Tus qauv zoo ntawm ferrosilicon 75B feem ntau suav nrog cov hauv qab no:
Tshuaj muaj pes tsawg leeg: Cov tshuaj muaj pes tsawg leeg ntawm ferrosilicon 75B yuav tsum ua tau raws li cov kev cai tshwj xeeb, suav nrog cov ntsiab lus ntawm silicon (Si), aluminium (Al), calcium (Ca), manganese (Mn), chromium (Cr), phosphorus (P), sulfur ( S) thiab carbon (C). Tshwj xeeb, cov ntsiab lus silicon hauv ferrosilicon 75B yuav tsum ntau dua 75%, cov ntsiab lus txhuas yog 1.46%, cov ntsiab lus calcium yog 0.56%, manganese cov ntsiab lus yog 0.14%, chromium cov ntsiab lus yog 0.07%, cov ntsiab lus phosphorus yog 0.{15}}14%, cov ntsiab lus sulfur yog 0.003%, thiab cov ntsiab lus carbon yog 0.072%. Kev tswj xyuas meej ntawm cov khoom no yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo thiab kev siv ferrosilicon 75B.
Daim ntawv thov teb: ferrosilicon 75B yog dav siv nyob rau hauv steel kev lag luam, foundry kev lag luam thiab lwm yam industrial ntau lawm. Hauv kev lag luam steel, ferrosilicon 75B, ua tus deoxidizer thiab alloying tus neeg sawv cev, tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau, txhim kho cov hlau nplaum permeability ntawm hlau, thiab txo cov hysteresis poob ntawm transformer hlau. Nyob rau hauv kev lag luam foundry, ferrosilicon 75B tuaj yeem muab ntxiv ua ib qho inoculant los txhawb cov nag lossis daus thiab spheroidization ntawm graphite thiab txhim kho cov khoom ntawm cam khwb cia hlau. Tsis tas li ntawd, high-silicon ferrosilicon los yog siliceous alloys yog siv los txo cov neeg ua haujlwm hauv kev lag luam ferroalloy los tsim cov pa roj carbon tsawg ferroalloys.
Kev siv: Hauv kev lag luam steelmaking, kwv yees li 3-5 kg ntawm 75% ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim, uas qhia tau hais tias qhov tseem ceeb thiab kev siv loj ntawm ferrosilicon 75B hauv cov txheej txheem steelmaking.
Hauv cov ntsiab lus, tus qauv zoo ntawm ferrosilicon 75B tsis tsuas yog cuam tshuam nrog kev tswj hwm ntawm nws cov tshuaj muaj pes tsawg leeg, tab sis kuj suav nrog nws daim ntawv thov hauv kev lag luam sib txawv thiab nws cov khoom siv hauv cov txheej txheem steelmaking. Cov yam tseem ceeb no ua ke kom ntseeg tau tias kev ua tau zoo thiab kev siv ferrosilicon 75B tuaj yeem ua tau raws li ntau yam kev lag luam.
