Kev siv cov cib refractory rau steelmaking yog qhov tseem ceeb thiab cuam tshuam ncaj qha rau lub neej thiab cov nqi smelting ntawm steelmaking rauv. Yog li ntawd, thaum xaiv cov cib refractory, ntxiv rau kom ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem smelting, nws tseem yuav tsum tau siv cov peev txheej tsim nyog raws li qhov xwm txheej, thiab txuas ntxiv txhim kho lub twj tso kua mis cov khoom siv calcination thiab cib ua tshuab, thiaj li yuav tau txais kev tsim nyog. refractory bricks thiab ua tiav lub hom phiaj ntawm lub neej ntev rauv taws thiab noj tsawg.
Tam sim no, cov cib refractory siv rau hauv ob sab phlu ntawm oxygen converters yog cov alkaline refractory cib uas muaj cov pa roj carbon, xws li tar dolomite cib, tar magnesium dolomite cib, tar magnesium cib, magnesia carbon cib, thiab ntau yam impregnated cib. Tsis tas li ntawd, muaj cov tshuaj tua hluav taws-resistant txheej rau phom.
Txij li thaum tau txais cov pa oxygen converter steelmaking, ntau lub teb chaws feem ntau tau siv magnesium thiab dolomite refractory cib ua rau lub qhov cub hauv ob sab phlu, los yog muab sib xyaw ua cov cib refractory siv. Tag nrho cov qauv yog mus rau kev txhim kho cov purity ntawm raw cov ntaub ntawv, tsim nyog nce cov ntsiab lus ntawm magnesium oxide, ua rau kom qhov ceev ntawm refractory bricks, thiab ua kom cov residual carbon ntsiab lus. Qhov zoo ntawm qhov cub hauv ob sab phlu refractory bricks yog maj mam txhim kho, thiab ntau yam kuj tseem nce ntxiv.
