Ua ntej ntawm tag nrho cov, alloy cored hlau noj tshuab yog ib qho kev tawm ntawm lub cub tawg refining tshuab. Txhawm rau ua cov hlau cored hlau, ntau cov hmoov txhuas yuav tsum tau coated nrog cov hlau tsis muaj carbon steel. Thaum siv, cov hlau feeder yuav tsum hla lub slag txheej ntawm ib qho ceev kom xa cov hlau cored hlau mus rau hauv cov hlau molten ze rau hauv qab ntawm lub ladle.
Qhov no tuaj yeem siv los de-oxygenate cov hlau molten, tshem tawm sulfur, kho kom zoo ntawm cov hlau alloy, thiab hloov cov khoom ntawm cov khoom sib xyaw. Kev siv cov hlau cored hlau zoo tuaj yeem txhim kho kev huv ntawm cov hlau molten thiab cov khoom siv ntawm cov hlau, yog li txo cov nqi. Txij li thaum cov hlau cored hlau yuav tsum tau xa mus tob rau hauv cov hlau molten thaum siv, nws tuaj yeem kov yeej qhov tsis zoo ntawm qee cov ntsiab lus hlau, xws li lawv qhov tsis tshua muaj lub ntiajteb txawj nqus, qis melting point, muaj zog affinity rau oxygen hauv cov hlau, thiab lawv cov teeb meem. nyob rau hauv muab ntxiv rau lub cub tawg los yog tuaj rau hauv kev sib cuag nrog lub slag, nrog rau theem nrab oxidation thiab hlawv.
Cored hlau yog tsim rau steelmaking thiab casting. Siv nyob rau hauv steelmaking, nws muaj peev xwm purify daim ntawv ntawm steel inclusions, txhim kho lub castability ntawm molten steel, txhim kho cov kev ua tau zoo ntawm steel, thiab ho txhim kho cov yields ntawm alloys, txo alloy noj, txo steelmaking nqi, thiab ua tau zoo nyiaj txiag pab.
