Kev Paub Txog Ferrosilicon

(1) Ferrosilicon yog siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steel. Txhawm rau kom tau txais cov hlau nrog cov tshuaj tsim nyog thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau theem kawg ntawm cov hlau smelting. Ferrosilicon yog lub zog deoxidizer rau steelmaking vim muaj zog tshuaj lom neeg ntawm silicon thiab oxygen thiab siv rau nag lossis daus thiab diffusion deoxidation. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem ua rau nws lub zog, hardness, thiab elasticity. Yog li ntawd, ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying hauv smelting ntawm cov qauv hlau (muaj 0.40-1.75% silicon), cov cuab yeej hlau (muaj 0.30-1 .8% Si), caij nplooj ntoos hlav steel (muaj 0.40-2.8% Si) thiab silicon steel rau transformers (muaj 2.{11}}.8% Si).

Tsis tas li ntawd, nyob rau hauv kev lag luam steel, ferrosilicon hmoov feem ntau yog siv los ua cov khoom cua sov rau steel ingot caps los txhim kho qhov zoo thiab rov qab tus nqi ntawm cov hlau ingots los ntawm kev siv nws cov cuab yeej los ntawm kev tsim cov cua kub ntau thaum kub kub.

(2) Ferrosilicon yog siv los ua inoculant thiab spheroidizing tus neeg sawv cev hauv kev lag luam hlau. Cam khwb cia hlau yog cov khoom siv hlau tseem ceeb hauv kev lag luam niaj hnub no. Nws yog pheej yig dua li hlau, yooj yim rau yaj thiab smelt, muaj zoo heev casting zog thiab zoo dua seismic tsis kam tshaj hlau. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov khoom siv hlau, nws cov khoom siv tshuab yog sib npaug los yog ze rau cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Yog li ntawd, ferrosilicon yog ib qho tseem ceeb inoculant (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev nyob rau hauv zus tau tej cov ductile hlau.
