Kev faib tawm ntawmsilicon hlaurau hauv "oxygened" thiab "non-oxygen" feem ntau yog raws li nws cov tshuaj tiv thaiv muaj peev xwm oxygen thiab nws cov kev ua tau zoo hauv kev siv tswv yim. Ob qhov kev faib tawm no qhia txog cov yam ntxwv sib txawv ntawm silicon hlau hauv metallurgy thiab alloy ntau lawm. Nov yog qhov sib txawv ntawm ob hom thiab lawv txoj haujlwm:
oxygened silicon
oxygened silicon (tseem hu ua "silicon oxide" lossis "deoxidized silicon") yog hais txog cov hlau silicon uas tuaj yeem ua haujlwm zoo nrog oxygen thaum lub sijhawm tsim khoom kom tshem tawm cov pa impurities hauv cov hlau yaj. Hom silicon no muaj peev xwm deoxidizing muaj zog.
Nta
High purity: feem ntau purity siab, tsis tshua muaj oxygen cov ntsiab lus, haum rau siv raws li ib tug deoxidizer.
Daim ntawv thov dav: siv nyob rau hauv aluminium smelting thiab aluminium alloy ntau lawm los pab tshem tawm cov pa tawm ntawm cov yaj thiab txhim kho qhov zoo ntawm aluminium alloys.
Muaj nuj nqi: Hauv aluminium alloy ntau lawm, oxygened silicon tuaj yeem ua ke nrog cov pa oxygen hauv cov kua txhuas los ua silicates, yog li tshem tawm oxygen, tiv thaiv aluminium oxidation, thiab txhim kho txhuas zoo thiab lub zog.
Hom kev siv
Aluminium alloy ntau lawm: txhim kho qhov zoo ntawm txhuas thiab txhim kho lub cev thiab tshuaj lom neeg ntawm aluminium alloys.
Steelmaking: Raws li deoxidizer, nws tshem tawm cov pa oxygen los ntawm cov hlau molten thiab txhim kho kev ua haujlwm ntawm cov hlau.
Tsis-oxygenated silicon
Non-oxygenated silicon (tseem hu ua "non-deoxidized silicon" lossis "low-oxygen silicon") yog hais txog silicon uas muaj peev xwm oxidation tsis muaj zog thaum lub sijhawm tsim khoom, thiab nws cov nyhuv tshem tawm oxygen tsis zoo li oxygenated silicon. Hom silicon no feem ntau muaj cov pa oxygen ntau dua.
Nta
Tsawg purity: siab oxygen cov ntsiab lus thiab tsis muaj zog deoxidation muaj peev xwm.
Kev txwv tsis pub siv: feem ntau yog siv rau hauv kev tsim cov aluminium alloys thiab lwm yam alloys uas tsis tshua muaj deoxidation.
Muaj nuj nqi: Feem ntau yog siv los txhim kho lwm yam khoom ntawm alloys, xws li fluidity thiab castability, tab sis tsis zoo li oxygenated silicon hauv deoxidation nyhuv.
Hom kev siv
Casting alloys: Txhim kho cov fluidity thiab casting zog ntawm alloys.
Alloy additives: Siv nyob rau hauv zus tau tej cov txhuas alloys thiab lwm yam metallurgical khoom uas tsis muaj purity yuav tsum.
Kev faib tawm ntawm "oxygenated" thiab "non-oxygenated" silicon hlau feem ntau qhia txog qhov txawv ntawm nws lub peev xwm deoxidation. Oxygenated silicon muaj peev xwm deoxidation ntau dua thiab tsim nyog rau cov ntawv thov uas muaj cov pa oxygen tshem tawm siab, xws li deoxidation hauv aluminium alloy ntau lawm. Cov pa oxygen tsis muaj silicon yog tsim rau cov ntawv thov uas tsis tas yuav tsum muaj kev xav tau siab deoxidation, thiab nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho lwm yam khoom ntawm cov hlau. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv txoj cai ntawm cov xim hlau silicon raws li cov kev xav tau ntau lawm thiab kev siv.
