Cov ntawv thov thiab cov yam ntxwv hauv cov khoom tseem ceeb FESI

Ferrosilicon, ib qho alloy ntawm hlau (FE) thiab silicon (si), yog ib qho tseem ceeb hauv methopurgy thiab tsim vim yog nws lub dazidizing, alloy-resist cov khoom. Nws cov versatility stems los ntawm cov ntsiab lus Silicon cov ntsiab lus (feem ntau 15% -90% SI) thiab sib txawv hloov zuj zus.

Steelmaking kev lag luam

Cov Ntawv Thov:

Deoxidizer: Tshem tawm cov oxygen los ntawm Molten Steel los tiv thaiv Porosity (Fesi 65-75% yog qhov zoo tshaj plaws).

Alloying Tus Neeg Sawv Cev: Txhim kho cov hlau lub hardness, lub zog, thiab corrosion tsis kam (piv txwv li, hauv stainless hlau).

Tshuaj Tswj Xyuas Kev Tswj Xyuas: Pab tswj cov ntsiab lus carbon hauv steel qhuav.

Cov yam ntxwv tseem ceeb:

Cov ntsiab lus silicon siab (ntau dua lossis sib npaug rau 65% SI) ua kom muaj pa oxygen tau txais txiaj ntsig zoo.

Tsawg impurities (al, p, s) yog qhov tseem ceeb rau cov hlau qib siab.

Exothermic cov tshuaj tiv thaiv thaum deoxidation txo cov nqi zog lub zog.
