Silicon Slag yog cov khoom lag luam los ntawm kev tsim cov khoom siv siab purity silicon xws li silicon hlau. Nws feem ntau yog ib qho seem uas tsim tawm hauv qhov kub kub thaum lub sij hawm smelting, tshwj xeeb tshaj yog thaum silicon raug rho tawm los ntawm ore. Cov muaj pes tsawg leeg, cov khoom siv lub cev thiab cov khoom siv tshuaj lom neeg ntawm silicon slag tuaj yeem sib txawv nyob ntawm cov khoom siv raw los ntawm qhov nws tau muab los thiab cov txheej txheem smelting.
silicon slag lub ntsiab Cheebtsam
- Silicon dioxide (SiO₂): qhov no yog cov khoom tseem ceeb ntawm silicon slag, tshwj xeeb tshaj yog thaum lub sij hawm smelting txheej txheem, thaum silicon ore reacts nrog cov pa roj carbon los tsim silicon dioxide.
- Fe₂O₃(Fe₂O₃): Vim yog siv cov hlau ore hauv cov txheej txheem smelting, silica slag feem ntau muaj qee qhov nyiaj ntawm Fe₂O₃(Fe₂O₃).
- Aluminium oxide (Al₂O₃): Qee lub sij hawm silica slag kuj muaj me me ntawm aluminium compounds, tshwj xeeb tshaj yog thaum aluminium ntxiv los ua cov khoom sib xyaw.
- Calcium Oxide (CaO) thiab Magnesium Oxide (MgO): Cov khoom no yog los ntawm cov fluxes siv hauv cov txheej txheem smelting thiab impurities hauv cov ore.
silicon slag tseem ceeb hom
1. High-Silicon Slag:
- Cov ntsiab lus silicon siab dua (feem ntau 40% mus rau 60%), feem ntau yog siv rau dephosphorization, desulfurization thiab kev kho cov acidity ntawm cov yaj hauv cov txheej txheem steel smelting.
- Siab silicon slag feem ntau yog siv hauv kev lag luam steel thiab aluminium alloy ntau lawm, ua tus neeg saib xyuas kev kho steel.
2. Tsawg-Silicon Slag:
- Nws muaj cov ntsiab lus tsis tshua muaj silicon (feem ntau tsawg dua 40%) thiab feem ntau yog siv hauv kev tsim iav, cov khoom siv refractory, thiab lwm yam.
silicon slag siv
Txawm hais tias silicon slag yog cov khoom lag luam ntawm cov txheej txheem smelting, nws muaj nqi rov qab siv dua, thiab nws cov ntawv thov tseem ceeb yog raws li hauv qab no:
1. steel smelting:
- Silica slag feem ntau yog siv los ua flux, desulfurizer thiab dephosphorizer hauv cov txheej txheem steelmaking los pab txhim kho cov hlau zoo thiab txo cov impurities.
2. Kev tsim cov cement:
- Cov ntsiab lus silica hauv silica slag tuaj yeem siv los hloov qee cov khoom siv cement, txo cov nqi tsim khoom thiab txhim kho kev ua haujlwm ntawm cov cement.
3. Kev tsim vaj tsev thiab kev tsim kho:
- Silica dregs tuaj yeem siv los ua cov khoom siv hauv tsev, tshwj xeeb tshaj yog sib sau ua ke hauv kev tsim kho txoj kev, txhawm rau txhim kho lub zog ntawm cov ntaub ntawv.
4. Kev tsim cov alloys thiab cov khoom siv refractory:
- Cov ntsiab lus siab ntawm silicon ntawm silica slag tuaj yeem siv los ua qee yam alloys, tshwj xeeb tshaj yog aluminium-silicon alloys. Nws kuj tseem siv rau hauv kev tsim cov cib refractory thiab lwm yam khoom siv kub-resistant.
5. Kev siv Agricultural:
- Silica slag qee zaum siv los ua cov av txias. Nws tuaj yeem txhim kho cov av pH, txhim kho cov qauv hauv av, thiab muab qee cov kab ke los txhawb kev loj hlob ntawm cov nroj tsuag.
6. Kev lag luam iav thiab ceramic:
- Cov khoom siv silica ntawm silica slag tuaj yeem siv los ua cov khoom siv hauv iav tsim los pab txhim kho cov cua sov thiab cov khoom siv ntawm iav.
silicon slag ib puag ncig thiab kev lag luam tseem ceeb
- Kev Tiv Thaiv Ib puag ncig: Kev rov ua dua silicon slag tuaj yeem txo cov khoom pov tseg thiab kev ua qias tuaj ib puag ncig. Nws pab txo qis ore mining thiab xav tau cov peev txheej ntuj.
- Cov txiaj ntsig kev lag luam: Los ntawm kev rov siv cov silica slag ua cov khoom siv raw, nws tuaj yeem txo cov nqi tsim khoom thiab tsim cov txiaj ntsig kev lag luam, nrog rau kev txhim kho kev siv cov khoom lag luam los ntawm cov khoom lag luam.
