Khoom Description

Ferrosilicon yog cov khoom siv dav siv hauv ntau daim ntawv thov sib txawv. Nws yog ib qho hlau uas ua los ntawm cov hlau thiab silicon, thiab nws muaj qee qhov tshwj xeeb ntawm lub cev uas ua rau nws muaj txiaj ntsig zoo rau ntau yam kev lag luam. Hauv tsab xov xwm no, peb yuav tshawb txog qee yam ntawm lub cev ntawm ferrosilicon thiab lawv siv li cas hauv kev siv sib txawv.

1. Ceev ceev

Ib qho tseem ceeb ntawm lub cev muaj zog ntawm ferrosilicon yog nws qhov ntom. Qhov ceev ntawm ferrosilicon txawv nyob ntawm seb muaj pes tsawg leeg ntawm cov khoom. Feem ntau, nws txawv ntawm 6.7 mus rau 7.15 grams ib cubic centimeter. Qhov ntom ntom no ua rau ferrosilicon cov khoom hnyav, uas muaj txiaj ntsig zoo hauv ntau daim ntawv thov kev lag luam, xws li hauv kev tsim cov khoom siv tsheb.

2. Melting point

Lwm yam khoom tseem ceeb ntawm lub cev ntawm ferrosilicon yog nws qhov siab melting point. Lub melting point ntawm ferrosilicon tuaj yeem nyob ntawm 1210 txog 1250 degrees Celsius, nyob ntawm seb muaj pes tsawg leeg ntawm cov khoom. Qhov siab melting point no ua rau ferrosilicon muaj txiaj ntsig zoo hauv kev siv kub kub, xws li hauv kev tsim cov hlau.

3. Hardness

Ferrosilicon yog cov khoom siv tawv vim muaj cov ntsiab lus siab ntawm silicon. Lub hardness ntawm ferrosilicon txawv nyob ntawm seb tus nqi ntawm silicon tam sim no nyob rau hauv lub alloy. Feem ntau, nws muaj qhov nyuaj ntawm 370 thiab 530 ntawm Vickers hardness nplai. Qhov hardness no ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov kev lag luam, xws li hauv kev tsim cov abrasives.

4. Cov khoom sib nqus

Ferrosilicon yog ib yam khoom ferromagnetic, uas txhais tau hais tias nws yog attracted rau ib tug hlau nplaum. Cov khoom sib nqus ntawm ferrosilicon sib txawv nyob ntawm seb muaj pes tsawg leeg ntawm cov khoom. Feem ntau, ferrosilicon nrog cov ntsiab lus hlau siab yog sib nqus ntau dua ferrosilicon nrog cov ntsiab lus hlau tsawg. Cov cuab yeej sib nqus no ua rau ferrosilicon muaj txiaj ntsig hauv ntau daim ntawv thov, xws li hauv kev tsim cov khoom sib nqus.

5. Corrosion kuj

Ferrosilicon tiv taus corrosion vim muaj cov ntsiab lus siab ntawm silicon. Qhov no ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov uas tiv thaiv corrosion yog qhov tseem ceeb, xws li hauv kev tsim cov hlau tsis muaj steel.

Hauv kev xaus, ferrosilicon yog ntau yam khoom siv uas muaj ntau yam khoom siv lub cev uas ua rau nws muaj txiaj ntsig zoo rau ntau yam kev lag luam. Los ntawm nws qhov siab ceev thiab melting point rau nws hardness thiab magnetic zog, ferrosilicon yog ib qho tseem ceeb cov ntaub ntawv uas plays lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam kev lag luam. Txawm hais tias nws yog siv hauv kev tsim cov hlau los yog hauv kev tsim cov khoom sib nqus, ferrosilicon yog cov khoom siv tseem ceeb rau kev lag luam niaj hnub no.
