Tus yuam sij sib txawv ntawmChrome Orethiabferrioromelus dag nyob rau hauv lawv muaj pes tsawg leeg, kev ua, thiab siv:
Chrome Ore
Zaj piav: Ore chrome yog ib qho ntxhia feem ntau tsim ntawmchromite (Fecr₂o₄), uas muaj chromium, hlau, thiab cov pa oxygen.
Lub hauv paus: Mined los ntawm lub ntiaj teb crust.
Tab tom ua: Feem ntau cov neeg tau txais txiaj ntsig (crushing, sib tsoo, thiab kev sib tsoo) kom nce cov ntsiab lus chromium ua ntej siv.
Kev siv: Feem ntau yog siv los ua cov khoom siv raw rau ua ferrioRome thiab lwm cov khoom chromium raws li cov khoom lag luam, suav nrog cov khoom siv tsis xeb thiab cov khoom siv refractory.
Ferrocrome (FECR)
Zaj piav: Ferrocrome yog ib qhoAlloy ntawm chromium thiab hlau, muaj nruab nrab ntawm50% rau 70% chromium, tsim los ntawm smelting chrome ore nrog tus neeg sawv cev txo tus nqi txo (xws li Coke) hauv kev sib xyaw hluav taws xob ua kom sov.
Tab tom ua: Chrome ORE yog ua tiav nyob rau hauv high-rurnaces kom tshem tawm oxygen thiab tsim lub hlau-chromium alloy.
Kev siv: Feem ntau siv nyob rau hauv lubzus tau tej cov steel hlau, raws li chromium txhim kho corrosion, hardness, thiab kav ntev. Nws tseem siv rau kev tsim khoom ntawm cov hlau tshwj xeeb thiab cov alloys.
| Yam zoo | Chrome Ore | Ferriorome |
