The invention discloses a low-cost converter steelmaking deoxidization process. The process is characterized in that in the converter steel tapping process, carbon powder and a composite deoxidization agent are added for segmented deoxidization, the content of total oxygen in molten steel is reduced by controlling the deoxidization occasion and optimizing the steel tapping deoxidization operation process, the low-price carbon powder and the composite deoxidization agent are used for replacing a traditional aluminum and iron deoxidization agent, deoxidization cost can be greatly reduced, and meanwhile, non-metallic inclusion is reduced. By means of the deoxidization process, the ratio of inclusion, with the level smaller than or equal to 1.5, in steel is increased to 98.21%, the continuous casting fluctuation flow rate is reduced to 0.32%, the deoxidization cost of each ton of steel is reduced by 1.58 RMB yuan, and profit margin is increased for enterprises while steel quality is improved.
