Abstract In order to increase the converter capacity, effectively reduce the cost consumption, and realize the reduction of consumption and increase of efficiency, cost and increase of efficiency, increase of quality and increase of production and increase of efficiency, Beiying steel plant promotes the converter process optimization under the existing equipment and process conditions, by means of increasing the oxygen supply intensity, optimizing the combined blowing process and smelting with less slag, the converter process time and smelting cycle can be shortened by about 5 min/furnace, and some technical indexes have reached the best level in history, the oxygen supply intensity and carbon-oxygen deposition of the combined blowing are close to the advanced level in China.
