Taw qhia rau cov siab Silicon Carbon

Steelmaking:

Ua raws li lub haib deoxidizer, hloov ferrosilicon hauv qee cov kev siv .

Txhim kho cov kab hlau thiab txo cov txheej txheem slag .

CIA MARK NTAU LAWM:

Txhim kho graphitization thiab cov khoom siv mechanies .

Hloov kho cov ntsiab lus carbon cov ntsiab lus zoo .

Lwm Yam Siv:

Cov khoom siv raw rau silicon carbide (sic) synthesis .

Additive hauv brazing alloys thiab vuam cov ntaub ntawv .

Nqi-tsim nyog piv rau ib txwm deoxidizers .

High efficiency hauv carbon thiab silicon ntxiv .

Txo kev siv hluav taws xob hauv cov txheej txheem smelting .

Txuj Ci Ntau Lawm

Tsim nyob rau hauv submerged arc rauv taws los ntawm smelting quartz (sitio₂) thiab cov khoom siv carbon monoxide (E . {{{2}

High-carbon silicon txuas hniav txuas hniav ntawm Ferrosilicon thiab cov tshuaj ntxiv cov pa roj carbon monoxide, muab cov tshuaj cais roj carbon monoxide rau niaj hnub no

Cov Khoom Siv Hluav Taws Xob HighSon (Sic Alloy) yog cov khoom siv sib xyaw nrog cov khoom siv tshwj xeeb thiab tshuaj lom neeg, ua rau nws tsis tseem ceeb hauv cov ntawv siv metallengical.

A .}}}}}}} Cov Tshuaj Muaj Zog:

Silicon (si): 55-75% - muab cov txiaj ntsig deoxidation muaj zog thiab kev sib txuam zoo.

Cov pa roj carbon (c): 8-20% - Ua haujlwm ua tus neeg sawv cev carburizing {2 2}}

Trac impurities: hlau (fe), txhuas (al), calcium (CA), thiab lwm yam.

b . lub cev cov khoom:

Zog: Grey-Dub Lumps lossis Granules Nrog Nws Yog Tus Hlautaus Luster.

Melting taw tes: ~ 1300-1400℃(sib txawv nrog kev sib xyaw) .

Ntsej zog: ~ 2 .} 5-3.0 g / cm³.

Siab ruaj khov: tiv thaiv oxidation thaum lub sij hawm cia thiab thauj .

c . Cov zoo dua lwm txoj hauv kev:

Nqi-efficiency: pheej yig dua ferrosilicon thiab hluavtaws graphite.

Cov haujlwm dual: ib txhij muab cov khoom silicon thiab carbon .

Zog-Txuag: Lowers Smelting Kub hauv Steelmaking.
