Development and Production for Al-killed Low Carbon and Low Silicon Steel
MIAO Zhenlu
Abstract：Reasonable ladle refining slag system was produced by deoxidizing and slag forming process by converter tapping procedure, CAS processing procedure, RH processing procedure, which created good conditions for adsorbing the impurities in molten steel fully. Residual Al2O3 in the molten steel was spheroidized and most Al2O3 in the molten steel has been changed into liquid CaO-Al2O3 by Ca treatment procedure, which created conditions for caster casting successfully. The production of Al-killed low carbon and low silicon steel by KR-BOF-CAS-RH-CCM process route can control the content of[Si]in molten steel within the range of design requirements of steel composition.
