv Thov Kev Ua Yeeb Yam
Silicon hlau 553: Vim hais tias ntawm nws cov ntsiab lus impurity thiab tus nqi qis, nws feem ntau siv nyob rau hauv cov teb uas cov ntshav siab uas tsis muaj siab. Hauv steel smeel, nws tuaj yeem siv ua adeoxidizerthiabAlloy AdditiveTxhawm rau kom txo cov pa oxygen hauv cov hlau molten thiab txhim kho lub zog thiab tawv ntawm cov hlau; Nyob rau hauv lub foundry kev lag luam, silicon 553 tuaj yeem txhim kho cov tshuaj thiab cov neeg kho tshuab ntawm cov hlau cam khwb cia ntawm cov hlau thiab cov hlau cam, thiab txo cov cam khwb cia; Tsis tas li ntawd, hauv kev tsim tawm qee qhov nqi-rhiab dog dig Organosilicon tebchaw, silicon hlau 553 kuj yog feem ntau siv los ua cov khoom siv raw.
Silicon hlau 521: Nrog nws cov yam ntxwv siab dawb huv, nws yog tsuas yog siv nyob rau hauv high-end liaj teb nrog siab silicon purity tseev kom muaj. Hauv kev lag luam silicone, nws yog siv los tsim cov khoom zoo silicone monomers thiab polymers, uas tau siv dav hauv cov khoom siv hluav taws xob, kho mob, aerospace thiab lwm yam lag luam; Nyob rau hauv polysilicon ntau lawm, silicon 521 yog ib qho ntawm cov ntaub ntawv tseem ceeb. Tom qab kev ua kom huv ntxiv, nws tuaj yeem siv los ua cov khoom siv hnub ci thiab cov khoom siv ua kom cov khoom siv hluav taws xob tshiab thiab hluav taws xob kev lag luam.
2.4. Kev Lag Luam Nqe Qhov Sib Txawv
Cuam tshuam los ntawm kev coj dawb huv thiab cov nqi ntau lawm, tus nqi lag luam ntawm 521 qib silicon hlau feem ntau yog siab dua li ntawm 553 qib silicon hlau. Raws li cov hlau tsheb 521 muaj cov khoom siv silicon 521 muaj cov khoom siv ua kom muaj zog ntau dua thaum muaj ntau yam ntxiv, uas ua rau muaj kev nce qib ntau, uas yog xav txog ntawm tus nqi. Piv txwv li, raws li qhov xwm txheej ntawm kev ua lag luam ruaj khov thiab thov tau, tus nqi ntawm cov khoom lag luam silicon 521} {%. Kev lag luam yuav tsum tau ua tib zoo mloog kom ze rau kev ua lag luam thaum mus yuav khoom.
Txawm hais tias ob qho tib si mellurgical Silicon 553 thiab Metallurgical Silicon 521 yog cov khoom siv tshuaj lom neeg, cov khoom siv lub cev, daim ntawv thov cov nqi lag luam thiab cov nqi lag luam. Thaum xaiv siv lawv, kev lag luam yuav tsum muaj kev nkag siab zoo xws li cov khoom lag luam sib txawv ntawm cov khoom siv sib txawv thiab ua tiav qhov teeb meem yeej hauv kev lag luam thiab cov khoom lag luam zoo.
