Dab tsi yog ferrocrome (FECR)?

Ferrocrome (FECR) yog xim hlau alloy feem ntau tsim ntawm cov hlau (fe) thiab chromium (nrog chromium cov ntsiab lus feem ntau xws li 50% txog 70%. Qeb cov nqi ntawm lwm cov ntsiab lus (piv txwv li, sinb, silicon, lossis leej faj) tej zaum yuav muaj nyob ntawm cov qhab nia, uas tau txiav txim siab los ntawm nws cov kev npaj siv. Nws yog tsim los ntawm smelting chromite ore (carbon) nrog coke (carbon) hauv high {

Ferrocrome yog cov khoom siv raw qhov tseem ceeb hauv metallurgy, nrog ntau tshaj 85% ntawm lub ntiaj teb ntau lawm siv hauv kev tsim cov hlau. Cov ntawv thov tseem ceeb muaj xws li:

​Stainless hlau ntau lawm: Qhov tseem ceeb rau kev tsim cov hlau tsis muaj stainless (uas yuav tsum muaj 10-30% CR). Chromium hauv Ferriochrome Enhats corrosion thiab oxidation tsis kam, muab cov hlau tsis muaj kev kos npe rau nws lub npe.

​Alloy Steels: Ntxiv rau cov cuab yeej siv hlau, siab - cov qauv ceev, thiab kub, thiab cov cuab yeej kub, thiab muaj Machinery).

​Khoom nyiam tshaj lij: Siv hauv Aerospace thiab cov khoom siv rau cov tshuaj engineering engine

​Ntawv refactories: Qee zaum siv nyob rau hauv high -} kev siv hluav taws xob (piv txwv li, kilns) rau nws qhov ruaj khov.

​Ntau lawm: Nws yog lub zog - ntso rau cov khoom lag luam (xav tau ~ 4,000 ib tev) vim yog qhov kub thiab txias xav tau los txo chromite ore.

​Ee cia siab​: High-grade chromite ore (>48% CR₂O₃) yog tsawg, nrog ~ 90% ntawm ntiaj teb cov peev txheej muaj nyob rau hauv South Africa, Kazakhstan, thiab Qaib ntxhw. Qis - qib ees xav tau kev ua ntxiv, nce nqi.

​Cov menyuam kawm qib: Cov ntsiab lus ntawm cov ntsiab lus carbon (piv txwv li, siab}} carbon fecbon fecbon / silicon fecr rau alloys tshwj xeeb).

​Lub magnetism: Sib nqus vim nws cov ntsiab lus hlau (chromium tsis muaj zog tiv thaiv {}} ferromagnetic, tab sis hlau yeej sib txawv hauv FECR).

​Kev sib tw ib puag ncig: Cov Khoom Siv Ntau Lawm

Hauv ntej, Ferrroidrome yog qhov tseem ceeb rau kev niaj hnub me me, txawm tias nws cov khoom siv ntau lawm ua rau nws lub siab {{tus nqi, cov khoom siv tseem ceeb.
