Kev siv tseem ceeb ntawm ferrosilicon
Ferrosilicon yog tsim los ntawm coke, steel seem, thiab quartz (los yog silica), thiab yog smelted nyob rau hauv lub cub hluav taws xob. Kev lig kev cai, ferrosilicon yog ua kom zoo los ntawm kev txo cov silicon los ntawm silica uas muaj SIO2. Feem ntau ntawm cov ferrosilicon smelting siv metallurgical coke raws li tus neeg saib xyuas txo thiab steel seem ua tus neeg saib xyuas rau ferrosilicon.
Cov khoom siv raw thiab hluav taws xob siv rau kev tsim khoom ntawm ib tuj ntawm ferrosilicon yog
Silica: 1780-1850kg
Coke: 890-930kg
Steel seem: 220-230kg
Electrode muab tshuaj: 45-55kg
Kev siv hluav taws xob: 8400-9000kwh/t
Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Hauv torrefied steel, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. Brick billet hlau kuj tseem siv hauv steelmaking ua tus neeg sawv cev alloying. Qhov sib ntxiv ntawm qee qhov nyiaj ntawm silicon hauv cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, txhim kho cov permeability ntawm steel, thiab txo cov hysteresis poob ntawm transformer steel. General steel uas muaj silicon {{{0}}}.15 feem pua -0.35 feem pua, cov qauv hlau uas muaj silicon 0.40 feem pua ~ 1.75 feem pua, cov hlau uas muaj silicon 0.30 feem pua ~ 1.80 feem pua, lub caij nplooj ntoos hlav steel muaj silicon 0.40 feem pua ~ 2.80 feem pua, stainless acid-resistant steel uas muaj silicon 3.40 feem pua ~ 4.00 feem pua, kub-resistant steel muaj silicon 1.00 feem pua ~ 3%.
High ferrosilicon los yog siliceous alloy yog siv nyob rau hauv kev lag luam ferroalloy raws li ib tug txo tus neeg sawv cev rau zus tau tej cov carbon ferroalloys tsawg. Ferrosilicon ntxiv rau cam khwb cia hlau tuaj yeem siv los ua cov inoculant ntawm cov hlau nplaum, thiab tuaj yeem tiv thaiv kev tsim cov carbide, txhawb cov nag lossis daus ntawm graphite thiab spheroidization, txhim kho kev ua haujlwm ntawm cam khwb cia hlau.
Tsis tas li ntawd, ferrosilicon hmoov tuaj yeem siv los ua 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 silicon ntshiab rau cov khoom siv hluav taws xob, thiab hauv kev lag luam tshuaj los tsim silicone, thiab lwm yam.
