Hauv kev tsim cov txheej txheem tsawg txheej txheem hlau,ferrosilicon(Fesi) Ua si lub luag haujlwm tseem ceeb ua ib qho tseem ceeballoying additiveCov. Tsawg alloOlo qauv hlau feem ntau siv cov pa roj carbon Ferro Silic Silo thiabDeagidizers.

Tsawg Carbon Ferro Silicon: Nws yog qhov feem ntau siv ferrosilicon specification nyob rau hauv tsawg alloy qauv txheej txheem hlau. Feem ntau nws cov ntsiab lus silicon yog 60%- 75}%, thiab nws cov peev txheej carbon nyob hauv qab 0.5%. Qhov kev qhia tshwj xeeb ntawm Ferrosilicon yog qhov tsim nyog rau deoxidation thiab kev sib dhos nyob rau hauv kev tsim cov hlau tsis muaj roj av tsawg, tshwj xeeb yog nyob rau hauv kev lag luam cov hlau tsis tshua muaj hlau thiab cov hlau zoo.

Middle Carbon Ferrro Silicon: Qee cov qauv txheej txheem qis ntawm cov hlau uas siv tau siv nruab nrab carbon ferrosilicon thaum cov ntsiab lus ntau silicon. Nws cov ntsiab lus silicon tseem nyob ntawm 60% - 75%, tab sis cov pa roj carbon% me ntsis, feem ntau 1% {%. Nws yog qhov haum rau cov txheej txheem alloying uas qee qhov ntau ntawm cov pa roj carbon thiab silicon yog qhov yuav tsum tau rau cov qib steel.

Lub luag haujlwm ntawm Ferrosilicon hauv kev tsim cov khoom muaj tsawg-alloy qauv txheej txheem

Deoxidation

Deagidation yog txheej txheem tshem tawm cov pa opurities los ntawm Molten Steel hauv cov hlau ua khoom. Ferrosilicon, raws li tus deoxidizer, rov qab nrog cov pa oxygen nyob rau hauv molten steel los tsim cov tshuab oxide (sidio₂) thiab tshem tawm cov pa los ntawm cov hlau. Rau cov qauv siv tsawg-alloy qauv hlau, tshem tawm cov pa roj oxygen yog cov kauj ruam tseem ceeb los txhim kho cov hlau, thiab txhim kho cov cuab yeej siv tshuab ntawm cov hlau.

Sib ntxaws

Silicon yog ib qho ntawm cov khoom siv uas nquag siv hauv cov hlau tsis muaj hlau. Ntxiv ferrosilicon tuaj yeem nce cov ntsiab lus silicon hauv Molten hlau, yog li kev txhim kho cov oxidation tsis kam, corrosion tsis kam thiab siab-kub lub zog ntawm cov hlau. Qhov kev sib ntxiv ntawm silicon kuj tseem pab txhim kho cov tshuab luam ntawv ntawm cov hlau thiab nce lub hardness ntawm cov hlau.

Tswj cov ntsiab lus ntawm lwm cov khoom hauv cov hlau

Hauv cov hlau smelting, ferrosilicon tsis tsuas yog muab cov kev sib npaug ntawm lwm cov ntsiab lus ntawm lwm cov ntsiab lus ntawm lwm cov khoom sib xws (etc.)

Txhawb nqa cov xim ntawm Molten Steel

Qhov sib ntxiv ntawm Ferrosilicon tuaj yeem txhim kho cov dej ntawm Molten Steel, pab cov khaub ncaws hnav ua ke ntawm cov txheej txheem casting, thiab txo cov kab lis kev cai sib xyaw ua ke xws li pores thiab suav nrog.

Txhim kho kev ua haujlwm txias ntawm cov hlau

Silicon Alloy Steel muaj cov khoom siv zoo thiab kev ua tau zoo thaum ua haujlwm txias. Qhov sib ntxiv ntawm silicon txhim kho kev ua haujlwm txias ntawm cov hlau tsis muaj zog ntawm cov hlau uas yuav tsum tau muab cov khaub ncaws txias, kev kos duab txias thiab lwm yam txheej txheem ua.
