通过实验,研究了顶吹氧量、枪位和喷头型式对纯顶吹熔池搅拌强度的影响,底吹气量、风嘴数目、直径和布置及熔池深度对纯底吹熔池搅拌强度的影响,以及不同顶、底吹关系下(包括顶吹超软吹和非超软吹,底吹小气量和大气量等)的复吹熔池搅拌强度。从而提出了表述顶底复吹转炉熔池搅拌混匀时间的半经验式:T_(0·c)=K·T_(0·T)~a·T_(0·b)~b,及纯顶吹和纯底吹的熔池搅拌混匀时间半经验式。
Through experiment, the influence of top blowing oxygen, gun position and nozzle type on stirring intensity of pure-top-blown molten pool was studied. The effects of bottom blown air volume, number of tuyeres, diameter and arrangement and depth of melt pool on the stirring intensity , And the mixing intensity of the compound blowing bath under different top and bottom blowing conditions (including top-blowing super-soft blowing and non-super soft blowing, bottom blowing air volume and air volume, etc.). Therefore, the semi-experiential formula is given to describe the time of mixing and mixing in the top-bottom double-blown converter bath: T 0 c = K T 0 t - a T 0 - b b, Blowing and pure bottom blowing pool mixing time semi-empirical style.
