Ferroalloys yog ntau yam khoom xws li silicon hlau, chromium hlau, manganese hlau, silicon-calcium alloy thiab lwm yam. Ferroalloys ua lub luag haujlwm tseem ceeb hauv kev deoxidising, purification, txo nqi thiab kev txhim kho zoo ntawm cov txheej txheem steelmaking.
Kev tsim cov ferroalloys yog ib txoj kev siv zog heev. Feem ntau, lub qhov cub submerged arc yog siv los tsim cov khoom no, qhov twg carbon yog rhuab. Qee qhov qis carbon ferroalloys yuav tsum tau smelting ntawm intermediate alloy ua ntej lawv tuaj yeem tsim los ntawm thermal hlau txo txoj kev. Tib ferroalloy tuaj yeem ua tau zoo sib txawv. Qhov siab dua cov ntsiab lus ntawm cov alloy, cov ntsiab lus ntawm cov pa roj carbon, phosphorus thiab lwm yam impurities, thiab tus nqi siab dua. Qhov no kuj muaj txiaj ntsig zoo rau kev tsim steel. Ferroalloys yog siv nyob rau hauv steelmaking, yog li nws yog ib qho tsim nyog los tsim cov qib tsim nyog ntawm ferroalloys raws li cov kev cai ntawm qib steel. Qhov no yuav txo tus nqi ntawm steelmaking. Tom qab ua tiav ntawm ferroalloys yuav tsum tau muab faib raws li qhov muaj pes tsawg leeg thiab particle loj / zoo rau kev siv tau zoo. Qhov loj me me ntawm ferroalloys yog 10-50 hli. Qhov no tso cai rau cov muaj pes tsawg leeg ntawm cov hlau molten thiab ferroalloys kom sib npaug ntawm cov txheej txheem steelmaking, yog li txo qhov poob. Ferroalloys yuav tsum tau ci ua ntej siv los txo cov roj nkag mus rau hauv cov hlau molten.
