Carburant

Thaum lub sij hawm smelting txheej txheem, vim tsis yog batching los yog loading, raws li zoo raws li ntau decarburization, tej zaum cov ntsiab lus carbon nyob rau hauv cov hlau tsis tau raws li qhov yuav tsum tau ntawm lub ncov lub sij hawm.Lub sijhawm no, carbon yuav tsum tau ntxiv rau cov kua dej steel.
Feem ntau siv carburetor yog npua hlau, electrode hmoov, roj av coke hmoov, charcoal hmoov thiab coke hmoov.Thaum smelting nruab nrab thiab siab carbon steel qib hauv converter, roj av coke nrog ob peb impurities yog siv los ua carburetor.Qhov yuav tsum tau ua rau cov neeg ua haujlwm carburizing siv nyob rau hauv lub tshuab cua txias converter steelmaking yog kom muaj cov pa roj carbon ntau ruaj khov, cov hmoov tshauv tsawg, cov teeb meem tsis zoo, thiab cov impurities xws li sulfur, phosphorus, thiab nitrogen, thiab kom qhuav, huv si, thiab me me particle loj.
Rau casting, cam khwb cia hlau, cam khwb cia hlau, thiab castings, yuav tsum tau carbon.Raws li lub npe qhia, lub carburetor yog siv los ua kom cov pa roj carbon ntau hauv cov hlau molten.Piv txwv li, nyob rau hauv smelting, cov khoom siv rau cov khoom siv hluav taws xob feem ntau yog npua hlau, seem hlau, thiab cov khoom xa rov qab.Cov ntsiab lus carbon ntawm npua hlau yog siab, tab sis tus nqi yuav khoom yog ib ntu siab dua li ntawm cov khoom seem.Yog li ntawd, nce tus nqi ntawm cov seem hlau, txo cov npua hlau, thiab ntxiv cov carburetor, Nws tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txo cov nqi casting.
Kev siv cov carburizing tus neeg sawv cev tsis tuaj yeem tsuas yog ua rau cov pa roj carbon monoxide poob hauv cov txheej txheem ntawm cov hlau smelting, xyuas kom meej cov ntsiab lus ntawm carbon cov ntsiab lus ntawm cov qib steel tshwj xeeb, tab sis kuj tuaj yeem siv rau kev hloov kho tom qab.Raws li ib qho tseem ceeb raw khoom rau melting molten hlau nyob rau hauv induction furnaces, qhov zoo thiab kev siv ntawm carburetor ncaj qha cuam tshuam lub xeev ntawm molten hlau [2].
Ntxiv ib qib tshwj xeeb ntawm carburizing tus neeg sawv cev rau lub ladle tom qab tshem tawm slag thiab kev kho degassing tuaj yeem kho cov ntsiab lus carbon hauv lub ladle, ua tiav lub hom phiaj ntawm ntau qib hauv ib lub ladle.Cov ntaub ntawv siv rau carburetors feem ntau suav nrog graphite, graphite zoo li cov ntaub ntawv, electrode blocks, coke, silicon carbide, thiab lwm yam ntaub ntawv.Feem ntau siv electrode blocks thiab silicon carbide carburetor muaj qhov zoo ntawm cov ntsiab lus carbon siab thiab muaj zog oxidation tsis kam, tab sis cov txheej txheem ntau lawm yog qhov nyuaj thiab tus nqi siab;Siv cov hmoov coke thiab graphite raws li cov ntaub ntawv carbonization muaj cov nqi tsim khoom qis dua piv rau cov ntaub ntawv xws li electrode blocks, tab sis nws muaj cov hmoov tshauv thiab sulfur siab, cov ntsiab lus carbon tsawg, thiab cov nyhuv carbonization tsis zoo.
