Yuav ua li cas hloov cov recarburizers ntawm molten hlau?

Lub carburizer yog tsim los ntawm cov thee, nrog cov ntsiab lus siab ruaj khov, muaj zog oxidation tsis kam thiab cov ntsiab lus tsis tshua muaj teeb meem, thiab siv los ua tus neeg sawv cev hauv cov txheej txheem smelting. Tus neeg muag khoom recarburizer hais tias nws yog cov khoom siv carbon ntxiv los ua rau cov ntsiab lus carbon uas xav tau hauv cov hlau molten. Ntxiv nws txhim kho cov khoom ntawm cov hlau. Nws yog ib qho tseem ceeb additive nyob rau hauv zus tau tej cov steel.

Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, ntau yam kev siv thev naus laus zis kuj tseem ua kom zoo dua qub. Nyob rau hauv tus txheej txheem ntawm kev siv ntau yam khoom, qhov tshwm sim ntawm ciaj sia taus ntawm fittest kuj yuav tshwm sim, yog li cov khoom zoo yuav tawm. Nyob rau tib lub sijhawm, optimize the processing technology thiab txhim kho ntau lawm efficiency. thiab cov khoom zoo. Hauv cov txheej txheem tshuab ib txwm muaj, cov txheej txheem oxidation ntawm cov pa roj carbon monoxide yog cov khoom siv hluav taws xob tseem ceeb, yog li ua kom cov hlau molten los ntawm qis dua 14 00 degrees Celsius mus rau saum 1600 degrees Celsius tuaj yeem txo cov ntsiab lus carbon. nyob rau hauv cov txheej txheem los ntawm 4 feem pua ​​​​rau 0.2 feem pua, lossis txawm tias 0.1 feem pua. Tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov qib steel feem ntau, yog li kuv xav ntxiv graphite recarburizers hauv cov txheej txheem ntawm cov hlau kom nce cov ntsiab lus ntawm cov hlau thiab ua kom nws ua tau raws li qhov yuav tsum tau ua ntawm lub teb chaws tus qauv ntau.

Tam sim no, cov tuam txhab recarburizer taw qhia tias nws qhov kev thov yog qhov loj hauv peb lub khw, thiab nws muaj ntau yam kev siv. Ntxiv nrog rau kev lag luam steel, nws kuj tuaj yeem siv rau hauv kev tsim khoom ntawm peb lub teb chaws. Rau qee cov txheej txheem smelting, hluav taws xob furnaces, carbon, ua lub luag haujlwm tseem ceeb heev. , yog ib qho khoom siv refractory indispensable nyob rau hauv peb lub teb chaws tam sim no.

Carbonizing cov neeg ua haujlwm rau steelmaking muaj xws li graphite, charcoal, thiab coke. Nyob rau hauv tus txheej txheem ntawm smelting nruab nrab carbon steel thiab siab carbon steel nyob rau hauv oxygen converter, carbonization ntawm tsawg tshauv roj av coke feem ntau yog siv. Cov kev cai rau recarburizers yog cov ntsiab lus siab ruaj khov, cov hmoov tshauv tsawg, cov teeb meem tsis zoo thiab cov impurities xws li sulfur, phosphorus thiab nitrogen, thiab cov khoom me me tom qab ziab. Qhov loj me me yog qhov zoo heev, yooj yim rau hlawv thiab ntab rau saum npoo ntawm cov hlau molten.

Hauv kuv lub teb chaws txoj kev lag luam hlau thiab cam khwb cia hlau, txhawm rau kom ua tau zoo ntawm kev ua haujlwm zoo ntawm cov khoom siv smelted thaum lub sij hawm tsim thiab ua, cov nroj tsuag recarburizer feem ntau yuav tsum nruj me ntsis tswj cov ntsiab lus carbon. Raws li lub npe implies, recarburizer yog ua kom cov pa roj carbon ntsiab lus nyob rau hauv molten hlau. Piv txwv li, nws yog feem ntau siv nyob rau hauv smelting nqi npua hlau, seem hlau, rov qab them nqi, thiab hlau carbon cov ntsiab lus yog siab, tab sis nws yog ib tug kuj siab nyob rau hauv tus nqi ntawm cov khoom seem steel, yog li ua rau kom cov khoom seem ntawm cov hlau thiab txo kom muaj nuj nqis. ntawm npua hlau, Ntxiv cov neeg sawv cev ntawm cov pa roj carbon monoxide tuaj yeem ua lub luag haujlwm hauv kev txo nqi ntawm castings.

Yog li ntawd, nyob rau hauv cov txheej txheem steelmaking, tsis yog tsuas yog cov graphite carburizing tus neeg saib xyuas yuav tsum tau siv, tab sis kuj muaj ntau hom steel thiab carburizing tus neeg sawv cev muaj ntau yam yuav tsum tau. Qhov zoo ntawm tus neeg sawv cev carburizing cuam tshuam qhov zoo ntawm cov hlau mus rau qhov zoo. Nws ua lub luag haujlwm tseem ceeb hauv kev txo qis ntawm cov hlau molten carburizing tus neeg sawv cev.
