Tsawg aluminium ferrosilicon, tseem hu ua qis Al FeSi, yog cov khoom siv dav siv hauv ntau daim ntawv thov kev lag luam. Qhov no ferrosilicon muaj hlau, silicon, thiab ib feem me me ntawm txhuas. Nws yog ib qho tseem ceeb hauv kev tsim cov hlau ntau yam xws li hlau, cam khwb cia hlau, thiab cov hlau tsis muaj hlau. Tsawg Al FeSi paub txog nws cov khoom siv hluav taws xob zoo heev thiab thermal stability. Nov yog qee qhov sib txawv ntawm kev siv qis Al FeSi hauv ntau qhov kev lag luam.
1. Steelmaking
Tsawg Al FeSi ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau. Nws yog siv los ua tus neeg sawv cev deoxidizing kom tshem tawm cov impurities ntawm hlau thiab txhim kho nws qhov zoo. Lub alloy kuj pab tswj cov qoob loj ntawm cov hlau, txhim kho nws cov khoom siv kho tshuab. Cov tuam txhab hlau siv qis Al FeSi los tsim cov hlau silicon, uas yog qhov tseem ceeb rau kev siv hluav taws xob vim nws tsis tshua muaj coercivity thiab siab permeability.
2. Foundry kev lag luam
Tsawg Al FeSi yog ib qho tseem ceeb hauv kev lag luam foundry. Nws yog siv los tsim cov cam khwb cia hlau thiab lwm yam hlau tsis muaj hlau xws li tooj liab thiab txhuas alloys. Cov hlau yog ntxiv rau cov hlau molten kom txo cov ntsiab lus carbon, txhim kho qhov zoo ntawm casting, thiab txo qhov kev pheej hmoo ntawm qhov tsis xws luag. Nws cov ntsiab lus tsis tshua muaj aluminium kuj pab txo qis kev tsim cov dross, txhim kho cov txheej txheem ua haujlwm, thiab txo cov nqi.
3. Kev lag luam vuam
Kev lag luam vuam kuj tau txais txiaj ntsig los ntawm kev siv qis Al FeSi. Lub alloy yog ntxiv rau vuam electrodes kom ua tau zoo heev hluav taws xob conductivity thiab thermal stability. Nws kuj tseem txhim kho cov khoom siv kho tshuab ntawm vuam thiab txo qhov kev pheej hmoo ntawm porosity thiab tawg.
4. Kev lag luam tshuaj
Tsawg Al FeSi yog siv los ua tus neeg sawv cev txo qis hauv kev lag luam tshuaj. Nws muaj kev sib raug zoo siab rau cov pa oxygen, sulfur, thiab lwm yam tsis yog hlau, ua rau nws muaj qhov zoo tshaj plaws rau kev txo cov hlau oxide rau hlau. Cov hlau kuj tseem siv rau hauv kev tsim cov magnesium thiab lwm yam tshuaj tshwj xeeb.
Hauv kev xaus, tsis tshua muaj txhuas ferrosilicon yog ntau yam alloy siv hauv ntau daim ntawv thov kev lag luam. Nws cov khoom tshwj xeeb ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hlau, cam khwb cia hlau, thiab cov hlau tsis muaj hlau. Nws tseem ua haujlwm tseem ceeb hauv kev vuam electrodes thiab kev lag luam tshuaj. Nws cov txiaj ntsig ntau tau ua rau qis Al FeSi ib qho tseem ceeb hauv kev lag luam niaj hnub no.
