Khoom Description

Ferrosilicon yog ib qho tseem ceeb alloy ua los ntawm hlau thiab silicon. Cov hlau no muaj ntau daim ntawv thov kev lag luam, suav nrog nws siv ua deoxidizer, inoculant, thiab txo tus neeg sawv cev. Ferrosilicon kuj tseem siv rau hauv kev tsim cov hlau, cam khwb cia hlau, thiab lwm yam tsis-ferrous alloys. Nws qhov kev thov tas li hauv ntau daim ntawv thov kev lag luam tsis tuaj yeem overstated.

Cov tshuaj muaj pes tsawg leeg ntawm ferrosilicon txawv nyob ntawm seb nws xav siv. Feem ntau, nws muaj cov ntsiab lus silicon ntawm 15% mus rau 90%, thiab cov ntsiab lus hlau ntawm 75% mus rau 20%. Cov muaj pes tsawg leeg ntawm ferrosilicon hloov nws lub cev lub zog, xws li nws qhov ntom ntom, melting point, thiab thermal conductivity. Feem ntau, qhov siab dua cov ntsiab lus ntawm silicon, qhov siab dua qhov ceev thiab melting point ntawm cov hlau.

Ferrosilicon yog tsim los ntawm kev txo cov carbothermic ntawm silica. Nyob rau hauv cov txheej txheem no, silica thiab carbon yog rhuab nyob rau hauv ib tug hluav taws xob arc rauv, qhov uas lawv chemically reacts rau tsim ferrosilicon. Lub resulting alloy yog ces txias thiab crushed rau hauv ntau qhov ntau thiab tsawg, nyob ntawm seb nws npaj daim ntawv thov.

Qhov tseem ceeb ntawm kev siv ferrosilicon yog ua deoxidizer hauv steelmaking. Deoxidation yog cov txheej txheem tseem ceeb hauv kev tsim cov hlau, vim nws tshem tawm cov pa oxygen thiab lwm yam impurities los ntawm cov hlau molten. Ferrosilicon muaj txiaj ntsig zoo hauv cov txheej txheem no vim tias silicon muaj kev sib raug zoo rau cov pa oxygen, thiab ntxiv cov ferrosilicon rau hauv cov hlau molten tso cai rau kev tshem tawm cov impurities.

Ferrosilicon kuj tseem siv los ua ib qho inoculant. Inoculation yog tus txheej txheem ntawm kev qhia me me ntawm cov khoom tshwj xeeb lossis cov khoom sib xyaw rau hauv cov hlau molten los hloov nws cov microstructure. Ferrosilicon, thaum ntxiv rau cov hlau molten, hloov cov duab thiab qhov loj ntawm graphite hauv cov hlau, ua rau nws zoo dua rau cov hlau casting.

Thaum kawg, ferrosilicon kuj tseem siv los ua tus neeg sawv cev txo qis. Hauv metallurgy, tus neeg sawv cev txo qis yog ib yam khoom uas txo lwm yam khoom thaum ob qho tib si sib xyaw ua ke. Qhov sib ntxiv ntawm ferrosilicon rau cov hlau hauv qhov chaw txo qis tuaj yeem txo cov hlau cov ntsiab lus oxide, ua rau cov hlau ntau dua thiab yooj yim rau kev ua haujlwm nrog.

Hauv kev xaus, ferrosilicon yog ntau yam alloy nrog ntau hom kev siv hauv ntau yam lag luam. Nws cov tshuaj muaj pes tsawg leeg sib txawv nyob ntawm seb nws xav siv, thiab nws cov txheej txheem tsim muaj kev txo qis carbothermic ntawm silica. Nws txoj kev siv tseem ceeb yog ua deoxidizer, tab sis nws kuj yog siv los ua ib qho inoculant thiab txo tus neeg sawv cev. Qhov kev thov rau ferrosilicon tseem siab, thiab nws qhov tseem ceeb hauv kev tsim kho thiab kev tsim khoom lag luam tsis tuaj yeem kwv yees.
