Kev piav qhia
Silicon carbon alloy, tseem hu ua ferro silicon carbon (FeSiC), yog ib hom ferroalloy siv hauv metallurgical steel ua. Nws yog tsim los ntawm silicon, carbon, thiab hlau, nrog silicon cov ntsiab lus xws li 15 feem pua rau 9 0 feem pua thiab cov ntsiab lus carbon li ntawm 0.1 feem pua rau 6 feem pua.
Qhov sib ntxiv ntawm silicon carbon alloy rau steelmaking muaj ntau yam txiaj ntsig, suav nrog:
▼Deoxidation: Silicon reacts nrog oxygen los tsim silicon dioxide, uas yog ib qho chaw ruaj khov uas tuaj yeem tshem tau yooj yim ntawm cov hlau molten. Cov txheej txheem no pab tshem tawm impurities thiab txhim kho tag nrho cov hlau zoo.
▼ Desulfurization: Silicon kuj reacts nrog sulfur los tsim cov tebchaw ruaj khov uas tuaj yeem raug tshem tawm ntawm cov hlau molten. Qhov no yuav pab txo qis cov ntsiab lus sulfur hauv cov hlau, uas tuaj yeem txhim kho nws cov khoom siv kho tshuab.
▼ Carbon ntxiv: Cov ntsiab lus carbon ntawm cov hlau tuaj yeem hloov kho kom muab cov qib siab ntawm cov pa roj carbon hauv cov khoom siv hlau kawg. Qhov no yog qhov tseem ceeb vim tias carbon yog qhov tseem ceeb hauv kev txiav txim siab lub zog thiab hardness ntawm cov hlau.
▼ Nqi-zoo: Kev siv cov silicon carbon alloy tuaj yeem raug nqi ntau dua li siv lwm hom ferroalloys vim nws muab ntau yam txiaj ntsig hauv ib qho ntxiv.
