Daim ntawv thov ntawm Ferrosilicon

Ferrosilicon yog dav siv hauv kev lag luam steel, kev lag luam casting, thiab lwm yam kev lag luam.
Ferrosilicon yog ib qho tseem ceeb Oxygen scavenger hauv kev lag luam steel. Nyob rau hauv lub teeb steel, ferrosilicon yog siv rau nag lossis daus deoxygenation thiab diffusion deoxygenation. Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho nws lub zog, hardness, thiab elasticity, nce nws cov hlau nplaum permeability, thiab txo cov hysteresis poob ntawm transformer steel. General steel muaj {{0}}.15 feem pua ​​-0.35 feem pua ​​​​silicon, structural steel {0.40 feem pua ​​-1.75 feem pua ​​silicon, Cov cuab yeej steel 0.30 feem pua ​​-1.80 feem pua ​​silicon, caij nplooj ntoos hlav steel 0.40 feem pua ​​-2.80 feem pua ​​silicon, stainless acid resistant steel 3.40 feem pua ​​-4.00 feem pua ​​silicon, kub resistant steel 1.00 feem pua ​​-3.00 feem pua ​​silicon, silicon steel 2 feem pua ​​-3 feem pua ​​silicon lossis ntau dua.
High silicon ferrosilicon lossis siliceous alloys yog siv los txo cov neeg ua haujlwm hauv kev tsim cov pa roj carbon tsawg ferroalloys hauv kev lag luam ferroalloy. Ntxiv silicon hlau rau cam khwb cia hlau tuaj yeem ua tus inoculant rau ductile hlau, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb graphite nag lossis daus thiab spheroidization, thiab txhim kho cov khoom ntawm cam khwb cia hlau.
Tsis tas li ntawd, ferrosilicon hmoov tuaj yeem siv tau raws li lub sijhawm ncua kev lag luam hauv kev lag luam ntxhia thiab ua cov txheej rau vuam rods hauv kev lag luam vuam pas nrig; High silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam hluav taws xob los npaj cov khoom siv hluav taws xob ntshiab silicon, thiab hauv kev lag luam tshuaj los tsim cov khoom siv silicone thiab lwm yam khoom.
Hauv kev lag luam steelmaking, kwv yees li 3-5 kg ntawm 75 feem pua ​​​​ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim.
Melting point: 1300 degree rau 75FeSi
Cov hlau sib txuas uas muaj me me ntawm phosphorus hauv ferrosilicon, xws li Calcium phosphide, tuaj yeem tso Phosphine thiab tshuaj lom neeg nyob hauv lossis ib puag ncig lub tsev khaws khoom yog tias lawv cuam tshuam nrog cov dej noo thaum thauj los ntawm tsheb lossis cia hauv lub tsev khaws khoom. Phosphine lom heev tuaj yeem ua rau tuag taus.
