Dab tsi yog Cov Txheej Txheem Feem Ntau thiab Cov Qauv Hauv Tebchaws ntawm Ferrosilicon?
Ferrosilicon, hlau -silicon alloy smelted nyob rau hauv hluav taws xob furnaces siv coke, steel seem, thiab quartz (los yog silica) raws li raw cov ntaub ntawv, yog dav siv raws li ib tug deoxidizer nyob rau hauv lub steelmaking kev lag luam. Kev nkag siab txog nws cov kev faib tawm thiab cov qauv hauv tebchaws yog qhov tseem ceeb rau kev lag luam uas tso siab rau qhov zoo ib yam thiab siab - cov ntaub ntawv zoo. Hauv qab no, peb rhuav tshem cov ntsiab lus tseem ceeb ntawm ferrosilicon raws li tau hais los ntawm Suav teb cov qauv.
1. Kev faib tawm
Ferrosilicon tau muab faib ua plaub hom raws li kev tsim khoom thiab muaj pes tsawg leeg:
- Siab -Silicon Ferrosilicon (GG)
- Txheem Ferrosilicon (PG)
- Tsawg-Aluminium Ferrosilicon (DL)
- Siab -Purity Ferrosilicon (GC)
High-purity ferrosilicon, tshwj xeeb tshaj yog, yog tsim los ntawm cov txheej txheem kho kom zoo sab nraud kom txo qis cov ntsiab lus impurity.
2. Qib Qib Qib
Qib naming convention raws li ib tug meej qauv:
- Thawj ob tsab ntawv qhia txog hom ferrosilicon (piv txwv li, GG, PG, DL, GC).
- Qhov no yog ua raws li cov khoom code "FeSi."
- Tus lej tom ntej no sawv cev qis dua ntawm cov ntsiab lus silicon (piv txwv li, 97 qhia qhov tsawg kawg nkaus ntawm 97% silicon).
- Cov ntawv sau ntxiv qhia txog cov kev txwv sab saud ntawm cov impurities tseem ceeb (piv txwv li, "Al1.5" qhia cov ntsiab lus txhuas capped ntawm 1.5%).
- Rau siab -purity ferrosilicon, ib tsab ntawv kawg (A, B, lossis C) faib cov theem nrab impurity.
3. Chemical Composition Requirements
Ferrosilicon tau muab faib ua 40 qib thoob plaws plaub pawg, txhua tus muaj cov qauv tshuaj lom neeg nruj:
- Tshuaj muaj pes tsawg leeg ntawm siab -Silicon Ferrosilicon
