Silicon Briquette yog ib hom khoom kheej kheej nrog silicon ua cov khoom tseem ceeb, feem ntau yog ua los ntawm ferrosilicon lossis silicon hlau los ntawm cov txheej txheem ntawm crushing, granulating thiab sintering. Silicon balls yog siv dav hauv kev lag luam metallurgical, tshwj xeeb tshaj yog nyob rau hauv steelmaking thiab casting li deoxidizers, inoculants thiab alloy additives. Raws li cov pob silicon muaj lub cev zoo thiab tshuaj lom neeg, lawv tau siv dav hauv kev lag luam niaj hnub, feem ntau pab txhim kho kev tsim khoom thiab cov khoom zoo.
silicon briquette lub ntsiab muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm cov pob silicon feem ntau suav nrog:
- Silicon (Si): cov ntsiab lus feem ntau yog li ntawm 40% mus rau 95%, thiab cov ntsiab lus silicon yuav txawv nyob ntawm daim ntawv thov.
- Hlau (Fe): cov ntsiab lus hlau hauv cov pob ferrosilicon siab, feem ntau yog siv los ua deoxidizer hauv steelmaking.
- Aluminium (Al) thiab Calcium (Ca): Qee qhov silica spheres kuj muaj cov khoom me me ntawm txhuas thiab calcium, muaj qhov uas pab ua kom zoo dua cov khoom siv hlau.
silicon briquette cov khoom tseem ceeb
1. Deoxygenation:
- Silicon muaj nyob rau hauv lub pob silicon tuaj yeem ua ke nrog cov pa oxygen hauv cov kua hlau los ua silica, yog li ua si cov nyhuv deoxidizing. Lub peev xwm deoxidizing ntawm silicon pob muaj zog, uas tuaj yeem txo cov ntsiab lus oxygen hauv cov hlau thiab tiv thaiv kev tsim cov porosity thiab suav nrog.
2. Kev yug me nyuam:
- Hauv kev tsim cov hlau cam khwb cia, cov pob silicon kuj tuaj yeem siv los ua cov inoculant. Cov inoculant tuaj yeem ua rau graphite crystallization hauv cam khwb cia hlau, yog li ua kom lub zog thiab tawv tawv ntawm cov hlau cam khwb cia thiab txhim kho cov khoom siv ntawm cov hlau cam khwb cia.
3. Alloying nyhuv:
- Silicon muaj nyob rau hauv silicon pob tuaj yeem txhim kho cov khoom sib xyaw ntawm cov hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hlau alloy thiab cov cuab yeej hlau, silicon yog ib qho tseem ceeb ntawm cov hlau alloying tuaj yeem txhim kho lub zog tensile, hardness thiab corrosion kuj ntawm hlau.
4. Kub kub tsis kam thiab hnav tsis kam:
- Silicon balls muaj qhov kub thiab txias tsis kam thiab hnav tsis kam, tshwj xeeb tshaj yog nyob rau hauv kub smelting thiab casting txheej txheem, nws muaj peev xwm tswj tau zoo stability thiab tiv thaiv hnav.
### Cov ntawv thov tseem ceeb:
Daim ntawv thov ntawm silicon briquette
1. Steelmaking:
- Silicon balls yog siv los ua deoxidizer, reacting nrog oxygen los tsim silica slag hauv cov txheej txheem steelmaking, txo cov pa oxygen hauv cov hlau thiab tiv thaiv qhov tsis xws luag xws li porosity hauv cov hlau. Tsis tas li ntawd, cov pob silicon kuj tuaj yeem siv los ua cov khoom siv hlau los kho cov tshuaj lom neeg ntawm cov hlau thiab txhim kho nws lub cev.
2. Casting:
- Hauv kev tsim cov hlau cam khwb cia, cov pob silicon feem ntau yog siv los ua cov inoculant, uas tuaj yeem kho cov graphite hauv cam khwb cia hlau, txhim kho qhov zoo ntawm castings, thiab txhim kho cov khoom siv ntawm cov cam khwb cia hlau xws li compressive zog thiab toughness.
3. Kev lag luam metallurgical:
- Silicon spheres yog dav siv nyob rau hauv lwm yam metallurgical txheej txheem, xws li smelting ntawm non-ferrous hlau, silicon spheres pab txhim kho cov tshuaj muaj pes tsawg leeg thiab melting zog ntawm cov ntaub ntawv hlau.
4. Hnub ci thiab semiconductor kev lag luam:
- High purity silicon npas yog siv nyob rau hauv zus tau tej cov polysilicon, uas nyob rau hauv lem yog siv nyob rau hauv kev tsim cov hnub ci vaj huam sib luag thiab nyob rau hauv lub semiconductor kev lag luam. High purity silicon cov ntaub ntawv yog ib qho tseem ceeb raw khoom rau kev lag luam electronics.
