High-carbon silicon yog ferrosilicon alloy nrog cov ntsiab lus siab carbon, feem ntau muaj hlau, silicon thiab carbon. Nws yog dav siv nyob rau hauv steelmaking thiab foundry industries, thiab tshwj xeeb tshaj yog tseem ceeb raws li ib tug txo thiab alloying tus neeg saib xyuas.
Lub cev thiab tshuaj muaj zog
- Cov khoom xyaw: Cov khoom tseem ceeb ntawm cov pa roj carbon ntau yog silicon (Si), uas feem ntau yog nyob ib ncig ntawm 60-70%, nrog cov ntsiab lus ntau dua ntawm cov pa roj carbon (C), feem ntau ntawm 6-8%, thiab cov seem yog hlau thiab lwm yam kab kawm.
- Cov tsos mob: Feem ntau lumpy los yog granular, grey los yog dub nyob rau hauv cov xim.
- Ceev: txog 3.2-3.5 g/cm³.
- Melting point: Lub melting point ntawm high carbon silicon yog hais txog 1350-1450 degree, uas txo qis nrog nce cov ntsiab lus carbon.
High carbon Silicon Applications
1. Steel ua kev lag luam
- Deoxidiser: High carbon silicon feem ntau yog siv los ua deoxidiser hauv cov txheej txheem steel, uas tuaj yeem tshem tawm cov pa tawm ntawm cov hlau, txo cov pa oxygen hauv cov hlau thiab txhim kho qhov zoo thiab purity ntawm cov hlau.
- Carbon Enhancer: Vim nws cov ntsiab lus carbon siab, High Carbon Silicon kuj tuaj yeem siv los ua cov pa roj carbon monoxide los tswj cov ntsiab lus ntawm cov hlau thiab txhim kho lub zog thiab hardness ntawm cov hlau.
2. KEV UA HAUJ LWM
- Inoculant: High-carbon silicon yog siv los ua inoculant nyob rau hauv cov txheej txheem casting, uas yuav pab txhim kho lub koom haum qauv ntawm cam khwb cia hlau, tiv thaiv tsis xws luag xws li shrinkage qhov thiab shrinkage loosening los ntawm tshwm nyob rau hauv lub castings, thiab txhim khu lub mechanical zog ntawm lub castings.
- Txo tus neeg sawv cev: Hauv cov txheej txheem smelting, cov pa roj carbon ntau tuaj yeem siv los ua tus neeg saib xyuas kom txo tau cov pa oxygen hauv cov hlau oxides thiab ua kom cov hlau tawm los.
3. Kev lag luam metallurgical
- Alloying tus neeg sawv cev: High-carbon silicon yog siv los ua alloying additive nyob rau hauv metallurgical kev lag luam, uas yuav tswj tau cov alloy muaj pes tsawg leeg thiab txhim kho cov hnav tsis kam, corrosion kuj thiab toughness ntawm cov ntaub ntawv.
Kev npaj siab carbon silicon
High-carbon silicon feem ntau yog tsim los ntawm hluav taws xob rauv smelting. Cov khoom siv tseem ceeb muaj xws li silica, coke lossis thee. Los ntawm kev kub kub smelting, silica hauv silica yog txo los tsim silicon, thiab cov pa roj carbon hauv coke koom nrog cov tshuaj tiv thaiv raws li tus neeg sawv cev txo, thaum kawg tsim cov ferrosilicon alloys nrog cov ntsiab lus siab carbon.
