High Carbon Ferrochrome Refining Method Smelting Nruab nrab-tsawg Carbon Ferrochrome

Chrome ore refining siab carbon ferrochrome: thaum refining siab carbon ferrochrome nrog chrome ore, lub refining slag muaj loj viscosity thiab siab melting point, thiab cov txheej txheem smelting kub yuav tsum siab dua. Yog li ntawd, lub zog siv hluav taws xob yog siab, lub tshuab hluav taws xob hauv lub neej luv luv, thiab cov ntsiab lus carbon tsis yooj yim los nqis. Oxygen tshuab siab carbon ferrochrome muaj ntau dua superiority, xws li siab productivity, tsis tshua muaj nqi, siab rov qab tus nqi. Tam sim no, txoj kev tsim khoom ib txwm siv lossis electro-silicon cua sov txoj kev. Electrosilicon tshav kub txoj kev yog ua kom alkaline slag nyob rau hauv lub cub hluav taws xob nyob rau hauv cov xwm txheej ntawm silicon nyob rau hauv silicon chromium alloy kom txo tau cov chromium thiab hlau oxides, thiaj li yuav ua tau tsawg carbon ferrochrome.

Oxygen blowing refining of low carbon ferrochrome: Oxygen blowing method of refining low carbon ferrochrome siv cov khoom siv yog lub converter, yog li nws yog hu ua converter method. Raws li txoj kev sib txawv ntawm cov pa oxygen, cov tshuab pa oxygen tuaj yeem muab faib ua plaub yam ntawm sab tshuab, sab saum toj tshuab, hauv qab tshuab thiab sab saum toj thiab hauv qab ob lub tshuab. Peb lub teb chaws txais cov txheej txheem saum tshuab tshuab converter. Oxygen tshuab txoj kev yog tshuab oxygen ncaj qha mus rau hauv cov kua high-carbon ferrochrome kom nws decarburised thiab tsim cov pa roj carbon ferrochrome tsawg. Cov ntsiab lus tseem ceeb hauv cov pa roj carbon monoxide siab yog chromium, hlau, silicon thiab carbon, uas tuaj yeem oxidized. Lub luag haujlwm tseem ceeb ntawm oxidation tshuab siab carbon ferrochrome yog decarbonise thiab khaws cia chromium. Thaum cov pa nkag mus rau hauv cov kua high-carbon ferrochrome, vim hais tias cov ntsiab lus ntawm chromium thiab hlau account rau ntau tshaj 90% ntawm tag nrho cov nyiaj ntawm alloy, yog li thawj oxidation ntawm chromium thiab hlau, thiab ces, cov oxides yuav oxidized tawm. silicon nyob rau hauv lub alloy. Vim yog oxidation ntawm chromium, hlau thiab silicon, qhov kub ntawm lub pas dej molten nce sai, thiab cov tshuaj tiv thaiv decarburisation tsim sai heev. Qhov siab dua qhov kub, qhov zoo dua rau cov tshuaj tiv thaiv decarburisation, thiab nws tuaj yeem cuam tshuam cov tshuaj tiv thaiv oxidation ntawm chromium, thiab cov pa roj carbon tsawg hauv cov hlau tuaj yeem txo qis.
