Kev piav qhia

FeCr Ferrochrome thiab High Carbon Ferrochrome yog cov ntaub ntawv tseem ceeb hauv kev tsim cov hlau tsis muaj steel thiab lwm cov hlau alloy. Ferrochrome yog ib qho alloy ntawm chromium thiab hlau, uas yog tsim los ntawm smelting chromite ore nyob rau hauv lub cub hluav taws xob. High Carbon Ferrochrome yog ib hom Ferrochrome nrog cov ntsiab lus carbon ntawm ib ncig ntawm 6-8%, uas ua rau nws tsim nyog rau kev siv hauv stainless hlau ntau lawm.

Kev tsim khoom ntawm FeCr Ferrochrome thiab High Carbon Ferrochrome koom nrog ob peb kauj ruam. Ua ntej, chromite ore yog mined thiab tom qab ntawd ua tiav kom tshem tawm impurities. Tom qab ntawd cov chromite ore huv si yog tov nrog ib tug txo tus neeg sawv cev, xws li coke los yog charcoal, thiab ib tug flux, xws li limestone, thiab muab tso rau hauv lub cub hluav taws xob. Lub cub tawg yog rhuab mus txog 2000 degree, thiab ib qho hluav taws xob tam sim no tau dhau los ntawm kev sib tov kom yaj cov chromite ore thiab txo cov chromium thiab hlau oxides.

Thaum lub sij hawm smelting txheej txheem, cov pa roj carbon nyob rau hauv tus neeg sawv cev txo reacts nrog cov pa oxygen nyob rau hauv cov oxides los tsim carbon monoxide thiab carbon dioxide. Qhov no txo ​​cov chromium thiab hlau oxides nyob rau hauv qhov sib tov rau hlau daim ntawv, uas ces muab sib xyaw ua FeCr Ferrochrome los yog High Carbon Ferrochrome. Cov hlau molten yog ces tapping thiab txias, feem ntau nyob rau hauv dej los yog ib tug roj -raws li kev daws, los tsim ib tug khoom alloy.

Smelting nrog txo qhov cub, siv coke li txo tus neeg sawv cev, silica los yog bauxite li flux. Slag muaj pes tsawg leeg feem ntau SiO227 ~ 33%, MgO30 ~ 34%, Al2O326 ~ 30%, Cr2O3<9.0%.

Specification

FeCr Ferrochrome thiab High Carbon Ferrochrome muaj ntau yam khoom tseem ceeb, uas ua rau lawv haum rau siv ntau yam kev siv. Ua ntej, lawv muaj kev ua haujlwm siab rau oxidation thiab corrosion, uas ua rau lawv zoo tagnrho rau siv hauv kev tsim cov hlau stainless. Qhov thib ob, lawv muaj cov tawv tawv thiab tawv tawv zoo heev, uas ua rau lawv zoo tagnrho rau kev tsim cov cuab yeej steel thiab lwm yam siab - lub zog alloys. Thaum kawg, lawv muaj lub siab melting point thiab zoo thermal conductivity, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv zus tau tej cov ntaub ntawv refractory thiab lwm yam siab - kub daim ntawv thov.

Hauv kev xaus, FeCr Ferrochrome thiab High Carbon Ferrochrome yog cov ntaub ntawv tseem ceeb hauv kev tsim cov hlau tsis muaj steel thiab lwm cov hlau alloy. Lawv cov khoom tshwj xeeb ua rau lawv zoo tagnrho rau kev siv ntau yam kev siv, thiab lawv cov khoom tsim muaj ob peb kauj ruam nyuaj. Nrog rau qhov kev thov loj zuj zus ntxiv rau siab - cov khoom siv hlau zoo, kev tsim khoom ntawm FeCr Ferrochrome thiab High Carbon Ferrochrome zoo li yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev lag luam steel.

Ntxiv

1. Kev tiv thaiv corrosion siab: FeCr muaj qhov ua haujlwm siab corrosion, uas ua rau nws zoo tagnrho rau siv hauv marine daim ntaub ntawv thiab lwm qhov chaw hnyav.

2. Muaj zog thiab tawv tawv: FeCr yog cov khoom muaj zog thiab tawv heev, uas ua rau nws zoo tagnrho rau cov ntawv thov uas muaj zog thiab lub zog tseem ceeb.

3. Cov cua sov ua haujlwm siab: FeCr muaj qhov ua haujlwm siab rau cov cua sov, uas ua rau nws zoo tagnrho rau siv nyob rau hauv siab -kub daim ntaub ntawv xws li rauv hauv ob sab phlu thiab cua sov ntsiab.

4. Tus nqi-zoo: FeCr yog tus nqi- cov khoom siv tau zoo, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev tsim khoom thiab kev lag luam.
