Ferrroalloys - yog alloys ntawm ib lossis ntau dua cov hlau lossis tsis yog xim hlau. Lawv tsis tuaj yeem siv ncaj qha raws li cov ntaub ntawv hlau, tab sis feem ntau yog siv los ua deoxidizers thiab nruab nrab raw cov ntaub ntawv rau cov neeg sawv cev hauv cov hlau.
(1) siv los ua tus neeg saib xyuas dazide. Thaum cov hlau tsim, impurities xws li carbon thiab phosphorus nyob rau hauv lub molten hlau yog oxidized. Thaum cov txheej txheem oxidation ua tiav, oxygen nkag mus rau cov hlau molten. Yog tias cov oxygen tseem nyob hauv tus hlau, nws tseem ceeb txo nws cov kev ua tau zoo. Yog li ntawd, nws yog ib qho yuav tsum tau ntxiv cov ntsiab uas muaj cov khoom siv khi loj nrog cov khoom lag luam tawm thiab cov khoom lag luam deox tau yooj yim, yog li txo cov ntsiab lus pa ntawm Molten hlau. Tus txheej txheem no yog hu ua steel deoxidation. Cov ntsiab lossis cov alloys siv rau deoxidation hu ua deoxidizers. Feem ntau siv deoxidants yog manganese, silicon thiab txhuas. Cov ntsiab lus no feem ntau ntxiv rau Molten Steel nyob rau hauv daim ntawv ntawm cov hlau alloys fe {} mn, fe - Si thiab al. Muaj zog lub caij nyoog muaj peev xwm khi nrog oxygen, ntau dua nws cov ntsiab lus hauv cov hlau thiab qhov zoo dua nws cov nyhuv dazidizing.
(2) siv los ua ib qho kev sib dhos: cov khoom siv alloy tsis tsuas yog txo cov khoom tsis zoo hauv cov hlau, tab sis kuj tau tswj hwm nws cov tshuaj muaj kuab lom. Cov ntsiab lus lossis cov alloys tau siv los kho cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau thiab alloy nws yog hu ua cov neeg sawv cev. Cov ntsiab lus uas siv tau siv xws li silicon, mangybenum, coladium, tungsten, tungsten, titanium, coranium, coradium, tungsten, tungsten, tungsten, tunanium, coradium, coralys alloy cov ntsiab lus muaj cov yam ntxwv sib txawv thiab kev siv.
(3) Kev txhim kho cov txheej txheem casting thiab cov khoom ntawm cov chaw castecting= ferrroalloys kuj tseem tuaj yeem siv los txhim kho cov txheej txheem casting txhim kho thiab cov khoom ntawm cov chaw castings.
(4) Raws li tus neeg sawv cev txo tus nqi txo: Ferrosilicon tuaj yeem siv los ua tus neeg sawv cev txo qis ntawm cov ferroalloys xws li ferromolybdenum thiab ferrovanadium. Silicon-chromium alloys and silicon-manganese alloys can be used as reducing agents for ferrochrome refining and ferromanganese refining, respectively.
(5) Lwm Yam Siv: Ferrroalloys tseem muaj siv dav hauv lwm qhov kev lag luam. Piv txwv li, ferrosilicon hmoov tuaj yeem siv los ua kev ntxiv hauv cov txheej txheem hluav taws xob hauv kev lag luam vuam. Hauv kev ua lag luam pob zeb ua lag luam, ferrosilicon hmoov tuaj yeem siv los ua kev tsim kho hluav taws xob, tom qab kev ua tiav, tuaj yeem siv ua silicon tauv. Ob lub ntsiab ob txhais tau yuav ua ke ua ke los ua cov hlau kub ua rau hlau, xws li Cr20NI80.
