Los ntawm kev ntxiv cov pa siab ntau dua - feem ntau yog tshaj 99.5%) rau cov cua sov tuaj yeem txhim kho cov txheej txheem hlau ua kom loj dua. Nce cov pa oxygen tuaj yeem txo cov Coke tau noj (txog {%), thaum ua npua ua npua thiab lub neej ua kom sov.

Oxygen Converter Steelmaking (LD Txoj Kev)
Oxidation ntawm carbon, silicon, thiab phosphorus: tom qab cov pa roj carbon ntau dua li cov pa roj carbon monoxide thiab, nws muaj kev sib zog ua ke nrog cov roj carbon monoxide, Oxygen concentration ncaj qha cuam tshuam cov tshuaj tiv thaiv tus nqi thiab decarburization efficiency. Cov kev xav tsis txaus yuav ua rau cov tshuaj tiv thaiv ncua, thiab cov siab ntau dhau yuav ua rau muaj kev sib cais.
Tswj Qhov Kub
Cov cua sov tso tawm los ntawm oxygen combusion (account rau ntau dua 70% ntawm cov cua sov ({}

Thaum cov pa roj oxygen thiab roj (cov roj nkev) tau sib xyaw thiab hlawv, feem ntau}%) kom ua kom tiav qhov kev sib txuas ua haujlwm thiab qhov kub thiab txias. Cov kev xav tsis txaus yuav ua rau tsis tiav kev sib tshuam ntawm cov roj, thiab ntau dhau kev nce siab yuav ua rau muaj kev kub ntxhov lossis tawg.
Oxidation Decarburization
Cov pa oxygen koom nrog oxidation cov tshuaj tiv thaiv ntawm Molten hlau, thiab cov kev ntsuas cov roj carbon cov txiaj ntsig txo qis raws li qhov kev thov rau cov qib steel.
Refining thiab Deoxidation txheej txheem
Hlau Deoxidation Steel
Nag lossis daus Deagidation: Thaum ntxiv deoxidizers xws li txhuas thiab silicegen concentrusions, uas cuam tshuam rau lub zog thiab cov hlau sib xyaw ntawm cov hlau.
Lub tshuab nqus tsev deoxidation: Los txo lub siab nyob rau hauv lub cub hluav taws (xws li lub tshuab nqus tsev (xws li ua rau khiav tawm. Nyob rau lub sijhawm no, cov oxygen convener yuav tsum qis dua 0. 1% los txo cov oxidary thib ob ntawm Molten hlau.
Oxide Inclus tswj
Excessive oxygen (>{{0 {0}}. 005%) yuav ua rau feo thiab lwm cov oxide suav nrog hauv cov hlau Molten, txo qis. Cov ntsiab lus oxygen xav tau kev tswj hwm nyob rau hauv lub hom phiaj los ntawm kev ua txhaum cai xws li swb thiab argon tshuab thiab nplawm.
Kev Tswj Xyuas thiab Kev Nyab Xeeb Kev Nyab Xeeb
Kev tshuaj xyuas lub sijhawm tiag tiag ntawm cov pa oxygen
Sensor technology: Electrochemical sensors (such as AO-03) and laser analyzers (such as Xi'an Jishansi Equipment) can monitor the oxygen concentration in the furnace in real time (range 0-100%) to ensure combustion efficiency and safety.
Kev Nyab Xeeb Theem: Oxygen concentration ntau tshaj 23% yog feem ntau yuav tsum tau tswj kev pheej hmoo txaus ntshai thiab yuav tsum tau tswj tau nyob rau hauv kev nyab xeeb los ntawm qhov chaw nyab xeeb los yog inert gasilution.
Nitrogen tswj synergistic optimization
Cov pa oxygen yog qhov tsis zoo nrog cov ntsiab lus nitrogen thiab lwm yam, kom tsis txhob muaj kev cuam tshuam ntawm nitrides ntawm cov hlau.
Txiav thiab Vuam Cov Ntawv Thov
- Oxygen Txiav
Cov pa oxygen yuav tsum tau tswj hwm ntawm 50-60}}% kom ntseeg tau tias cov hlau oxidation zoo (FE + O₂Feo) thiab zam kom tsis txhob muaj cov chaw lossis cov khoom seem.
- Vuam Kev Tswj Xyuas Zoo
Cov oxygen conctration nyob rau hauv lub chaw vuam ib puag ncig yuav tsum tau tsawg dua {{0% los tiv thaiv oxide suav nrog ua rau weld embrittlement.
