1. Daim ntawv thov ntawm Ferrosilicon hauv Steelmaking Industry
1.1 Deoxidizer
Ferro Silicon (FeSi) yog ib qho uas feem ntau siv deoxidiser nyob rau hauv cov txheej txheem steelmaking, raws li nws reacts nrog oxygen nyob rau hauv cov hlau los tsim Silicon Dioxide (SiO₂), uas zoo txo cov pa oxygen hauv cov hlau. Cov txheej txheem no txhim kho qhov zoo ntawm cov hlau thiab txhim kho toughness thiab ductility, uas yog tshwj xeeb tshaj yog haum rau deoxidisation yuav tsum tau nruam casting molten steel. Tsis tas li ntawd, ferrosilicon tuaj yeem desulphurise thiab ntxiv purify cov hlau.
1.2 Alloying tus neeg sawv cev
Ntxiv ferrosilicon tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau. Hauv smelting ntau hom hlau, ferrosilicon ua tus neeg sawv cev alloying yog siv raws li hauv qab no:
Cov qauv hlau (muaj 0.40%-1}.75% silicon): txhawm rau txhim kho lub zog thiab tawv.
Cov cuab yeej steels (0.30-1.8 feem pua silicon): txhawm rau ua kom tawv tawv thiab hnav tsis kam.
Spring steels (0.40%-2.8% silicon): txhim kho elasticity thiab qaug zog tiv thaiv.
Silicon steel (muaj 2.81%-4.8% silicon): Txhim kho cov hlau nplaum conductivity
1.3 Cov khoom siv cua sov
Ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov los ntawm kev kub hnyiab, uas yog siv rau kev tsim cov cua sov ntawm ingot cap los txhim kho qhov zoo thiab rov qab tus nqi ntawm ingot.
2 Daim ntawv thov ntawm ferrosilicon hauv hlau casting kev lag luam
2.1 Tus neeg sawv cev yug me nyuam
Txhawb graphite nag lossis daus: Silicon hauv ferrosilicon txhawb kev tsim thiab nag lossis daus ntawm graphite hauv cam khwb cia hlau, yog li txhim kho cov khoom siv kho tshuab thiab kev co kuj ntawm cam khwb cia hlau.
Kev txhim kho ntawm lub koom haum cam khwb cia hlau: Los ntawm kev tswj cov morphology thiab kev faib tawm ntawm graphite, ferrosilicon txhim kho cov khoom siv dag zog thiab kev ua haujlwm ntev ntawm cov hlau cam khwb cia thiab txo cov kev ntxhov siab sab hauv thiab qhov tsis xws luag hauv castings.
2.2 Tus neeg sawv cev ductile
Ductile hlau muaj cov khoom siv kho tshuab zoo heev, nyob ze lossis ntawm qib hlau. Lub luag haujlwm ntawm ferrosilicon ua tus neeg sawv cev spheroidising hauv kev tsim cov hlau hlau muaj xws li:
Txhawb nqa spheroidization: Cov silicon hauv ferrosilicon tuaj yeem pab hloov cov carbides hauv cov hlau rau hauv cov graphite kheej kheej, txhim kho cov tawv tawv thiab lub zog ntawm cov hlau ductile.
Txhim kho qhov zoo ntawm casting: Los ntawm kev txhawb nqa spheroidisation, ferrosilicon txo cov brittleness hauv castings thiab txhim kho lawv cov kev cuam tshuam thiab qaug zog.
3. cov ntsiab lus
Ferrosilicon muaj ntau yam kev siv nyob rau hauv steelmaking thiab hlau casting industries, thiab nws lub luag hauj lwm raws li ib tug deoxidiser, alloying neeg sawv cev, inoculant thiab spheroidising tus neeg saib xyuas yog irreplaceable. Los ntawm kev siv cov ferrosilicon zoo, qhov zoo thiab kev ua haujlwm ntawm cov hlau thiab cam khwb cia hlau tuaj yeem txhim kho tau zoo, thaum txo cov nqi tsim khoom thiab txhim kho cov txheej txheem ntau lawm. Lub versatility thiab high efficiency ntawm ferrosilicon ua rau nws tuav ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub niaj hnub metallurgical kev lag luam thiab txhawb txoj kev loj hlob thiab kev vam meej ntawm cov hlau thiab cam khwb cia hlau industries.
Cov saum toj no yog cov lus qhia ntxaws ntxaws rau daim ntawv thov ntawm ferrosilicon hauv steelmaking thiab hlau casting kev lag luam thiab nws qhov tseem ceeb. Vam tias, lawv yuav muab cov ntaub ntawv tseem ceeb rau koj kom nkag siab tob txog lub luag haujlwm thiab kev ua haujlwm ntawm ferrosilicon hauv kev lag luam.
