Ferroalloy yog ib qho tseem ceeb thiab tseem ceeb raw cov ntaub ntawv rau hlau thiab steel kev lag luam thiab machinery casting kev lag luam. Nrog rau kev txhim kho tas mus li thiab nrawm ntawm Tuam Tshoj txoj kev lag luam hlau thiab hlau, ntau yam ntawm cov hlau tau nthuav dav thiab kev txhim kho zoo, uas ua rau muaj kev xav tau ntau dua rau cov khoom ferroalloy.
(1) Siv los ua deoxidizer. Lub zog sib xyaw ua ke ntawm ntau yam hauv cov hlau rau oxygen, piv txwv li deoxidation muaj peev xwm, los ntawm qaug zog mus rau qhov muaj zog raws li hauv qab no: chromium, manganese, carbon, silicon, vanadium, titanium, boron, txhuas, zirconium, calcium. General steel deoxygenation feem ntau siv los ntawm silicon, manganese, aluminium, calcium uas muaj hlau alloy.
(2) Siv los ua tus neeg sawv cev alloying. Siv los kho cov tshuaj muaj pes tsawg leeg ntawm cov hlau los ua cov hlau alloying cov ntsiab lus lossis cov alloys hu ua alloying agent, feem ntau siv alloying ntsiab yog silicon, manganese, chromium, molybdenum, vanadium, titanium, tungsten, cobalt, boron, niobium thiab lwm yam.
(3) Siv los ua cov khoom siv hluav taws xob inoculant. Txhawm rau hloov cov txheej txheem solidification, feem ntau ntxiv ua ntej pouring tej yam hlau alloys raws li lub nucleus, tsim ntawm grain centre, thiaj li hais tias tus tsim ntawm graphite yuav zoo dispersion, grain refinement, yog li txhim kho cov kev ua tau zoo ntawm lub casting.
(4) Siv los ua tus neeg sawv cev txo qis. Ferrosilicon tuaj yeem siv los ua tus neeg sawv cev txo qis rau kev tsim cov ferromolybdenum, ferrovanadium thiab lwm yam ferroalloys, thiab silicon chromium alloy thiab silicon manganese alloy tuaj yeem siv los ua tus neeg saib xyuas kom txo qis cov pa roj carbon ferrochrome thiab nruab nrab-tsawg carbon ferromanganese, raws.
(5) Lwm yam kev siv. Hauv kev lag luam uas tsis yog-ferrous metallurgy thiab tshuaj lom neeg, ferroalloys kuj tau siv ntau thiab ntau dua.
