Taw qhia thiab daim ntawv thov CAS:8049-17-0|Ferric silicon
1. Ib qho hlau alloy uas muaj cov silicon thiab hlau nrog cov ntsiab lus silicon nyob rau hauv thaj tsam ntawm 8.0% mus rau 95.0%. Ferrosilicon muaj txog 50% silicon feem ntau yog siv los ntxiv silicon thaum melting hlau hauv cupola furnaces; ferrosilicon muaj li 75% silicon feem ntau yog siv. Nws yog siv los ua inoculant thiab inking tus neeg sawv cev rau cam khwb cia hlau, deoxidizer thiab cov khoom siv silicon-nce rau steelmaking; Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, thiab nws yog ib qho yooj yim rau synthesize silica, yog li ferrosilicon feem ntau yog siv los ua deoxidizer hauv steelmaking. (Ntxhis deoxidation thiab diffusion deoxidation). Nyob rau tib lub sijhawm, ferrosilicon kuj tseem siv tau los ua cov khoom siv alloying ntxiv thiab tau dav siv 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. Ferrosilicon feem ntau yog siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab kev lag luam tshuaj.
2. Tsuas yog cov hlau boiled thiab semi-tua steel, cov ntsiab lus silicon nyob rau hauv steel yuav tsum tsis txhob tsawg tshaj li 0.10%. Silicon tsis tsim cov carbide hauv cov hlau, tab sis muaj nyob rau hauv cov tshuaj tov hauv ferrite thiab austenite. Silicon muaj qhov cuam tshuam zoo rau kev txhim kho lub zog ntawm cov khoom siv hauv cov hlau thiab kev ua haujlwm txias deformation hardening tus nqi, tab sis txo cov toughness thiab plasticity ntawm cov hlau; Nws muaj cov nyhuv nruab nrab ntawm cov hlau hardenability, tab sis nws tuaj yeem txhim kho tempering stability thiab oxidation tsis kam ntawm cov hlau, yog li silicon Hlau yog siv los ua tus neeg sawv cev alloying hauv kev lag luam steelmaking.
3. Ferrosilicon, uas muaj li ntawm 90% ntawm silicon, feem ntau yog siv los tsim cov hlau tsis tshua muaj hlau, thiab tseem siv los tsim cov khoom siv silicone thiab cov ntxhia silicic acid activators; crystalline silicon yog siv nyob rau hauv zus tau tej cov uas tsis yog-hlau-raws li alloys thiab high-purity alloys, thiab kuj yog siv nyob rau hauv lub electronics kev lag luam tseem ceeb raw cov ntaub ntawv. Silicon kuj muaj cov yam ntxwv ntawm kev ua haujlwm loj, tsis zoo thermal conductivity thiab muaj zog sib nqus conductivity. Cov hlau muaj qee qhov nyiaj ntawm silicon, uas tuaj yeem txhim kho qhov sib nqus permeability ntawm hlau, txo hysteresis poob, thiab txo qhov poob tam sim no. Cov hlau hluav taws xob muaj 2% mus rau 3% Si, tab sis yuav tsum muaj cov ntsiab lus titanium thiab boron tsawg. Ntxiv silicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Silicon-magnesia hlau yog ib qho siv spheroidizing tus neeg sawv cev. Ferrosilicon muaj barium, zirconium, strontium, bismuth, manganese, tsis tshua muaj ntiaj teb, thiab lwm yam yog siv los ua inoculant hauv cam khwb cia hlau ntau lawm.
4. High-silicon ferrosilicon yog ib qho kev txo qis rau kev tsim cov pa roj carbon monoxide ferroalloys hauv kev lag luam ferroalloy. Ferrosilicon hmoov muaj txog 15% silicon (particle loj<0.2mm) is used as a weighting agent in heavy medium mineral processing.
