Daim ntawv thov Ferrosilicon

Ferrosilicon yog dav siv nyob rau hauv steel kev lag luam, foundry kev lag luam thiab lwm yam kev lag luam ntau lawm.
Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Nyob rau hauv lub teeb steel, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking. Ntxiv qee qhov nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm transformer steel. General steel muaj {{0}}.15%-0.35% silicon, cov qauv hlau muaj 0.40%-1.75% silicon , cov cuab yeej hlau muaj 0.30% -1.80% silicon, caij nplooj ntoos hlav steel muaj 0.40% -2.80% silicon, thiab stainless acid-resistant steel muaj Silicon 3.40% ~ 4.00% , kub-resistant steel muaj silicon 1.00% ~ 3.00%, silicon steel muaj silicon 2% ~ 3% lossis siab dua.
High-silicon ferrosilicon los yog siliceous alloys yog siv nyob rau hauv kev lag luam ferroalloy li txo cov neeg ua hauj lwm rau zus tau tej cov carbon ferroalloys tsawg. Ferrosilicon tuaj yeem siv los ua ib qho inoculant rau ductile hlau thaum ntxiv rau cam khwb cia hlau, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, thiab txhim kho kev ua haujlwm 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 semiconductor ntshiab silicon thiab hauv kev lag luam tshuaj los tsim cov khoom siv silicone, thiab lwm yam.
Hauv kev lag luam steelmaking, kwv yees li 3 mus rau 5kg ntawm 75% ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim.
Melting point: 75FeSi yog 1300 degree
Ferrosilicon muaj me me ntawm phosphorus hlau tebchaw, xws li calcium phosphide. Yog hais tias nws ntub dej thaum lub sij hawm thauj mus los los yog warehouse cia, nws muaj peev xwm tso phosphine, lom neeg nyob rau hauv lub warehouses los yog nyob ib ncig ntawm nws. Phosphine lom tuaj yeem ua rau tuag taus.
