ferroalloy yog dab tsi? Dab tsi yog siv? Wb kawm:
Ferroalloy nyob rau hauv kev txiav txim siab dav hais txog ib yam khoom ntxiv rau cov hlau molten li deoxidizer thiab cov khoom siv ntxiv los ua kom cov hlau muaj qee yam ntxwv lossis ua tau raws li cov cai. Ib qho nruab nrab alloy tsim los ntawm hlau thiab ib lossis ntau lub ntsiab lus, feem ntau yog siv hauv cov hlau thiab hlau smelting. Hauv kev lag luam hlau thiab hlau, txhua tus tswv alloys rau steelmaking, txawm tias muaj hlau los yog tsis (xws li silicon calcium alloy), feem ntau hu ua "ferroalloy". Kev lig kev cai, qee cov khoom siv hlau ntshiab thiab oxide additives kuj suav nrog.
Ferroalloys feem ntau yog siv los ua deoxidizer: tshem tawm cov pa oxygen los ntawm cov hlau molten hauv cov txheej txheem steelmaking. Qee cov ferroalloys tuaj yeem tshem tawm lwm yam impurities hauv hlau, xws li sulfur thiab nitrogen. Alloy additive: Raws li qhov yuav tsum tau muaj ntawm cov hlau muaj pes tsawg leeg, cov ntsiab lus alloy yog ntxiv rau cov hlau los txhim kho cov khoom ntawm cov hlau. Inoculant: ntxiv molten hlau ua ntej cam khwb cia hlau casting los txhim kho cov crystalline qauv ntawm lub casting.
