Practice of Alloying Operation after Deoxidizing for Low Carbon Aluminum-Containing Steel by 90t Converter
Aiming at the problem that the alloy yield was low in smelting the low carbon alu-minum-containing steel by 90t converter,the main causes leading to the low alloy yield were an-alyzed. After optimizing the content of oxygen in molten steel at the end point and the ratio of al-loying after deoxidizing,adjusting the compositions in slag and applying the slag stopper reason-ably,the consumption of deoxidized aluminum was reduced and the alloy yield was increased to 87.4％ and therefore the total cost for alloy was reduced by more than 7 yuan per ton.
