Khoom Description
Hlau silicon 441 yog smelted nyob rau hauv lub submerged arc rauv los ntawm silica thiab carbonaceous txo tus neeg sawv cev. Nws cov khoom tseem ceeb yog silicon, uas suav txog li 26% ntawm qhov loj ntawm lub ntiaj teb crust. Nws yog ib qho tseem ceeb ntawm kev lag luam raw khoom. Lub "441" nyob rau hauv hlau silicon 441 sawv cev tias nws cov hlau, txhuas thiab calcium cov ntsiab lus yog 0.4%, 0.4% thiab 0.1% feem. Raws li cov ntsiab lus sib txawv ntawm hlau, txhuas thiab calcium hauv hlau silicon, hlau silicon kuj tuaj yeem muab faib ua ntau qib xws li 553, 411, 421, 3303, 3305, 2202, 2502, 1501 thiab 1101. Hlau silicon 441 yog grey thiab muaj xim hlau. Kev ntxhib los mos ntawm hlau silicon 441 yog tawv thiab nkig.
Kev lag luam tus nqi ntawm cov hlau silicon 441 yuav raug cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv thiab kev xav tau ntawm cov khoom siv raw, cov khoom purity, kev hloov pauv hauv kev xav tau ntawm kev lag luam thiab tsoomfwv cov cai. Raws li cov ntaub ntawv pej xeem, kev lag luam tus nqi ntawm cov hlau silicon 441 tau hloov pauv tsis ntev los no, tab sis tseem nyob ruaj khov tag nrho. Tam sim no, cov khoom siv ntawm cov hlau silicon 441 yog qhov ruaj khov, tab sis tag nrho cov khoom ntim ntawm qhov xav tau yog txwv, thiab kev ua lag luam nyob rau hauv kev tos-thiab-saib mus ob peb vas. Kev sib kis ntawm cov khoom siv thiab kev xav tau tsis muaj zog, thiab kev ua lag luam tsis muaj kev txhawb nqa zoo. Cov khoom siv ntxiv ntawm Silicon Metal 441 muaj xws li microsilicon hmoov (tseem hu ua silica fume, microsilica hmoov lossis silica fume), thiab lwm yam. Microsilicon hmoov yog dav siv hauv cov khoom siv refractory thiab kev lag luam pob zeb.
Hlau silicon 441 feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis muaj hlau hauv kev lag luam metallurgical. Thaum silicon ntxiv rau qee yam hlau uas tsis yog-ferrous, nws tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm lub hauv paus hlau, thiab qee zaum txhim kho cov casting thiab vuam zog ntawm lub hauv paus hlau. Tsis tas li ntawd, hlau silicon 441 kuj tseem siv tau los ua deoxidizer rau smelting tshwj xeeb steels thiab non-ferrous alloys. Hlau silicon 441 kuj tau siv dav hauv photovoltaics, silicones thiab lwm yam. Nrog rau kev nce hauv ntiaj teb kev thov rau lub zog tauj dua tshiab, daim ntawv thov ntawm cov hlau silicon 441 hauv kev lag luam photovoltaic txuas ntxiv nthuav dav. Tsis tas li ntawd, hlau silicon 441 kuj tseem siv rau hauv kev tsim cov khoom siv silicone xws li roj hmab silicone thiab silicone resin, uas tau siv dav hauv kev tsim kho, hluav taws xob thiab tsheb lag luam. Hauv cov ntsiab lus, hlau silicon 441 yog ib qho tseem ceeb ntawm cov khoom siv raw, uas yog siv dav hauv ntau lub teb xws li steelmaking thiab alloy manufacturing. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, kev lag luam xav tau rau hlau silicon 441 yuav tsum nthuav dav ntxiv.
