Dab tsi yog cov kev faib tawm ntawm cov alloys muaj thoob?
Ferrosilicon alloy yog ib qho tseem ceeb alloy cov khoom siv, feem ntau yog siv ua ib qho alsoy ntxiv rau cov hlau. Nws tuaj yeem txhim kho kev ua tau zoo ntawm cov hlau, nce ntxiv nws lub zog thiab hardness, thiab kuj tseem muaj cov yam ntxwv ntawm corrosion tsis kam thiab coj kev tiv thaiv. Raws li cov ntsiab lus sib txawv ntawm silicon thiab hlau hauv ferrosilicon alloys, nws tuaj yeem faib ua cov sib txawv.
1. Zoo tib yam ferrosilicon alloy
Cov lus silicon hauv cov ntsiab lus zoo ib yam ferrosilicon alloy feem ntau dua 40%, thiab cov ntsiab lus hlau qis dua 40%. Qhov no alloy muaj zoo brittleness thiab lub zog thiab yog ib feem siv alloy additive. Nws tuaj yeem txhim kho lub hardness thiab lub zog ntawm steel nyob rau lub steel tsim cov txheej txheem, thiab tseem tuaj yeem txhim kho cov coj ntawm cov hlau. Yog li ntawd, zoo ib yam ferrosilicon alloy yog dav siv nyob rau hauv kev tsim cov khoom steel.
2. High-silicon ferrosilicon alloy
Cov ntsiab lus silicon hauv cov siab-silicon ferrosilicon alloy feem ntau dua li theem 65%%, thiab cov ntsiab lus hlau qis dua 30%. Cov allolo no muaj cov ntsiab lus silicon ntau dua, yog li nws muaj lub zog zoo dua thiab tawv tawv. Nws yog tsuas yog siv nyob rau hauv kev tsim cov tshwj xeeb hom hlau, xws li cov hlau ceev, hnav cov nqi tshwj xeeb, yog li nws tau txais dav dav thiab kev thov hauv kev lag luam steel.
3. Tsawg Silicon ferrosilicon Alloy
Cov ntsiab lus silicon hauv qis silicon ferrosilicon alloy feem ntau qis dua 20%, thiab cov ntsiab lus hlau yog siab dua 80%. Qhov no alloy muaj cov ntsiab lus silicon tsawg, yog li nws muaj kev du dua zoo dua thiab cov yas, thiab tseem muaj zog dua. Low silicon ferrosilicon alloy yog siv rau hauv kev tsim cov hlau tshwj xeeb, thiab lwm yam khoom siv tseem ceeb tshaj plaws hauv thaj chaw tshwj xeeb cov hlau tshwj xeeb.
Feem ntau, ferrosilicon alloys tuaj yeem faib ua allocilicon alloys thiab qis silicon ferrosilicon alloys raws li cov ntsiab lus sib txawv ntawm silicon thiab hlau. Txhua hom ntawm ferrosilicon alloy muaj cov yam ntxwv sib txawv thiab cov ntawv thov, tab sis txhua tus ua lub luag haujlwm tseem ceeb hauv kev lag luam steel.
