ferrosilicon yog dab tsi?
Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Ferrosilicon yog hlau silicon alloy ua los ntawm smelting coke, steel shavings, quartz (los yog silica) raws li raw cov ntaub ntawv nyob rau hauv lub cub hluav taws xob;
Kev siv ferrosilicon:
1. Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Hauv steelmaking, ferrosilicon yog siv rau nag lossis daus deoxidization thiab diffusion deoxidization. Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking.
2. Siv los ua inoculant thiab spheroidizer hauv kev lag luam cam khwb cia hlau. Hauv kev tsim cov hlau nplaum, 75 silicon hlau yog ib qho tseem ceeb inoculant (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev.
3. Siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen siab, tab sis cov pa roj carbon ntsiab lus ntawm siab silicon ferrosilicon kuj tsawg heev. Yog li ntawd, siab silicon ferrosilicon (los yog siliceous alloys) yog ib tug nquag siv los txo tus neeg sawv cev nyob rau hauv zus tau tej cov low-carbon ferroalloys nyob rau hauv lub ferroalloy kev lag luam.
