Through the research on the existing steelmaking process,the paper introduces the practical application of hot metal adding after the top bottom combined blowing converter tapping.This production process calculates the amount of hot metal re-mixing according to the composition and temperature of hot metal from the converter by controlling the composition,temperature and tapping amount in advance,so as to ensure that the chemical composition and temperature of molten steel meet the standard,and also meet the on-site production rhythm.The practice results show that the method of hot metal re-mixing after converter tapping can effectively utilize the advantages of high heat and element content in hot metal,realize the consumption of steelmaking components and materials,and have obvious economic benefits.
