摘要: 针对唐钢50 t复吹转炉,采用1:6.35水模型的正交试验,研究了氧枪枪型、枪位、顶吹流量和底吹流量对熔池混匀时间、穿透深度、冲击面积和喷溅量的影响。结果表明,与4孔氧枪相比,使用改进后的4孔变角氧枪可增加对熔池的冲击面积,降低穿透深度和炉口溅出量,缩短混匀时间。对于50 t复吹转炉实际枪位≤1.3 m,有利于缩短冶炼时间,提高冶炼强度;顶吹流量控制在13 000~14000 m3/h,可缩短混匀时间和减少炉口溅出量。

Abstract: Effect of oxygen lance nozzles, lance level, top blowing rate and bottom blowing rate on bath mixing time, penetrating deptht impact area and splashing amount has been studied by orthogonal design test using 1: 6.35 water model for a 50 t top and bottom combined blown converter at Tang steel. Results show that as compared to original 4-hole oxygen lance, with using improved variable angle 4-hole oxygen lance the impact area in bath increases, the penetrating depth and splashing amount decrease while the mixing time decreases. For the 50 t top and bottom combined blown converter the real lance lever ≤1.3 m is available to decrease tap to tap time and increase intensity of bath stirring; and the mixing time and splashing amount decrease by controlling top blown rate 13 000 ~ 14 000 m3/h.
