Ferrosilicon npas, uas yog nias los ntawm ferrosilicon hmoov thiab ferrosilicon nplej, yog siv los ua deoxidizer thiab alloying tus neeg sawv cev nyob rau hauv cov txheej txheem steelmaking thiab yuav tsum tau deoxidized nyob rau tom qab theem ntawm steelmaking kom tau hlau nrog tsim nyog tshuaj muaj pes tsawg leeg thiab xyuas kom meej cov hlau zoo. .

Ferroalloys hauv kev lag luam foundry li steelmaking nucleus inoculant. Ib qho ntawm cov kev ntsuas los hloov qhov kev ua tau zoo ntawm cov hlau cam khwb cia hlau thiab cam khwb cia hlau yog hloov cov casting solidification tej yam kev mob nyob rau hauv thiaj li yuav hloov lub solidification tej yam kev mob, feem ntau nyob rau hauv lub casting ua ntej ntxiv tej yam ferroalloys li nuclei, tsim ntawm grain centre, thiaj li hais tias tsim. ntawm graphite ua me me dispersed, grain refinement, yog li txhim kho cov kev ua tau zoo ntawm cov casting.

Silicon hlau hmoov, raws li ib qho tseem ceeb muaj raw khoom, plays lub luag hauj lwm tseem ceeb nyob rau hauv lub teb ntawm refractories. Nws daim ntawv thov yuav muaj kev cuam tshuam rau kev ua haujlwm ntawm cov khoom siv refractory.

Ferro-tungsten ntau lawm txoj kev yog agglomeration txoj kev, hlau extraction txoj kev thiab txhuas tshav kub txoj kev.

Calcium silicate cored hlau (CaSi Cored Wire) yog ib hom cored hlau siv hauv steelmaking thiab casting daim ntaub ntawv. Nws yog tsim los ua kom paub meej cov nyiaj calcium thiab silicon rau hauv molten hlau los pab hauv deoxidation, desulphurization thiab alloying. Los ntawm kev txhawb cov kev cuam tshuam tseem ceeb no, cored hlau txhim kho qhov zoo, huv si thiab cov khoom siv kho tshuab ntawm cov hlau.

Vanadium yog ib qho tseem ceeb alloying ntsiab feem ntau siv hauv kev lag luam steel. Vanadium-muaj steel muaj cov khoom zoo xws li lub zog siab, siab tawv, thiab hnav tsis kam, yog li nws yog dav siv hauv tshuab, tsheb, nkoj tsim, railways, aviation, txuas hniav, tshuab hluav taws xob, kev tiv thaiv kev lag luam thiab lwm yam lag luam.
