As one of the most important process equipment in oxygen converters,the smelting effect and blowing time were directly affected by oxygen lances,their performance will thereby have impacted on the final steel performance and output.As we all know,oxygen lances function by interactive blowing through the interaction between oxygen jet stream and molten pools,which depends on the oxygen impingement speed,area and depth when it reaches the surface of molten pools;thus,it is of great significance to optimize the process parameters and reasonable structural design of oxygen nozzles.This article calculated the working parameters of the oxygen lance nozzles in Bensteel sheet steelmaking plant,combined with the actual working conditions on site,and obtained the most suitable operating mode for Bensteel.
