Ua ntej ntawm tag nrho cov hlau cored hlau pub tshuab yog ib hom kev tawm ntawm qhov cub refining thev naus laus zis, kev tsim cov hlau cored hlau yuav tsum tau siv ntau cov hmoov hlau uas yuav tsum tau qhwv los ntawm cov pa roj carbon tsawg, siv cov hlau feeder xav tau. siv los hla cov slag txheej ntawm ib qho kev ceev, cov hlau cored hlau yuav raug pub rau hauv cov dej steel ze rau hauv qab ntawm cov hlau ladle.
Yog li cov kua hlau rau deoxidation, desulphurisation, alloy muaj pes tsawg leeg zoo-tuning, suav nrog denaturation thiab lwm yam kev kho mob, kev siv cov tub ntxhais hlau hlau zoo tuaj yeem txhim kho qhov huv ntawm cov hlau thiab steel intrinsic nqi, thiaj li ua tiav lub hom phiaj ntawm kev txo nqi. , vim kev siv cov tub ntxhais hlau hlau yuav tsum tau xa mus kom ncav cuag qhov tob ntawm cov kua hlau, kom nws tuaj yeem kov yeej lub ntiajteb txawj nqus ntawm qee yam alloying ntsiab yog lub teeb, tsis tshua muaj melting point, thiab cov pa oxygen nyob rau hauv cov hlau ntawm affinity. ntawm tsis yooj yim rau muab ntxiv rau hauv lub cub tawg los yog Sib cuag nrog slag, theem nrab oxidation hlawv thiab lwm yam tsis zoo.
Cored hlau yog tsim rau steelmaking thiab casting. Siv hauv steelmaking tuaj yeem ua kom huv cov ntaub ntawv hauv cov hlau, txhim kho cov castability ntawm cov hlau, txhim kho kev ua haujlwm ntawm cov hlau, thiab tuaj yeem txhim kho cov txiaj ntsig ntawm cov hlau, txo cov alloy noj, txo tus nqi ntawm steelmaking, cov txiaj ntsig tseem ceeb ntawm kev lag luam.
Yog li xav ua kom cov tub ntxhais hlau hlau ua lub luag haujlwm loj dua, tom qab ntawd kev siv kom raug yog qhov yuav tsum tau ua ua ntej, tshwj xeeb tshaj yog nyob rau hauv steelmaking, casting txheej txheem.
