Method capable of improving pourability of silicon deoxidized steel grade

The invention relates to the technical field of steel metallurgical steelmaking, in particular to a method capable of improving pourability of a silicon deoxidized steel grade. The method comprises the following steps: adopting silicon-calcium-barium to deoxidize a converter; starting argon gas bottom-flowing to stir after an LF refining furnace gets in, and performing molten steel oxygen quantification within 1.5 minutes to 2.5 minutes; quickly adding a slag regulating agent during early-stage slagging according to the oxygen qualifying data, adding 50kg of the slag regulating agent per furnace while oxygen content is quantified to be lower than or equal to 30 ppm, adding 80kg of the slag regulating agent per furnace while oxygen content is quantified to be 30-50 ppm, adding 120 kg of theslag regulating agent per furnace while oxygen content is quantified to be higher than 50 ppm; paying attention to a furnace slag change condition, and enabling the furnace slag to reach the effect of yellow and white slag;
