Ferrochromium muaj 55% -75% magnesium. Nyob ntawm cov ntsiab lus carbon, ferrochromium tuaj yeem muab faib ua cov pa roj carbon monoxide ferrochromium hmoov, nruab nrab-carbon ferrochromium hmoov, qis-carbon ferrochromium hmoov thiab micro-carbon ferrochromium hmoov. Yog li dab tsi yog qhov txawv ntawm lawv?
1. Cov ntsiab lus ntawm cov pa roj carbon monoxide siab yog 4-10%, cov pa roj carbon cov ntsiab lus ntawm cov pa roj carbon ferrochrome yog 05-4%, cov ntsiab lus ntawm cov pa roj carbon tsawg ferrochrome yog {{4} }.15-0.5%, thiab cov ntsiab lus carbon ntawm micro carbon ferrochrome yog 0.15%.
2. Cov txheej txheem smelting ntawm micro-carbon ferrochromium hmoov muaj xws li silicon cua sov txoj kev, kub melting txoj kev, thiab lwm yam. Nws yog tsuas yog siv los txhim kho cov oxidation kuj thiab corrosion kuj ntawm hlau, thiaj li hais tias cov nto ntawm cov hlau yuav tsim ib tug txheej ntawm muaj zog. adhesion nyob rau hauv oxidizing cua. Oxidizing cov yas zaj duab xis, thiab tom qab ntawd oxidation nres lossis oxidation tus nqi qeeb, microcarbon ferrochromium hmoov yog siv los tsim cov hlau tsis muaj steel, hnav-resistant thiab kub-resistant steel.
3. Qhov siv tau ntawm cov pa roj carbon ntau ferrochrome hmoov yog:
1. Aluminium alloy tus neeg sawv cev siv rau cov khoom ncig ntawm pearl steel, alloy steel thiab caij nplooj ntoos hlav steel nrog cov ntsiab lus siab carbon los txhim kho cov kev ua haujlwm ntawm cov hlau thiab txhim kho cov hnav tsis kam thiab lub zog ntawm cov hlau.
2. Siv los ua cov khoom noj rau npua hlau los txhim kho qhov hnav tsis kam thiab hardness ntawm npua hlau, thiab ua rau npua hlau muaj qhov kub thiab txias.
3. Siv los tsim cov ferronickel alloys thiab khoom, tsawg thiab micro carbon ferrochromium hmoov thiab magnesium-muaj raw cov ntaub ntawv.
4. Magnesium-muaj raw cov ntaub ntawv siv los tsim cov hlau chromium los ntawm electrolyzing dej ntsev.
5. Raw cov ntaub ntawv rau stainless hlau phaj nyob rau hauv oxygen tshuab smelters, thiab smelter ua technology ntawm high-carbon ferrochrome hmoov: smelting txoj kev ntawm high-carbon ferrochrome hmoov muaj xws li ironmaking blast furnace txoj kev, cua sov rauv txoj kev, low-temperature plasma method, thiab melting txo. Law thiab lwm yam.
