摘　　要：利用水力学模拟实验,对210 t转炉非均匀供气模式对熔池混匀时间的影响展开研究。结果表明,调整两个底吹元件对应的非均匀底吹供气模式有利于底吹流股对熔池的搅拌,并且此影响与两个底吹元件的相对位置存在一定的关系;将非均匀底吹供气模式应用于实际转炉冶炼过程中,试验发现,当采用非均匀底吹供气模式时,脱碳效率与脱磷效率均较常规工艺有所增大,碳氧浓度积有所降低,其中调整对角线两个底吹元件对应方案变化最为明显,其脱碳效率与脱磷效率分别为常规工艺的1.07倍与1.06倍,碳氧浓度积较常规工艺减小10.54%。The influence of non⁃uniform gas supply mode on the mixing time of bath in 210t converter is studied by hydraulic simulation experi⁃ment.The results show that adjusting the non⁃uniform bottom blowing gas supply mode corresponding to the two bottom blowing elements is beneficial to the stirring of the bottom blowing stream to the bath,and the influence is related to the relative position of the two bottom blowing elements;the non⁃uniform bottom blowing gas supply mode is applied to the actual process.The test shows that when the non⁃uniform bottom blowing gas supply mode is used,the decarburization efficiency and dephosphorization efficiency are increased compared with the conventional process,and the endpoint carbon⁃oxygen equilibrium is reduced.The corresponding scheme of adjusting the diagonal two bottom blowing ele⁃ments changes most obviously,and the decarburization efficiency and dephosphorization efficiency are 1.07 times and 1.06 times of the con⁃ventional process,respectively,the endpoint carbon⁃oxygen equilibrium is reduced by 10.54%compared with the conventional process.
