Ntawm ib sab tes, oxygen xav tau thaum lub sij hawm cov txheej txheem cua sov ntawm Molten Steel, leej faj thiab lwm yam kev phom sij hauv Molten hlau los txhim kho cov hlau ua kom zoo. Ntawm qhov tod tes, oxygen lwg me me hauv Molten hlau yuav cuam tshuam rau cov khoom siv mechanical thiab lub zog ntawm cov hlau. Yog li ntawd, hlau yuav tsum tau deoxidised, uas yog ib qho tseem ceeb heev.
- Thaum lub sijhawm cov kev sib tw ntawm cov hlau, oxygen yuav nag lossis daus hauv daim ntawv ntawm feo, muab faib rau cov khoom sib xyaw, txo cov khoom siv roj hmab thiab lwm yam khoom siv ntawm cov hlau. Tsis tas li ntawd, cov pa oxygen yaj nyob rau hauv cov hlau molten yuav tsim cov oxides nrog lwm cov khoom hauv cov hlau, thiab cov tshuaj oxides yuav cuam tshuam cov khoom yas, kev siv ob tog thiab cov hlau.
- Hauv cov txheej txheem solidined, raws li oxygen sloubility txo qis, ntau dua li cov pa roj oxygen uas yuav muaj cov pa roj npuas ntau dua, uas yuav txo cov purity thiab cov khoom ntawm cov hlau.
- Oxygen thaum lub sijhawm ua rau exacerbates ntau qhov kub npau taws ntawm cov leej faj hauv hlau.
