Abstract：Pointing to the problems of nozzle clogging and poor liquidity in the casting process of converter smelting steel 20CrMnTi in Laiwu Steel, the nozzle blockage was analyzed. It was found that the main reasons are Al2O3 inclusions floatation inadequate and serious molten steel secondary oxidation. Through a series of measures such as optimizing the converter operation to improve the effect of ladle bottom blowing effect, introducing the caster parcel intelligence argon blowing system to optimize the casting process with whole-process protection, the liquidity of 20CrMnTi molten steel smelted with converter was effectively improved.
