Ferro alloy, feem ntau hu ua ferroalloys, yog cov ntaub ntawv tseem ceeb ntawm cov hlau uas ua lub luag haujlwm tseem ceeb hauv kev tsim steel thiab kev lag luam casting. Cov alloys no yog tsim los ntawm kev sib txuas cov hlau nrog lwm cov hlau los yog cov hlau tsis yog hlau, uas ua rau muaj ntau hom thiab kev faib tawm.
Ua ntej, ferro alloy tuaj yeem categorized raws li lawv cov khoom tseem ceeb. Piv txwv suav nrogferro silicon, ferromanganese, ferro chrome, ferrovanadium, ferrotitanium, ferrotungsten, thiab ferromolybdenum. Txhua hom ferroalloy muaj cov tshuaj lom neeg tshwj xeeb thiab cov khoom siv lub cev, ua rau lawv haum rau ntau yam kev lag luam.
Thib ob, ferro alloy kuj tuaj yeem raug cais raws li lawv cov ntsiab lus carbon, suav nrog cov pa roj carbon siab, nruab nrab-carbon, qis-carbon, micro-carbon, thiab ultra-micro-carbon ntau yam. Cov ntsiab lus carbon sib txawv endow ferro alloy nrog cov kev siv sib txawv thiab cov yam ntxwv hauv kev tsim cov hlau.
Tsis tas li ntawd, ferroalloys raug cais raws li lawv txoj kev tsim khoom, uas suav nrog lub tshuab hluav taws xob ferroalloys, hluav taws xob rauv ferroalloys, metallothermic txheej txheem ferroalloys, nqus cov khoom hauv xeev txo ferroalloys, converter ferroalloys, thiab electrolytic ferroalloys. Txhua txoj kev tsim khoom muaj cov txheej txheem tshwj xeeb thiab daim ntawv thov scopes.
Hauv kev tsim cov hlau, ferro alloy feem ntau yog cov deoxidizers thiab alloying agents. Raws li deoxidizers, lawv tshem tawm cov pa oxygen thiab lwm yam teeb meem impurities los ntawm cov hlau, kom ntseeg tau qhov zoo ntawm cov khoom kawg. Raws li cov neeg ua haujlwm alloying, ferroalloys txo cov impurities hauv steel thiab kho nws cov tshuaj muaj pes tsawg leeg kom tau raws li ntau yam kev lag luam.
Hauv kev lag luam casting, ferroalloy kuj ua lub luag haujlwm tseem ceeb. Lawv yog siv los ua inoculants los txhim kho cov kev ua tau zoo ntawm cam khwb cia hlau thiab cam khwb cia hlau los ntawm refining lub grain qauv, yog li ua kom lub zog thiab toughness ntawm castings. Tsis tas li ntawd, ferroalloy ua raws li alloy additives nyob rau hauv cov ntaub ntawv casting, tso cai rau kev hloov ntawm lawv cov tshuaj muaj pes tsawg leeg thiab txhim kho lawv cov khoom.
Tshaj lawv cov ntawv thov hauv kev lag luam steel thiab casting, ferroalloy tseem ceeb hauv lwm qhov chaw. Hauv non-ferrous metallurgy thiab tshuaj lom neeg kev lag luam, ferro alloy yog dav siv. Piv txwv li, nruab nrab- thiab qis-carbon ferromanganese yog qhov tseem ceeb rau kev tsim cov vuam electrodes, thaum tshwj xeeb ferro alloy yog qhov tseem ceeb rau kev tsim cov khoom kub-resistant.
Hauv cov ntsiab lus, ferroalloy yog cov khoom siv ntau yam uas ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev tsim khoom lag luam. Lawv ntau yam ntawm cov hom thiab daim ntawv thov tseem ceeb pab rau txoj kev loj hlob thiab kev loj hlob ntawm steel kev lag luam thiab lwm yam kev lag luam sectors.
