Ferrosilicon yog cov khoom siv ferro alloy, feem ntau yog tsim los ntawm silicon thiab hlau, nrog me me ntawm carbon, aluminium, calcium thiab lwm yam ntxiv. Cov ntsiab lus ntawm silicon ntawm ferrosilicon feem ntau yog nyob nruab nrab ntawm 40% thiab 75%, thiab cov ntsiab lus hlau feem ntau yog nruab nrab ntawm 25% thiab 60%. Cov ntsiab lus carbon ntawm ferrosilicon feem ntau tsis tshaj 2.0%, thiab cov ntsiab lus oxygen feem ntau tsis tshaj 2.5%. Nyob rau tib lub sijhawm, ib qho me me ntawm txhuas, calcium, magnesium thiab lwm yam khoom yuav raug ntxiv los txhim kho nws cov kev ua tau zoo.
Ntawd yog, 75A ferrosilicon hais txog75 ferrosilicon hlau, thiab 75B ferrosilicon hais txog72 ferrosilicon ua.
75 ferro silicon thiab 72 ferro silicon yog ob qhov sib txawv ntawm ferrosilicon. Qhov sib txawv tseem ceeb yog nyob rau hauv tus nqi ntawm silicon lawv muaj.
Cov ntsiab lus silicon ntawm ferrosilicon 75 yog nyob nruab nrab ntawm 74-80%. Nws yog ib qho nyuaj ferrosilicon 75 thiab feem ntau yog siv los ua deoxidizer hauv kev lag luam steelmaking. Cov ntsiab lus silicon ntawm ferrosilicon 72 yog nyob nruab nrab ntawm 72-80%. Nws yog ib qho mos ferrosilicon 75, uas tseem siv dav hauv cov nroj tsuag txhuas thiab tseem siv los ua deoxidizer hauv kev lag luam steelmaking.
Kev siv 75 ferrosilicon thiab 72 ferrosilicon yog raws li hauv qab no
Kev siv tseem ceeb ntawm 75 ferrosilicon yog cov deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steel, thiab ua tus neeg sawv cev inoculant thiab spheroidizing hauv kev lag luam cam khwb cia hlau.
Tshwj xeeb, 75 ferrosilicon tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten thiab txhim kho cov purity thiab zoo ntawm cov hlau. Nyob rau tib lub sijhawm, nws tseem tuaj yeem siv los ua cov khoom siv alloying ntxiv los txhim kho cov khoom ntawm cov hlau.
Tsis tas li ntawd, 75 ferrosilicon kuj tseem siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm
72 Ferrosilicon feem ntau yog siv los ua cov khoom siv alloying ntxiv thiab yog siv dav hauv cov hlau tsis tshua muaj hlau, lub caij nplooj ntoos hlav steel, cov kabmob hlau, cov hlau tsis muaj cua sov thiab hluav taws xob silicon steel. Nws kuj tseem siv tau los ua ib qho inoculant hauv kev tsim cov hlau ductile thiab malleable hlau.
